Bearing Bushing

The Bearing Bushing (OEM 344 839 78) is a high-quality alternative spare part built for rock drills and drifter rigs working under the toughest mining and tunnelling conditions. 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.

Delkom produces premium alternative rock drilling and drifter equipment and spare parts, shipped to over 100 countries worldwide. Get in touch for stock availability, bulk pricing and technical assistance.
