HMR series · compact front-flange · 210 bar
HMR3 helical rotary actuators
6 sizes from 190 to 2,825 Nm at 210 bar, with 180° / 360° rotations. The HMR3 range is built for tight mounting envelopes on aerial work platforms and small booms, where the front flange face carries the load and the body sits inside the boom section.
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 HMR3 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 HMR3 order code works
Pattern: HMR3-{spec}-{angle}-FF-1F-{valve}. Worked example: HMR3-030-180-CB.
| Mounting | FF — Front flange (standard) |
|---|---|
| Output shaft | 1F |
| Valve options | NV / CB / CS |
| Rotation | 180° / 360° |
HMR3 is rated at 210 bar continuous; the flange bolt pattern and pilot diameter decide whether it drops onto your existing bracket. HMR3 is offered in 180° and 360° as standard rotations.
What this range is compared with
Across the HMR3 sizes we hold comparable references for 5 Helac models, 5 HKS models, 4 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 HMR3, one of these usually does.
HMR3 questions
What is the difference between HMR3 and the other HMR series?
HMR3 is the compact front-flange range: tight mounting envelopes on aerial work platforms and small booms, where the front flange face carries the load and the body sits inside the boom section. The series is defined by the mounting interface and the pressure rating, not by torque alone — HMR3 is rated at 210 bar with 180° / 360° 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 HMR3 cover?
6 sizes, from HMR3-020 at 190 Nm to HMR3-280 at 2,825 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 HMR3 replace another make's actuator?
We supply HMR3 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), Sungji (4 models); mounting pattern, shaft and port details are confirmed against your unit before quoting.
