| Cross reference | BG00391147 is a Sandvik OEM reference for the DD321-40 turning unit. Because the underlying actuator brand/model and interchangeability have not been independently verified, the drawing and mounting dimensions are checked against your unit before any alternative is recommended. BG00391147 and BG01035613 are both recorded on the DD321-40 in the same weight class and should be distinguished by the tag rather than assumed identical. |
| 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.
