Hydraulic Rotary Actuators
IC-Fluid Power supplies hydraulic rotary actuators with torque up to 2,200,000 in-lb (250,000 Nm) and pressures up to 3,625 psi (250 bar), with standard rotations from 90° to 360°. Choose custom Eckart models for specialized applications, or the IC Series for fast drop-in replacements for Helac L10, L20, and L30 actuators.
What Makes Us Different?
Helical Spline Technology
Helical gear rotary actuators are designed with space in mind and are suitable for many applications needing a compact solution.
Fast, Ready Drop-Ins
The IC Series can be used as a drop-in replacement to Helac’s rotary actuators and offers quick lead times of 20-26 weeks (or 10-14 weeks with expedited shipping.)
Customized Solutions
70% of Eckart’s rotary actuators are custom-designed to meet customer needs. Tell us your application and we will present you with an optimal solution.
Model Selector Guide
Use the chart below to match your specifications to the recommended model. Keep in mind that some requirements may overlap. Since every installation has unique torque, mounting, speed, and environmental requirements, use this as a starting point and consult our technical team to verify the best actuator for your needs.

Why? |
|
PRESSURE Operating pressure up to 3,625 psi (250 bar) |
Highest pressure rating in the lineup; required for high-force hydraulic systems. |
||
|
PRESSURE Operating pressure up to 1,450 psi (100 bar) |
Same Eckart build quality as the SM4 at a lower-pressure rating; the right choice when system pressure does not exceed 100 bar. |
||
|
MOUNTING A flange shaft mounting (cantilever/direct-to-load) |
The only Eckart model with a flange-shaft output; suited for mobile equipment and slow-moving applications where the load mounts directly to the shaft. |
||
|
TORQUE Maximum torque (above 31,800 lbs-in / 3,600 Nm) |
Reaches up to 2,200,000 lbs-in (250,000 Nm) across 13 sizes; the highest-torque option offered. |
||
|
CUSTOMIZATION Custom rotation, materials, sensors, or certifications. |
Over 70% of Eckart units ship as custom builds; IC Series does not offer speciality customization. |
||
|
HEAVY LOADS OR HIGH SPEEDS Fine end-cushioning for dynamic applications |
Tunable cushioning curve with up to 10 individual orifices. Not available on E3 or IC Series. |
||
|
REPLACEMENT A drop-in replacement for Helac rotary actuators |
Replacements for popular Helac series: L10, L20, L30, T20, T30; lead time as fast as 10–14 weeks expedited. |
With decades of experience, Eckart can design and build a quality rotary actuator to your specifications.
The SM4 rotary actuator with an operating pressure of up to 250 bar offers rotary movement with a compact footprint.
The E3 with a maximum operating pressure of 210 bar, is designed for, but not limited to, mobile applications where a flange shaft is desirable.
The E1 rotary actuator with an operating pressure of up to 100 bar offers rotary movement with a compact footprint.
The HyRAV® valve actuator is tailored perfectly to your needs. HyRAV by Eckart, comprises a full series of double-acting or spring return actuators.
The HSE4 rotary-linear actuator combines an independently controllable dual acting cylinder with a rotary actuator.
The PSM2 pneumatic rotary actuator is most suited to applications in small installation spaces with low weight specs.
The Eckart PHSE pneumatic rotary-linear actuator is a combination of a rotary actuator and a dual-action linear cylinder.
Optional load holding valves for intermediate position holding and over center conditions.
