Engineered for abrasive coal dust, moisture, continuous conveyor loads, and 24/7 operation.
Function & Product Specifications
Coal handling – conveyors, feeders, stackers, and reclaimers – demands bearings that resist abrasive dust, water spray, and continuous heavy loads. BMI offers a full range of mounted and unmounted bearings from stock, with triple-lip sealed housings for contaminant exclusion and case-carburized steel options for impact resistance. Focus is on reducing conveyor downtime and simplifying spares inventory.
Stock Housing Styles
Pillow block, 2-bolt/4-bolt flange, and cartridge units – interchangeable with major industry standards.
Common Specifications
- Heat stabilization: Up to +120°C; high-temp variants available.
- Sealing: Triple-lip contact seals on mounted units (IP6X dust protection); labyrinth and flinger options available.
- Housings: ASTM A48 Class 30 housings with 180-220 BHN hardness.
- Interchangeability: Dimensions match major industry standards for drop-in replacement.
- Stock Availability: Ready-to-ship from inventory across all housing styles and sizes.
Operational Gains
- Reduced conveyor downtime – quick drop-in replacements from stock.
- Extended bearing life in abrasive, wet, and high-load environments.
- Lower total cost of ownership (TCO) – less frequent relubrication and replacements.
- Simplified spares management – standardized housings and interchangeable dimensions.
- Predictable maintenance intervals – condition-based planning enabled.
- Faster installation – pre-assembled, pre-greased mounted units.
- Reduced lubricant consumption – sealed units retain grease longer.
