Which series is right for my application?

Servo cylinders of the Series 120 and 300 are light-duty test actuators for simple testing tasks. For more challenging tasks, the Series 320 is a hydrostatic design offering excellent precision and high performance, allowing for high lateral forces and speeds.

General Specifications:

Bore, mm (in): 25-200 (0.98-7.87)
Force, kN (lbf): up to 1,568 (up to 352.5)
Stroke, mm (in): 1-1,500 (0.04-59.06)
Frequency (Hz): up to 100+, limited by servo valve

The 320 Series: Constructed for highly dynamic tests

Perfect for industrial applications, structure tests, and load simulations: the Series 320 test cylinder is the best choice for challenging tasks. It performs well, for example, in checking the functional safety of systems, component parts, or products; for structural testing of airplanes, refrigeration compressors, automobile exhaust system; or for simulating loads and movement, such as operational profiles and flight profiles.

The Series 320 is built from a solid block of steel. This means that any part of the cylinder can be customized to your requirements unlike standard models with limited sizing options. Rigid construction of the cylinder means means no leakage, a long service life, and good data.

4 Stand Out Features of the 320 Series:

Bores adjustable to the millimeter: The working areas can be designed individually for the respective requirements, saving acquisition and operating costs for the required periphery, and increasing energy efficiency.
Protection against unforeseen movement: Emergency cushion adds protection for the cylinder and test specimen. This is included in the stroke as standard. The effective stroke is between the two emergency cushioning.
Operation without a leak oil pump: Thanks to elaborate sealing and guiding system, cylinders don’t need leak oil pumps. The cylinders are equipped with high-quality bronze coatings for optimum emergency running properties.
Modular system efficient change of applications: Mounting parts and accessories fit cylinders with different forces and do not have to be purchased several times for one test field.

* 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.
