IC30 Hydraulic Rotary Actuator FAQs
Rotary Actuators – IC30 Series
The IC30 is the highest-torque model in the IC Series of helical-spline hydraulic rotary actuators, with drive torque from 16,810 to 212,410 in-lb (1,900 to 24,000 Nm) at 3,045 psi (210 bar) across eight sizes. Standard rotation is 180° or 360°, and the IC30 is offered with foot or flange mounting, and cantilever or straddle shaft support. Built for heavy-duty applications like mining and material handling, it’s a direct drop-in replacement for the Helac L30 series and ships in 20–26 weeks standard or 10–14 weeks via expedited airfreight.
Given its high bearings and precision accuracy, it is a solution for many applications that involve positioning, rotating devices, steering, and more. The IC30 series is especially built for durability and maintains high performance in the toughest and most demanding applications. Additionally, the IC Series was designed with high shock absorption to preserve the product’s life.

Cantilever Mounting
The load is securely bolted to the shaft flange. Cantilever mounting is ideal for loads needing support at only one end of the shaft, and is not advised for aerial work platforms or other critical safety-related applications.
Straddle Mounting
Straddle mounting is ideal for loads needing support at both ends of the shaft. Similar to cantilever mounting, the top of the load is bolted to the shaft flange. Then, the bottom is bolted to the end cap flange.
Counterbalance Valve
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 the 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.
Helical Spline Hydraulic Rotary Actuators
Our rotary actuators are the helical spline design. This means, a piston and a helix, or sliding spline, work together to convert the linear motion of the piston into rotational motion. Composed of two moving parts and some form of housing, the sliding helical splined gear concept within the actuator is used in many applications where a rotary movement is required. Helical Spline Actuators function when the piston is axially displaced using hydraulic pressure causing simultaneous rotation of the piston. Standard amounts of rotation are 90°, 180°, and 360°. The primary benefit to this type product compared to alternative designs such as linkages using hydraulic cylinders (linear actuators) is its compact design.
