IC40 Series

The IC40 series has a max drive torque of 24,780 – 59,290 in-lbs at 3,045 psi (2,800 – 6,700 Nm at 210 bar). Given its high bearings and precision accuracy, it is a solution for many applications that involve positioning, rotating devices, steering, and more. The IC40 series also achieves high performance for applications needing to consistently maintain high torque outputs. Additionally, the IC Series was designed with high shock absorption to preserve the product’s life. It is also suitable for rotating applications where a standard rotation of 200° or 220° is needed.

Rotary Actuators – Counterbalance Valve Block

Actuators can be configured with a counterbalance, or load holding valve, to provide load stability and prevent the actuator from reaching excessive torque outputs. Producing back pressure in a hydraulic line gives control over a suspended load to stop unintended motion of the actuator. Valve blocks are available in steel and aluminum, and may be purchased separately if required at a later time. Spare parts are also available.

21260A Counterbalance Valve Block

Valve blocks are configured from aluminum and secured to a flat mounting pad on the actuator housing with three bolts. See each individual series page for specific valve locations. The pilot ratio is 3:1. The valves are set to relieve at 3,300 psi (228 bar).

21270 Counterbalance Valve Block

Valve blocks are configured from steel and secured to a flat mounting pad on the actuator housing with three bolts. See each individual series page for specific valve locations. The pilot ratio is 3:1. The valves are set to relieve at 3,300 psi (228 bar).

21280 Counterbalance Valve Block

Valve blocks are configured from steel and secured to a flat mounting pad on the actuator housing. Valve locations and plumbing routing differ among sizes. See each individual series page for specific valve locations. The pilot ratio is 3:1. The valves are set to relieve at 3,625 psi (228 bar).

IC Series Product Page

Hydraulic rotary actuators are vital components in various industrial applications, often requiring precise control over heavy loads. To enhance the functionality and safety of these actuators, they can be accessorized with a counterbalance, or load-holding, valve. This option ensures the stability of the load by preventing unintended movement, especially in case of a hydraulic hose failure. By creating back pressure within the hydraulic line, these valves play a crucial role in controlling the load, thus averting any accidental movements of the actuator.

Often, the counterbalance valve is used as a safety device when the safety of humans is involved by protecting the actuator and thereby the person in case of a downstream hydraulic failure or by an upstream external force. Take, for example, a man lift where a person is in a basket. If there is hydraulic failure somewhere before the basket, the basket will stay in its place. If there is a force excerpted on the same basket if the operator hits an object while moving, the basket will rotate to protect its occupant.

Furthermore, due to the small oil volume (displacement) of the rotary actuator, temperature swings between night and day can cause substantial movement to whatever is mounted to the actuator if the actuator is not actuated. So, the counterbalance valve protects the actuator from overpressure applied to the actuator, or failure of a downstream component.

On some models, counterbalance valves can also be added to the system post purchase. This option provides a practical solution for those who may need to upgrade their existing system’s capabilities. Whether incorporated during the design stage or added later, these components can enhance the control, stability, and safety of hydraulic actuators across a wide range of industrial applications.

Hydraulic Rotary Actuators – E3

The Eckart E3 is a hydraulic rotary actuator that has been especially designed for mobile applications; however, it is not limited to such applications. This rotary actuator functions according to the “helical gear” principle and, due to its compact design, only requires a minimum amount of space.

The Eckart E3 is identical in form to the products of its competitors, but has unique selling points which can offer considerable advantages: firstly, there is virtually no backlash; secondly, there is no play in the 4-point roller bearing; and thirdly, no compact seals which can be subjected to stress on both sides are used. Consequently, there is no more wobbling, such as on the work platform, when a lateral movement is made.

Hydraulic Rotary Actuators – SM4

The Eckart SM4 rotary actuator is a heavy-duty and highly-customizable rotary actuator designed for the toughest and most-demanding applications.

Because of its torque, angle of rotation, pressure range, positioning accuracy, stability of position, type of attachment, and its dimensions, the Eckart SM4 rotary actuator can be used in a wide range of applications. Not only is the SM4 a compact and robust unit, but it is also wear-resistant and efficient. The SM4 can be configured with an industry-leading fine and controllable end cushioning curve. Additionally, the SM4 unit can be driven via “black and white” or with proportional, control, and servo valves. For the purpose of subsequent driving, the piston end-positions at the linear cylinder and at the rotary actuator can be scanned via electronic end-position acknowledgement mechanisms. Ultimately, with the SM4, you have a high-performing product that is both robust and compact, allowing for optimal adaptation depending on your specific requirements.

Helical Spline Hydraulic Rotary Actuators:

Like all Eckart hydraulic rotary actuators, the SM4 is designed with helical spline technology. The actuator operates with a piston and a helical or sliding spline mechanism, which work in tandem to transform the piston’s linear motion into rotational movement.

High torque in a compact profile

  • Helical spline actuators deliver impressive torque within a compact construction, making them ideal for applications where space is limited.

Less risk of contamination and physical damage

  • Protective housing keeps all moving parts safe from debris and moisture, ensuring consistent operation in demanding environments, especially for mining applications.

Low maintenance and wear-resistant moving parts

  • All internal components are fully immersed in oil ensuring preventative wear.
  • Extended-period nitriding ensures a long service life of the rotary actuator.
  • Helical gears feature excellent sliding characteristics.

Reduced pinch points

  • Helical spline rotary actuators offer safer alternatives to linkages for the operator, since there are no exposed parts.

Standard Rotations:

Standard rotations are 90°, 180°, 270°,and 360°. Other rotations can be supplied on request by using the model with the next standard rotation up and limiting the stroke of the piston in accordance. Also available are special models with rotations in excess of 360°. Additional rotation is created by making the spline gears longer while maintaining the same diameter. The primary benefit to this type of product compared to alternative designs such as linkages using hydraulic cylinders (linear actuators) is its compact design.

Eckart is a supplier and rotary actuator manufacturer for various applications including construction, mechanical, marine, and industrial.
