Back Liner Cylinder

The Back Liner Cylinder (OEM 140 101 447) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. 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.
