HELAC SOURCING
L10-3.0-M-RF-360-S1-C-H Rotary Actuator
The L10-3.0-M-RF-360-S1-C-H is a compact 360-degree, rear-flange (RF) helical rotary actuator in the Helac L10-3.0 class, rated at 3000 psi (about 207 bar) and recorded in connection with RESEMIN drilling equipment. The reference nameplate confirms the full code L10-3.0-M-RF-360-S1-C-H; no separate machine OEM part number is published for it, so it is identified by the actuator model code. HM provides technical selection and sourcing / alternative-supply support and confirms the exact build, ports and mounting against your actuator nameplate before quotation; we do not promise stock, lead time or a pre-verified interchangeable unit from the code alone.

HM Model Reference
HMR3-030 — HM's closest model in the 340 Nm class
This reference sits in the 340 Nm class. The closest HM model is HMR3-030 — Helical, L10-style compact front flange — matched on torque class only. The left column repeats what this reference's own record states, reproduced as published; the right column is HM's own rating. The table shows what carries over and what still has to be checked on your unit.

Left column: this reference's own published figures, reproduced as recorded. Any field the record does not establish is marked “Not verified” and is never filled from HM data. Right column: HM's own rating at HM's stated pressure. Confirm both against the unit nameplate and mounting drawing before ordering.
What carries over
- HM torque class (340 Nm) at HM's 210 bar rating.
- Helical, L10-style compact front flange architecture.
- Rotation: 180/360° available on the HMR3 series. A 180/90 code is a 180° unit with the stop set at 90°, not a separate build.
What has to be verified
- Shaft / output flange interface and spline.
- Mounting bolt pattern and pilot register.
- Port size and position, plus valve arrangement (NV / CB / CS).
- Overall envelope and tie-rod clearance.
Comparable performance based on rated torque class for engineering comparison. The mounting interface must be confirmed by our engineering team before quotation.

Code anatomy
What each part of this code means
Every segment below is read from the manufacturer’s published ordering key. Where a segment is not published, we say so instead of guessing — those are the ones to confirm from the tag or the drawing before ordering.

L10 series
| Segment | Field | What it tells you |
|---|---|---|
| L10 | Series | L10 series — frame size and mounting family |
| 3.0 | Model size | Size 3.0 — rated drive torque is set by this number (thousand in-lb class in the L/T key) |
| M | Measurement system | Metric system — metric threads, BSPP ports |
| RF | Housing / mounting | Rear flange |
| 360 | Rotation | Standard 360° rotation |
| S1 | Shaft / flanges | Cantilever — shaft flange only (single) |
| C | Valve | Counterbalance valve fitted |
| H | Seals and bearings | Standard seals and bearings |

What the 360° sweep changes on this build
A full-turn build: the output sweeps a complete revolution. The hose loop and its clamping have to survive the whole sweep, which is why a full-turn unit is checked as a hose-routing question as well as a torque question.
- Check the hose loop clears the housing through the full revolution, not just at the rest position.
- Confirm the duty actually needs a complete turn — a half-turn build of the same size is the usual choice where it does not.
- Rotation stops, if the machine has them, sit outside the actuator and still have to be checked.
When this sweep is the right build
- Duties that genuinely index through a full revolution — rod handling, turret positioning, continuous swing.
- Linkages where the return path is part of the cycle rather than a reversal of the same half turn.
- Machines already built around a full-turn hose loop, where a half-turn unit would leave the routing over-travelled.
Confirming the sweep on the machine
- Turn the linkage through a full revolution by hand and watch the hose loop — a unit that binds at three quarters of a turn is a routing problem, not a torque problem.
- Check whether the machine has an external rotation stop; if it does, the sweep on the tag is not the limit the linkage actually uses.
How the sweep sits in the order code
The sweep is the fifth segment of the code. Going to the half-turn build of the same size changes that segment and the internal stop tube; flange, shaft and valve stay as they are. Where a machine only needs two positions, the half-turn build is the shorter hose route and the smaller envelope.
Where these two builds get mixed up
- A full-turn unit is sometimes quoted where the linkage only swings half a turn, which over-travels the hose loop for no benefit.
- If a full-turn unit will not pass a quarter or half turn under load, the cause is usually hose routing or an external stop, not the actuator.

These builds sit in the same torque class as the unit on this page. Same class does not mean interchangeable — the mounting interface, shaft and port arrangement are confirmed against your tag or drawing before quoting.

Questions
Frequently asked questions
What does the L10-3.0-M-RF-360-S1-C-H replace?+
It is the original Helac model code for a helical hydraulic rotary actuator providing 360° rotation. HM provides sourcing and alternative-supply support for this reference; it is not assumed to be an original Helac part or a pre-verified interchangeable unit, and the configuration is confirmed against your actuator nameplate and drawing before we quote. It is listed by RESEMIN. HM can source or arrange alternative supply for this reference; mounting dimensions, shaft, ports and the exact configuration are checked against your unit and drawing before any alternative is recommended.
Does RESEMIN publish an OEM part number for the L10-3.0-M-RF-360?+
No separate machine OEM part number is published in the available reference; the unit is identified by the actuator model code L10-3.0-M-RF-360-S1-C-H (the reference tag is rated 3000 psi). Order or enquire using that full code, and send a nameplate photo so we confirm the exact build.
Can HM supply an L10-3.0-M-RF-360-S1-C-H for RESEMIN equipment?+
We offer selection and sourcing / alternative-supply support for this compact 360-degree rear-flange unit. We do not claim a verified drop-in from the code alone; send the nameplate and, if available, a mounting drawing and we confirm rotation, rear-flange mounting, shaft and ports before quoting.
Why is the exact HM model and price not shown?+
We confirm the HM model per inquiry after verifying the interface and operating parameters with you. This avoids shipping a part that looks right by model name but differs in mounting or rotation. Price is provided with that confirmed quote.
