| Cross reference | HKS is the original actuator brand; Atlas Copco / Epiroc lists the unit under part number 3128309172. Because the precise HKS model and interchangeability have not been independently verified, the drawing, mounting dimensions, shaft, ports and rotation are checked against your unit before any alternative is recommended. |
| 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.
