Description

The Bearing Bushing (OEM 476 503 08) is a premium aftermarket replacement engineered for rock drilling and drifter rigs operating in the most demanding mining and tunnelling environments. 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 replacement, it ensures reliable fit and function while offering significant cost savings over the original.

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.
