Description

Engineered to support reliable operation in harsh drilling environments, the Rotation Bushing (OEM 153 756 88) is a high-quality aftermarket component for compatible rock drilling and mining equipment within the rotation mechanism. It supports accurate guidance between mating components while controlling radial play and wear. Typical compatible references in the supplied list include DS411, DS411-C and HE 300.

Produced to controlled dimensions from application-appropriate wear-resistant material, it is intended to maintain a stable running clearance and a consistent bearing surface throughout the service interval. This is especially important under repeated sliding contact, shock loading, vibration and abrasive contamination. Proper support helps protect adjoining parts, preserve alignment and reduce uneven wear in the assembly.

This aftermarket component reflects Delkom’s focus on application-matched solutions for drilling-equipment maintenance. For ordering and cross-reference purposes, use Delkom reference 110 100 143. For stock status, bulk pricing and application support, contact the Delkom spare-parts team.
