The safety catcher and the ratio-clamp are both clamping units. One main difference is the fact that the safety catcher only holds vertical loads, while the Ratio-Clamp can hold vertical and horizontal load. This is because the safety catcher utilizes a self-energizing principle. Unlike the Ratio-Clamp, the safety catcher does experience a small amount of downward movement to generate the holding force, rather than clamping in the exact position. If you’re not sure which device is better for your system, contact an engineer for more information.
No. The safety catcher prevents falling on vertical, gravity-loaded axles when the power fails or the machine malfunctions. It is used as a safety device so that the load does not harm people, the equipment, or the environment. Because it uses a self-energizing principle to generate the holding force, it does not require power to work.
The safety catcher is certified through the DGUV Test, confirming that the clamping unit is tested as a safety-related component according to European standards such as EN ISO 16092-1/-3 for presses. It simplifies the risk assessment of the overall machine, as the protective function is officially proven. The holding load of the safety catcher for machines has a safety factor of at least 2 but does not exceed a safety factor of 2.8.
The Hänchen Safety Catcher is used for clamping round rods in vertical, gravity-loaded axles. It ensures reliable safety mechanisms for stepless securing of loads at a standstill, as a safety component in case of emergency, or for effective fall protection.
The safety catcher mechanically locks based on a self-energizing principle and supports both compressive and tensile loads. Unlocking is achieved via hydraulic or pneumatic pressure.

Hydraulic Test Cylinders are used in a wide variety of applications including automotive testing such as lifecycle tests, aerospace system tests such as load and environmental condition simulation, and fluid power operating condition simulation.
Automotive
Servo hydraulic lifecycle tests are the current industry standard for automobile components that are used far beyond safety-related structural elements. Users can depend on hydraulic test actuators for high positioning accuracy and reliability in applications for test systems and real time control. A test cylinder with a dynamic lift of up to 35 mm (1.3 in.), speed of 1.3 m/s (51.2 in/s), and acceleration of up to 50 m/s (1968.5 in/s) could be used for a test load requiring up to 28 kN (6,294 lbf) and a frequency up to 20 Hz.
Aerospace
System tests that simulate loads and environmental conditions in different flight phases are particularly demanding. To test the landing flaps and slats, servo hydraulic cylinders could be used here to replicate the airflow that involves rapidly changing forces with irregular parameters. For example, a servo cylinder with a bore between 40 to 160 mm (1.5 to 6.2 in.) could be used for a test stand with a holding force between 140 – 300 kN (31.4 to 67.4 lbf) and a stroke requirement of 300 to 1,670 mm (11.8 to 65.7 in.).
Fluid Power
To determine the characteristic values of a seal, seal test benches are suitable for simulating a wide range of operating conditions. Double rod cylinders could be used here for fatigue tests focused on examining the frictional force of the seals, tightness on rods and shafts.
Hänchen offers 5 cylinder cover sealing systems and 4 guide options to provide very low friction and minimize stick-slip for all those that need it.
On the market today, there are two standard sealing options for the cylinder cover: a basic design with a lip seal and wiper ring or hydrostatic functional oil seals. To address in-between friction and stick-slip needs, Hänchen offers these, plus additional sealing options.
Sealing pressure and temperature
We offer sealing options handling pressures up to 29,000 psi (2,000 bar) and temperatures from -40 °F to 392 °F (-40 °C to 200 °C).

The maximum frequency we can achieve is up to 1,000 Hz. While it is theoretically possible to design our cylinders for any frequency, the main limitation is the valve control technology. Our cylinders are capable of higher frequencies than most valves on the market can support. This means the maximum frequency you can achieve is limited only by the valve’s capability, not the cylinder itself.
The recommended operating temperature range depends on the lowest and highest temperature limit of selected seals and materials.
Engineers must consider the material’s permissible tensile strength and seal temperature limits at low temperatures. In this case, special attention should be given to the notched impact strength, which decreases as the temperature drops and affects the material’s resistance to sudden loads.
Materials with specific properties must be used to ensure reliable toughness values even at low temperatures, for example at –22 °F (–30 °C) or –40 °F (–40 °C).
In the area of the sealing elements, care must be taken to select the proper material. For instance, different NBR mixtures have different temperature properties and therefore the temperature limit is not necessarily defined by the simple material name, for example, NBR.
Seals for temperatures down to 5° F (-15 °C) are permitted as standard. Special seals can be used for low temperatures.
14-18 weeks lead time, including manufacturing and shipping.
Specialty cylinders are manufactured in 7-16 weeks in Germany and then shipped by air-freight (2-week shipping).
It can be difficult to put a number on the lifetime of a Hänchen cylinder. This is because it’s very application dependent. A cylinder in a concrete crushing application that is exposed to constant concrete dust in the air isn’t going to last as long as a cylinder in a clean environment. However, the rigidity, honing, in combination with the right sealing and material can mean that Hänchen cylinders last a long time. It is not uncommon for cylinders to last 20, even 30 years with only seal kit changes.

Series 320
The Series 320 cylinders are used in highly dynamic testing and motion control applications where high cycling accuracy is required, oftentimes with low amplitudes. It supports variable displacement profiles with stable performance under load.
Sealing Systems The Series 320 uses Servofloat®, Servobear®, or Servoseal® sealing systems. The piston is fitted with either a gap seal or Servoseal®.
Cylinder Design The cylinder body has a rigid construction that limits vibration. Optional conical protection tubes reduce lateral movement in fast or high-force conditions. All models use a double-rod configuration with bore sizes offered in 1 mm increments.
Mounting and Sensors The Series 320 includes a mounting plate that supports control valves and allows accumulators to be attached for pressure regulation to smooth out the dynamic movement. Inductive and magneto strictive transducers can be integrated for position sensing.
Typical Applications The cylinder is typically used in test systems demanding precise motion, high cycle rates, and consistent displacement control.
Series 120 and 300
The Series 120 and 300 cylinders are designed as compact alternatives to classic test actuators for simple testing tasks. When equipped with a mounting plate and position transducer, they deliver precise performance for static and dynamic test applications.
Sealing Systems Servocop®, Servoseal®, or Servofloat® sealing systems are available on the cover, combined with Servoslide® guide systems or PTFE wear rings. On the piston, either a rectangular compact seal or Servoseal® is used for test applications requiring consistent sealing performance.
Cylinder Design These cylinders feature a lightweight, rigid design ideal for long strokes or for applications where the cylinder must move with the test structure, such as pivoting movements.
Single-rod: supports static or low-frequencies up to 7 Hz.
Double-rod: supports dynamic frequencies up to 25 Hz.
Mounting and Sensors Compact mounting plates allow the integration of lightweight control valves and position transducers, forming a complete and efficient test actuator assembly.
Typical Applications Series 120 and 300 cylinders are typically used in simple test setups requiring precise linear motion with moderate dynamic loads and minimal actuator mass.
Choosing a single or double-rod cylinder depends on the force ratios, dynamics, and lateral vibrations.
Up to 7 Hz: use single-rod (Series 120 or 300)
Up to 25 Hz: use double-rod (Series 120 or 300)
Over 25 Hz: use double-rod (Series 320)
Single-rod, Series 120, 300 (up to 7 Hz)
Single-rod cylinders are suitable for moderate dynamics with frequencies up to 7 Hz. Higher frequencies can also be achieved, depending on the dynamics of the control valve used, the travel speed, and the cylinder size. Asymmetrical control valves may have to be used for this purpose.
Double-rod, Series 120, 300 (up to 25 Hz)
Above a certain dynamic, it is advisable to work with equally large effective areas on the cylinder. For example, it is recommended to use double-rod cylinders for up to 25 Hz, as most control valves have symmetrical surfaces.
Besides the hydraulic limits, even the mechanical properties play an important role. At exceptionally high frequencies, very heavy and stiff cylinders are preferred to prevent the cylinder from swinging up due to transverse acceleration. For example, this can be achieved by using heavy, conical protection tubes.
Double-rod, Series 320 (above 25 Hz)
For applications exceeding 25 Hz, the Series 320 is recommended.
For short strokes or low-amplitude movements (for example, around ±1 mm) over an extended period, contact seals can cause friction and significant wear because the surfaces move too little to maintain lubrication.
In such cases, non-contact sealing or guiding systems are recommended such as Hänchen’s Servobear® (commonly referred to as hydrostatic), Servoseal®, Servofloat®, or Servobear®). This design avoids surface scoring and provide smoother motion.

HYDRAULIC PRESSURE INTENSIFIERS – SINGLE-STROKE CYLINDER TYPE
Hydraulic Pressure Intensifiers – Single-Stroke Cylinder Type
The Hänchen intensifier is a custom, heavy-duty, pressure intensifier designed for non-standard applications. This model allows the input fluid to be the same as, or different than, the output fluid as a result of its non-reciprocating, axial type construction. Specifically, the primary cylinder can be run with mineral oil and the secondary chamber can be run with a different fluid such as water or water containing media. This type is commonly found in the hydroforming industry. Additionally, higher flow rates can be achieved in this type of pressure intensifier. These pressure intensifiers can be designed with output pressures of up to 5,000 bar/72,500 psi.
Hänchen is a supplier and pressure intensifier manufacturer for various applications including construction, mechanical, marine, and industrial.
The MP-S Series offers the most compact in-line pressure intensification solution to deliver increased pressure precisely where it’s needed when space is at a premium.
The Ratio-Clamp is a rod-locking device that is used both for precise locking and for securing against unintentional movements. It uses the principle of frictional contact to do so. When the releasing pressure drops, the force stored in the springs is discharged, causing the rod to clamp through friction. This means no power is needed to hold the position. To unclamp, hydraulically release pressure to release the clamping force.
The Ratio-Clamp has a max holding load of 101,164 lbf (450 kN) and covers rod diameters from 0.709 inches (18 mm) to 5.512 inches (140 mm).
The Ratio-Clamp is approved by the German Technical Inspection Agency (TÜV). For more information on Ratio-Clamp as a certified safety device, reach out to our engineers.
The Ratio-Clamp holds the exact position when releasing pressure drops, while the safety catcher, due to its self-energizing principle, experiences some movement before fully stopping. This makes the Ratio-Clamp the better choice in applications where exact positioning is important, such as testing and simulation. Additionally, the Ratio-Clamp can perform on horizontal axles as well as vertical in both directions, while the safety catcher can only be used on gravity-loaded vertical axes in one direction (down).
Hydraulic Cylinders — Rod-Locking Device
The Hänchen Ratio-Clamp® keeps the position for you. This device is a positive rod clamping safety device. The Ratio-Clamp is unlocked by hydraulic pressure. In the event of an electrical/hydraulic power loss, the potential energy of the internal Bellville washers load a conical piston, driving it over the friction fingers resulting in securing the load. “A true self contained safety clamp.”
Wherever power failures or malfunctions pose a risk to the safety of people or machinery, the rod locking device is there to save the day. It is also useful to accurately hold the cylinder rod in an exact position without the need to keep hydraulic pressure on the cylinder, thereby saving energy while maintaining accuracy. It clamps down and fixes the piston rod right where it is with no additional power needed.
Advantages of hydraulic rod locks
No axial rod movement during clamping and releasing
Protective clamping effect in case of a power failure
Load capacity that is independent of direction
Clamps completely surrounding rods
IoT 4.0 Compatible: Integrated sensors to know if the clamp is locked or unlocked
Boasting a retention force of up to 101,000 lbf., the clamp hydraulically holds the piston rod in whatever position it is in at that particular moment without having to generate extra power (no extra energy) for an unlimited period of time. The clamping device Ratio-Clamp is approved by the German Technical Inspection Agency (TÜV).
Special development of Custom solutions (larger rod diameters, intermediate size, greater clamping forces) pose no problem for the Hänchen specialists. Hänchen is particularly proud of its RC-H model. Following a request from the Health and Safety Centre of the Employers’ Liability Association (BGZ iron and metal section III, Düsseldorf), Hänchen developed the new safety clamping hydraulic Ratio-Clamp under extreme conditions for use with hydraulic presses and injection molding machines.

Ratio-Clamp Applications
Testing technology in aviation: The setups for aviation tests have been refined to the last detail. Cylinders are used in different fields of testing, simulating ambient conditions and loads during different flight phases. The Ratio-Clamp® is used to protect the intricately constructed and expensive systems.
Production in molding and injection presses: Clamping units ensure safety during the pressing process in molding and injection presses for the production of synthetic and rubber molder parts in accordance with EN 289.
Maintenance in railway technology: During maintenance, trains must be fixed in a raised state. The Ratio-Clamp® is ideally suited for this purpose, as it holds the train securely in position until the work had been completed.
Production in grinding machines: During the production process of ICE rail sleepers, extremely large and heavy concrete workpieces must be positioned for grinding safely and with an accuracy of 0.01 mm. Hänchen’s hydraulic cylinders and Ratio- Clamp® clamping units are designed exactly for these requirements.
Production in profilling machines: Hänchen clamping units ensure precise machining and consistent quality in the production of metal profiles. During the production process, they facilitate the machining of the profiles by locking the forming tools in place. Ecological and efficient, purely with spring power.

* When pivot mounted, the pressure is limited to 1740 psi (120 bar).
F1 Compressive force while the cylinder is extended
F2 Compressive force while the cylinder is retracted. With double-rod cylinders, retraction and extension corresponds to the value of F2.
Choosing a Testing Cylinder
Dynamic Movement
First, determine if the cylinder will be used in highly dynamic applications, such as torque/torsion testing of axial loads and other drive line components. If so, seal protection is important to have, along with a servo valve that can be mounted to the actuator to offer more control to the device. It is important to know the application including the speed, pressure, loads, and any forces acting on the cylinder.
Frequency
What frequency will your cylinder require? Industrial applications and dynamic testing typically have higher frequency ranges, with some frequencies greater than 100 Hz.
Seals
It’s important to pay attention to the conditions your cylinder will be in. Conducting tests in conditions like salt spray fog, in climate chambers, or in a lab require individualized protection. Seal factors to pay attention to include temperature ranges, types of movement (simple, sensitive, controlled), outdoor stress, stick resistance, and type of medium, etc.
Load Holding
If loads need to be held in position for extended times, a rod lock can be included which allows a load to be held in a precise position and without power/pressure being applied.
For over 100 years, Hänchen has supported the test and simulation industry with actuators built for precision and durability. Our servo cylinders cover one of the widest ranges on the market.

Generations of European Craftsmanship and Manufacturing
Anyone can sell you a part. As a distributor, we offer more than just cylinders.
Our roots run deep in hydraulic manufacturing. Our President, Ben Hunger, comes from the family business behind some of the world’s largest hydraulic cylinders. The founder of IC-Fluid Power, Armin Hunger, established the company to bring German precision and quality to the U.S. market. He built strong, lasting partnerships with European manufacturers, many of whom we still work with today. Through these connections, we provide access to European partners with over 100 years of expertise in premium cylinder manufacturing.
The right material determines the cylinder’s strength and lifespan. Choose from standard steels for general use, stainless steels for corrosion resistance, or lightweight alternatives like aluminum and carbon hybrids for mobile or specialized applications.
This is just a sampling of the common materials we use, but any specialty material is possible.

Choose a single-rod style for standard linear motion, a double-rod style for equal force in both directions, or a telescopic version when space is limited but stroke length is long. Tie-rod and welded cylinders differ in how they’re built. (Tie rods use long threaded rods to essentially sandwich the cylinders body together, while on welded cylinders the body components are welded together.)

Single or Double-Acting Cylinders
Hydraulic cylinders are available as single or double-acting:
Single-acting cylinders use hydraulic fluid for movement in one direction that returns by gravity via dead weight or a spring.
Useful when automation return is needed for safety if pressure is lost
Standard applications
Double-acting cylinders use hydraulic fluid in both directions.
Useful when you need both forces to be equal
High speeds and high frequency applications
Useful for when a load needs to be attached to both cylinder ends (rare)
We offer a wide range of media for applications, selected based on the required viscosity, thermal stability, oxidation resistance, lubricity, and water tolerance.

Popular Choices for Patented Sealing Solutions
1. Servofloat® seal for low friction and high side loads
For testing and simulation, we offer over 12 different combinations for achieving low stiction and stick slip. One popular option for dynamic tests that require near frictionless movement is the patented Servofloat® seal. This works using a floating-gap principle to eliminate stick-slip. It enables extremely smooth oscillations at frequencies up to several hundred hertz, a key benefit for servo-drive applications.
2. GD1000K® for reliable sealing and guidance for heavy-duty conditions
The GD1000K® is a piston seal made for heavy-duty industrial and construction applications. It guides the piston and keeps it sealed using a bronze-filled PTFE slide ring and NBR energizing element. It maintains proper sealing even at zero pressure and prevents metal-to-metal contact under heavy side loads. The combined bearing and sealing give double-acting cylinders improved structural rigidity.
Standard Sealing Options
Not every application needs a specialty seal. Standard sealing options offer high performance for most cylinders. A common setup uses a lip seal together with a wiper ring to keep contaminants out and maintain sealing integrity. Static seals stop leakage at fixed interfaces, while dynamic seals control fluid between moving parts such as the piston and rod.
Dynamic Seals
Element / Seal Location
Common Types / Examples
Piston seals
U-cup seals, T-seals, rectangular seals with elastomer, PTFE-backed seals, throttle gap seals, V-packings
Rod coatings protect piston rods from things like wear, corrosion, micro-scoring, and more to extend the service life of the cylinder. We offer standard surface treatments, such as classic nitriding and hard chrome plating. For large piston rods exposed to abrasive conditions, we also offer specialized coatings well suited for hydromechanical, chemical, offshore, and subsea environments.

Piston Rod End Mounting
Piston rod ends differ in their fixation and mounting types.
Fixation Types
Each fixation type refers to the way the piston rod is mechanically connected or threaded for attachment to external components. The chosen fixation determines how forces are transmitted and how the rod end can be mounted.

Mounting Plates for Valves or Threaded Fittings
We can build a mounting plate for direct installation of servo valves or directional control valves onto the cylinder head, minimizing pressure losses, and improving hydraulic response. The correct mounting surface is selected based on flow capacity, valve type, and application-specific requirements. Hydraulic oil connections are the same as the ports previously described.
The chart below features commonly used port types, but any can be made.

Sensors can be added for automation to measure and monitor critical changes in the system. These sensor integrations connect smoothly with automation platforms using Industry 4.0 standards. This allows for real-time data monitoring, predictive maintenance, and closed-loop control, which all contribute to better system reliability and performance.
Popular sensor options for traditional and Industry 4.0 compatible systems can be found in the list below:
Proximity switches measure precise end-of-stroke position to detect stroke limits and confirm end position
Position/stroke sensors measure piston rod position to provide feedback and enable closed-loop control
Temperature sensors measure fluid, cylinder, or surface temperatures for monitoring and to prevent overheating
Pressure sensors measure hydraulic pressure in chamber or line to prevent overloads
Force transducers measure axial force to monitor the applied load and verify test parameters
As a primary distributor for many international cylinder manufacturers, IC-Fluid Power is capable of several different painting options from single acrylic coatings for standard cylinders to advanced multi-layer epoxies and urethanes made for offshore and military coatings.
Standard Options
Cylinders can be left unpainted with or without temporary transportation and storage corrosion protection (VCI, wax, silane, phosphate, grease)
Primer only (acrylic, epoxy, or other as specified)
Base coatings use 1k synthetic epoxy or acrylic paints for general environmental resistance
Specialty Options
Specialized coatings include robust 2K epoxy systems.* These offer high adhesion and chemical resistance suited for offshore, mining, and industrial conditions. This durable coating is used to withstand intensive mechanical and chemical stress while offering exceptional coverage and scratch resistance.
Military-grade coatings meet specific defense or government requirements and are provided upon request.
Offshore coatings use multi-layer epoxy or polyurethane systems to withstand saltwater exposure and harsh marine exposure.
*For customized cylinders made from Germany, our Hänchen cylinders are finished with a 2K polyurethane structural paint (silicone-free) in RAL 9006, white aluminum semi-gloss.
Cushioning is added to gradually slow the piston as it nears the end of its stroke, protecting the cylinder and connected equipment from impact damage and excessive shock loads.
Our hydraulic cylinders can be equipped with standard or advanced cushioning systems with customized orifices.
IC-Fluid Power’s Advanced End-Cushioning Options
Cushioning can be either added in the cap/head and the bottom. The following characteristics that can be customized:
Cushion spear length
Needle valve size and adjustment per flow rate
Cavity shape and size
Cushion design (tapered or orifice)
Cushioning profile (single stage or multi-stage with multiple adjustable needle valves, orifices, or other custom-led designs to meet application requirements)
Cushion material
Reverse stroke
Check valve (bypass valve)
We offer rod-locks (Ratio Clamp®) as an optional feature for standard and custom hydraulic cylinders providing added security and functionality.
The Ratio Clamp® is a patented hydraulic clamping device that instantly locks piston rods or round rods, holding loads up to 2,000 kN. This device incorporates a spring force that clamps the rod securely in place without continuous energy, releasing only when hydraulic pressure is applied. Since these rod locks are mechanically locking and hydraulically unlocking, they also can be used as a safety device. This is an easy way to hold a cylinder in position indefinitely while not requiring any input from your HPU (saves money too!).
