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.
HP-15-S-FT-180-S1-O-H
HP series
| Segment | Field | What it tells you |
|---|---|---|
| HP | Series | HP series — frame size and mounting family |
| 15 | Model size | Size 15 — rated drive torque is set by this number (thousand in-lb class in the L/T key) |
| S | Measurement system | Special / custom build (older tags use S for special) — not a standard E or M unit |
| FT | Housing / mounting | Foot mount |
| 180 | Rotation | Standard 180° rotation |
| S1 | Shaft / flanges | Cantilever — shaft flange only (single) |
| O | Valve | No valve |
| 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 HP-15-S-FT-180-S1-O-H replace?+
It is the model code for a Helac helical rotary actuator providing 180° rotation in the 27 kg class. It is listed by Sandvik under part number 76350011. Our alternative is matched to the same rotation, 27 kg class and mounting interface.
How do I know this fits my machine?+
The same actuator is recorded on the DS311, DS2710. Before quoting we confirm the mounting face, port position and rotation against the tag and a photo of your unit, so the replacement matches your exact build.
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.
