Part Number: 265858867 (2658 5886 70)

2658588670 Rotary Head Gearbox (2658 5886 70)

2658588670 is a rotary head gearbox (part of the rotary head / rotation unit assembly) used on Epiroc surface drilling rigs. This mechanical transmission module transfers power from the drive system to the spindle, reducing rotational speed and increasing torque to deliver stable, controlled rotation during drilling operations.

In the rotary head assembly, the gearbox works together with the spindle, bearings, seals and housings to maintain drilling accuracy, proper load distribution and reliable performance under demanding operating conditions.

This component is typically associated with Epiroc (Atlas Copco) DM and DML series rigs.
