The Ball Bearing (OEM 511 049 70) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It supports rotating and oscillating loads with minimal friction, maintaining precise alignment and smooth motion under heavy radial and axial stress.
Manufactured from high-grade hardened bearing steel with precision-ground raceways, it delivers the load capacity and fatigue resistance required for long service intervals and reduced downtime. Offered as an aftermarket alternative, it delivers full interchangeability and proven durability at a more competitive cost.
