Bearing Bushing

The Bearing Bushing (OEM 551 529 88) 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. Supplied as an alternative spare part, it provides direct functional interchangeability and dependable performance at a competitive price.

Delkom manufactures the world’s highest-quality alternative rock drilling, drifter equipment and spare parts, exported to more than 100 countries. Contact us for availability, bulk pricing and technical support.
