Bearing Bushing

The Bearing Bushing (OEM 552 250 91) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It provides a precise, low-friction running surface that supports and locates moving components, absorbing wear and protecting the surrounding housing from damage.

Manufactured from hardened, wear-resistant alloy with precision-ground bore and outer surfaces, it maintains tight clearances and resists galling under continuous percussive and rotational load. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.

Backed by Delkom’s expertise in alternative rock drilling and drifter equipment, this part reflects the quality we export to over 100 countries. Reach out for availability, bulk pricing and technical support.
