Bearing Bushing

The Bearing Bushing (OEM 551 529 90) is a precision-made alternative spare part for rock drills and drifter equipment used in the most challenging mining and tunnelling environments. It acts as a renewable wear surface that guides and supports moving parts, taking up friction and shielding the housing from direct wear.

Made from hardened, wear-resistant alloy with accurately ground surfaces, it holds tight clearances and withstands galling under sustained impact and rotation. As an alternative spare part, it offers full functional interchangeability at a competitive cost, without compromising performance or reliability.
