HMR3 series · spec 160 · Helical, compact front-flange family
HMR3-160 helical rotary actuator
1,695 Nm driving torque at 210 bar, 180° / 360° rotation, in front-flange mount. The HMR3-160 is 5th of 6 sizes in the HMR3 compact front-flange range, built to order 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.
It sits between HMR3-100 at 1,075 Nm and HMR3-280 at 2,825 Nm.

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 the code means
Every HMR3 unit is specified the same way. If your tag carries a different suffix, the base size is still HMR3-160.

Models customers compare with HMR3-160
These are the models that sit in the same torque class and come up in the same enquiries. They are comparable references, not validated substitutions — we confirm the mounting pattern, shaft and port details against your unit before quoting.

Comparable performance based on rated torque class for engineering comparison. The mounting interface must be confirmed by our engineering team before quotation.
What we check before quoting
On the unit
- Mounting pattern and bolt spacing
- Shaft type, spline or keyway, and length
- Port size, thread form and valve arrangement
On the machine
- Available envelope and tie-rod clearance
- Working pressure and flow at the actuator
- Rotation stops and any mechanical limits
HMR3-160 questions
What can I use in place of an HMR3-160?
We build the HMR3-160 itself to order, and where an HMR3-160 is no longer available we quote the closest HM HMR3 build and confirm the fit against your unit. We do not publish a one-to-one substitution table, because mounting pattern, shaft, port thread and valve arrangement have to match your machine, not just the torque class.
Is HMR3-160 a direct replacement for Helac L10-15?
No — we do not claim a verified drop-in for any other make. Enquiries for this torque class arrive tagged as Helac L10-15, HKS M-DA-H 90, Sungji SRA-160; we treat those as comparable references and compare rated torque, mounting interface, shaft and ports before quoting the HMR3-160 build that suits your machine.
How is the HMR3-160 order code put together?
The pattern is HMR3-{spec}-{angle}-FF-1F-{valve}. A worked example is HMR3-030-180-CB. Rotation, mount, output and valve are chosen per machine, so the code on your drawing is what we build to.
