HELAC ALTERNATIVE
T20-60-E-FT-220-S1-C-H Rotary Actuator
Alternatives & cross-reference · 220° · 6,780 Nm at 207 bar
Looking for an alternative to the Helac T20-60 rotary actuator? This page covers the 220° foot-mount catalog configuration of the T-series dual splined-output-shaft build, with a rated output torque of approximately 6,780 Nm at 207 bar. HM can help review your unit tag, mounting drawings and operating requirements before proposing a suitable solution.
Independently supplied alternative — not an original Helac part. Configuration and fit are confirmed against your unit tag and drawing before ordering.

Questions
Frequently asked questions
What does the T20-60-E-FT-220-S1-C-H replace?+
T20-60-E-FT-220-S1-C-H is a 220° Helac L-series helical rotary actuator configuration derived from the Parker/Helac HY34-1001 ordering key and Helac T-series catalog, p. 18. 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 T20-60-E-FT-220-S1-C-H a confirmed factory order code?+
This T-series configuration is derived from the Parker/Helac HY34-1001 ordering key (T20-60 frame, T series with dual splined output shafts, E English/SAE, FT mount, 220° rotation, S1 single/cantilever flange, C counterbalance valve, H standard seals & bearings) and the published T-series performance data. It is a catalog configuration assembled per the ordering rules rather than a code independently verified from a nameplate; the exact build is confirmed against the Helac selection sheet, the original unit tag and the mounting drawing before we quote.
Why does the T20-60 reference data show 200° while this code is a 220° build?+
The published T-series performance table lists the T20-60 at a 200° standard angle, whereas the controlled order-code cross-reference assigns the complete code T20-60-E-FT-220-S1-C-H at 220°. This page uses the angle written in the complete order code. Please confirm the required rotation against your unit tag and mounting drawing, and we verify the exact build before quoting.
Can I use the Sungji SRS-150 as a direct replacement?+
The listed alternative is at a similar published torque level, but it 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 it is a suitable option for your machine.
What is special about the T-series dual splined shaft build?+
The T series uses two splined output shafts for straddle mounting, so the published moment figure is the straddle (double-support) rating rather than a cantilever value. Send your tag code and mounting drawing and we confirm the shaft, flange, ports and rotation against the available T-series builds 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.
