HMR series · foot-mount · 210 bar
HMR2 helical rotary actuators
7 sizes from 508 to 5,870 Nm at 210 bar, with 180° rotations. The HMR2 range is built for steering and positioning duties on mobile equipment, where the housing bolts down onto a flat bracket face and the shaft carries the steering arm.
Every unit is assembled to order, pressure-tested before shipment, and quoted against your mounting drawing rather than off a stock list.
Sizes in the HMR2 range
Pick the size from your required output torque, then confirm rotation, mounting and shaft on the model page. Sizes without a page are quoted on request.
How the HMR2 order code works
Pattern: HMR2-{spec}-180-FT-{output}-{valve}. Worked example: HMR2-095-180-FT-1F-NV.
| Mounting | FT — Foot |
|---|---|
| Output shaft | 1F / 2F |
| Valve options | NV / CB / CS |
| Rotation | 180° |
HMR2 is rated at 210 bar continuous; peak pressure and flow at the actuator are checked against your circuit. 180° is the standard rotation on HMR2. A 360° build is quoted only after engineering confirmation.
What this range is compared with
Across the HMR2 sizes we hold comparable references for 5 Helac models, 5 HKS models, 5 Moveco models, 5 Sungji models. These are torque-class references used to route an enquiry, not validated substitutions — mounting pattern, shaft and ports are confirmed against your unit before quoting.
Other HMR series
Same helical design, different mounting interface and pressure rating. If your bracket does not match HMR2, one of these usually does.
HMR2 questions
What is the difference between HMR2 and the other HMR series?
HMR2 is the foot-mount range: steering and positioning duties on mobile equipment, where the housing bolts down onto a flat bracket face and the shaft carries the steering arm. The series is defined by the mounting interface and the pressure rating, not by torque alone — HMR2 is rated at 210 bar with 180° rotations. Other HMR series cover the same torque band with a different mount, so the machine bracket decides which one applies.
How many sizes does HMR2 cover?
7 sizes, from HMR2-050 at 508 Nm to HMR2-580 at 5,870 Nm. Every size is built to order against the same housing design, so the torque step between sizes is fixed and you pick the step that covers your load with margin.
Can HMR2 replace another make's actuator?
We supply HMR2 as an alternative where the torque class and mounting interface line up, but we do not claim a verified drop-in for any other make. The comparable references we hold for this series are Helac (5 models), HKS (5 models), Moveco (5 models), Sungji (5 models); mounting pattern, shaft and port details are confirmed against your unit before quoting.
Send the torque, angle and mounting drawing
We confirm the HMR2 size against your load and bracket, then quote the build and a delivery date.
