Bushing

Developed as a practical replacement option for hard-working drill rigs and drifters, the Bushing (OEM 550 511 66) is used within the rotation and drive train. By maintaining the working clearance at a loaded interface, it helps reduce metal-to-metal wear and supports more consistent movement.

Accurate fit helps distribute load across the bearing area and maintain the intended clearance as the connected mechanism cycles under load. Application data associates this reference with HFX5T and HLX 5T; configuration and serial-number checks are recommended before purchase. The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment.
