HKS SOURCING
M-DA-H-F7 70 Rotary Actuator
The HKS M-DA-H-F7 70 is a mobile-version helical hydraulic rotary actuator in HKS's M-DA-H programme (German maker). HKS uses its own bore/housing size numbers; the code is a size designation, not a torque figure and not a Helac size number, rated at about 500 Nm output torque at 210 bar. In the controlled cross-reference it sits in the ~509 Nm torque class together with: Helac L20-4.5; Moveco RP17; Sungji SRB-080-180-CN-FT-SH-N-I. 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 | 180° |
| Rated torque | 500 Nm |
| Unit weight | 12.8 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 L20-4.5 (~509 Nm); Moveco RP17 (~509 Nm); Sungji SRB-080-180-CN-FT-SH-N-I (~509 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 M-DA-H-F7 70 replace?+
It is the original HKS model code for a helical hydraulic rotary actuator providing 180° rotation. HM provides sourcing and alternative-supply support for this reference; it is not assumed to be an original HKS 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.
Can HM supply the HKS M-DA-H-F7 70?+
HM provides technical selection and a sourcing / alternative-supply route for the HKS M-DA-H-F7 70 base size. We do not keep stock and do not promise availability or lead time; the exact HKS configuration (S1/S2, rotation direction, valve and seal options folded into the FU/S9xxx code) is confirmed against your nameplate, with the factory when needed, before we quote.
Is the M-DA-H-F7 70 a one-to-one replacement for the Helac-class unit in the same torque bracket?+
They sit in the same torque class in our controlled cross-reference, but HKS uses its own bore/housing design and dimensions. We do not claim a verified drop-in or a guaranteed-compatible unit from the model number alone; rotation, mounting interface, shaft and ports are checked against your unit and drawing first.
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. HKS folds valve and seal options into the FU requirement code and the S9xxx material number; a complete HKS order code must be confirmed with HKS for each requirement (torque, rotation, S1/S2, rotation direction, valve, seal).
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 M-DA-H-F7 70?
Send the original HKS 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.
