HM Model Reference
HMR4-200 — HM's closest model in the 1,920 Nm class
This reference sits in the 1,920 Nm class. The closest HM model is HMR4-200 — Helical, L30-style heavy-duty — 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.

What carries over
- HM torque class (1,920 Nm) at HM's 210 bar rating.
- Helical, L30-style heavy-duty architecture.
- Rotation: 180/360° available on the HMR4 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.

L30 series
| Segment | Field | What it tells you |
|---|---|---|
| L30 | Series | L30 series — frame size and mounting family |
| 17 | Model size | Size 17 — rated drive torque is set by this number (thousand in-lb class in the L/T key) |
| E | Measurement system | English system — SAE/UNF threads, SAE ports |
| FT | Housing / mounting | Foot mount |
| 180 | Rotation | Standard 180° rotation |
| S1 | Shaft / flanges | Cantilever — shaft flange only (single) |
| C | Valve | Counterbalance valve fitted |
| H | Seals and bearings | Standard seals and bearings |

What the 180° sweep changes on this build
A half-turn build: the output travels 180° between two end stops. The sweep is set by the internal stop tube, so a 180° unit cannot be turned into a 360° one by changing the valve or the porting — it is a different internal assembly.
- Two positions, 180° apart — confirm the linkage does not rely on an intermediate stop.
- Hoses only travel half a turn, so a short service loop is normally enough.
- If the duty is a tilt or a quarter-turn swing, this is the sweep the linkage was designed around.
When this sweep is the right build
- Tilt and positioning linkages that only need two end positions — a bucket tilt, a boom offset, a chute flap.
- Machines where the hose run is tight: half a turn needs a much shorter service loop than a full one.
- Where a mid-position stop is not part of the function, so the two end stops are the whole travel.
Confirming the sweep on the machine
- Swing the linkage by hand to both end stops and check the travel is a clean half turn with no mid-travel detent.
- Read the stop positions off the mounting drawing rather than counting turns of the output.
How the sweep sits in the order code
The sweep is the fifth segment of the code. Ordering the same size in the other sweep changes that segment and the internal stop tube behind it; the flange pattern, the shaft end and the valve selection do not change with it. That is why a half-turn build and a full-turn build of one size are quoted as two builds rather than one with an option.
Where these two builds get mixed up
- A half-turn unit is sometimes quoted against a full-turn drawing because the size and mounting match — the sweep is the field that gets dropped in the enquiry.
- A half-turn unit cannot be re-stopped to a full turn in service; if the machine needs more travel, it needs the other build.

Questions
Frequently asked questions
What does the L30-17-E-FT-180-S1-C-H replace?+
L30-17-E-FT-180-S1-C-H is a 180° Helac L-series helical rotary actuator configuration derived from the Parker/Helac HY34-1001 ordering key and Helac L30 catalog, pp. 12 & 14. It is assembled per the catalog ordering rules rather than read from a specific nameplate, so the exact configuration and compatibility are confirmed against the original unit tag and mounting drawings; our alternative is matched only after that review. Send your tag code or a drawing and we confirm the exact build before quoting.
Is L30-17-E-FT-180-S1-C-H a confirmed factory order code?+
This configuration is derived from the Parker/Helac HY34-1001 ordering key (L30-17 frame, L30 series, E English/SAE, FT mount, 180° rotation, S1 single/cantilever flange, C counterbalance valve, H standard seals & bearings) and the published L30 performance data. It is a configuration assembled per the catalog rules, not an independently verified factory order code read from a nameplate. The exact configuration and compatibility are confirmed against the original unit tag and mounting drawings before we quote.
What is the difference between the 180° and 360° L30-17 builds?+
They share the same L30 frame and output torque (~1,921 Nm at 207 bar) but are different effective builds: the 360° unit displaces about 983.2 cm³ and weighs 45.4 kg, while the 180° unit displaces about 488.3 cm³ and weighs 34.5 kg; the straddle (double-flange) moment rating is also higher for the longer 360° body. They suit different travel, cycle-time and mounting-geometry requirements, so choose by the required rotation and confirm against the drawing rather than treating them as interchangeable.
Can I use the HKS M-DA-H F10/M-DA-H-F5 115, Moveco RR34, Sungji SRC-115 as a direct replacement?+
The listed alternatives are at a similar published torque level, but each is built to its own frame and mounting dimensions, so a similar rating does not guarantee a fit. Send us your unit tag and mounting drawing — we overlay the flange, shaft, ports and rotation and confirm whether one is a suitable option for your machine.
Which mounting styles are available for the L30-17?+
This page covers the E-FT-180-S1-C-H build. Send your tag code or a mounting drawing and we confirm the matching housing, flange and port arrangement against the available L30 mounting options.
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.
