SUNGJI SOURCING
SRS-150-220-CN-FT-DS-N-I Rotary Actuator
The Sungji SRS-150-220-CN-FT-DS-N-I is a helical hydraulic rotary actuator from Sungji (SJH, Korea); the ordering code follows the SRA/SRB/SRS family, bore size, rotation, valve, mounting and seal segments, rated at about 6776.4 Nm output torque at 210 bar. The SRS family is a fixed 220-degree, dual-spline-output, foot-mounted design. In the controlled cross-reference it sits in the ~6780 Nm torque class together with: Helac T20-60. These are same-torque-class engineering references only. HM Hydraulics provides technical selection support and sourcing / alternative-supply service for this reference. We do not hold it as a stocked SKU and do not promise stock, lead time or confirmed availability; configuration, mounting dimensions and drawings are checked on request against your actuator nameplate before any quotation.

| Product type | Hydraulic rotary actuator |
|---|---|
| Rotation angle | 220° |
| Rated torque | 6776.4 Nm |
| Unit weight | 81 kg @180° |
| Cross reference | All references below are engineering cross-references by torque class from HM's controlled multi-brand database; they are not validated substitutions. Same torque class (comparable rated output; independent housing and mounting designs - do not assume matching dimensions): Helac T20-60 (~6780 Nm). HM has no supply-verified interchange record for any of these pairings, so the highest claim we make is 'same torque class / comparable'; nothing is presented as a verified interchangeable unit. |
| Further data | Torque, pressure, port and mounting dimensions are shared with the engineering drawing on request. |
HM alternative model — confirmed on inquiry. Send us your original model number, part number or machine details and we confirm the matching configuration, specifications and compatibility, then quote. The exact HM model is not published online.
Questions
Frequently asked questions
What does the SRS-150-220-CN-FT-DS-N-I replace?+
It is the original Sungji model code for a helical hydraulic rotary actuator providing 220° rotation. HM provides sourcing and alternative-supply support for this reference; it is not assumed to be an original Sungji part or a pre-verified interchangeable unit, and the configuration is confirmed against your actuator nameplate and drawing before we quote. 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.
What does the Sungji code SRS-150-220-CN-FT-DS-N-I mean, and can HM source it?+
The code encodes the SRS family, bore size, rotation, valve/port, mounting, shaft cover and seal/standard. HM can source or arrange alternative supply for this standard build after confirming the exact configuration from your nameplate; we do not hold it as stock or promise lead time.
Does it match the Helac / HKS / Moveco unit listed in the same torque class?+
They are same-torque-class engineering references only; housings, mounts and published moment figures differ (some Sungji sizes are rated stronger). We do not claim a verified drop-in or guaranteed compatibility without checking the drawing, mounting dimensions, shaft and ports against your unit.
What information does HM need before quoting this actuator?+
Send us the actuator nameplate (brand, full model code, rotation, mounting, shaft and port details) and, if available, a mounting drawing. HM then confirms the exact configuration and advises the available sourcing or alternative-supply option. Mounting dimensions and drawings are provided on request only. Valve port (7/16-20 UNF vs G1/4), no-valve, double-flange, mounting style and special-seal variants are distinct order codes; the exact build is confirmed from your nameplate.
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.
Request sourcing
Need a source for SRS-150-220-CN-FT-DS-N-I?
Send the original Sungji model number, the Sandvik / OEM part number, machine details or a mounting drawing. We confirm the configuration and advise the available sourcing or alternative-supply option before quoting.
