Same frame and output torque, different displacement, weight, body length and straddle moment — they match different cycle-time, hydraulic-flow and mounting-geometry requirements. Select by the angle your mechanism needs, not by the model number alone.

Questions
Frequently asked questions
What does the L10-15-E-RF-180-S1-C-H replace?+
L10-15-E-RF-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 L10 catalog, p. 8. 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 L10-15-E-RF-180-S1-C-H a confirmed factory order code?+
This configuration is derived from the Parker/Helac HY34-1001 ordering key (L10-15 frame, L10 series, E English/SAE, RF mount, 180° rotation, S1 single/cantilever flange, C counterbalance valve, H standard seals & bearings) and the published L10 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° L10-15 builds?+
They share the same L10 frame and output torque (~1,695 Nm at 207 bar) but are different effective builds: the 360° unit displaces about 1,104.5 cm³ and weighs 54.4 kg, while the 180° unit displaces about 552.2 cm³ and weighs 43.1 kg. 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 90, Sungji SRA-160 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 L10-15?+
This page covers the E-RF-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 L10 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.
