Bearings for mining applications are ultra-rugged, highly sealed components specifically engineered to endure extreme shock loads, heavy vibrations, and relentless abrasive dust in continuous, 24/7 operating conditions.
Common Specifications
- Material: 8620 case-carburized steel – crack-resistant core, hard wear surface; through-hardened options for lower-impact applications.
- Heat stabilization: Up to +150°C; high-temp variants available.
- Clearance: C4/C5 standard – accommodates shaft growth and housing expansion.
- Cages: Machined brass, pressed steel, or PEEK – selected per speed, load, and lubrication type.
- Sealing: Triple-lip or heavy-duty labyrinth seals on mounted units; optional flinger discs and excluder rings.
- Housings: Cast steel, ductile iron, or fabricated – with corrosion-resistant coatings available.
Operational Gains
- Extended bearing life in abrasive, wet, and high-impact environments.
- Reduced unscheduled downtime – predictable maintenance intervals.
- Lower total cost of ownership (TCO) – less frequent relubrication and replacements.
- Direct interchangeability with industry-standard mounted units simplifies spares inventory.
