Description

The Roller Bearing (OEM 0509 0121 12) is a durable alternative replacement designed to perform reliably on rock drills and drifter rigs in harsh mining and tunnelling applications. It carries rotating and oscillating loads with low friction, keeping components accurately aligned and moving smoothly under heavy radial and axial forces.

Made from high-grade hardened bearing steel with precision-ground raceways, it offers the load rating and fatigue strength needed for extended service and reduced downtime. As a cost-effective alternative component, it matches the form, fit and function of the original while maintaining high reliability.
