Description

Developed as a practical replacement option for hard-working drill rigs and drifters, the Rotation Bushing Assy (OEM 090 289 28) is used within the rotation and drive train. It supports loaded or moving interfaces by controlling clearance, guiding motion and reducing direct wear between adjacent components.

Typical listed applications include HL 850, subject to machine specification and configuration verification. The part supports cost-conscious maintenance strategies that require a reliable cross-reference option for professional drilling equipment. Accurate fit helps distribute load across the bearing area and maintain the intended clearance as the connected mechanism cycles under load.

Supported by Delkom’s experience in alternative rock-drill and drill-rig spare parts, this component is supplied for professional mining and tunneling maintenance worldwide. For availability, pricing and an application check, quote Delkom reference 110 100 755 and OEM reference 090 289 28.
