Our in-stock mining special-purpose bearings are built to withstand abrasive, dusty, and heavy-load mining environments. Core models: Spherical roller bearings (22300 series) for crushers, cylindrical roller bearings (NU 300 series) for conveyors, and thrust roller bearings (29200 series) for hoists.

 

Specifications: Thickened raceways, reinforced cages (steel or brass), and abrasion-resistant steel (SUJ2 with carburizing treatment). Operating temperature range -30°C to 200°C, sealed design with labyrinth shields to prevent dust ingress. In-stock advantages: Extended wear life (≥8,000 operating hours), impact resistance, and immediate availability for emergency repairs. We support custom lubrication for specific mining conditions.
