Detailed Applications

Industry-Specific Use Cases

  • Mining. Crushers, conveyor systems, and drilling rigs requiring bearings to withstand shock loads and abrasive environments.
  • Motors & Gearboxes. High-precision alignment for electric motors and reducers to minimise energy loss.
  • Heavy Machinery. Excavators, cranes, and hydraulic systems demanding high radial/axial load capacity.

Usage Scenarios

Operational Best Practices

  • Installation. Use hydraulic tools for mounting to avoid uneven stress distribution.
  • Lubrication. Apply lithium-based grease (NLGI Grade 2) at 30% of bearing cavity volume.
  • Maintenance. Monitor vibration levels monthly; replace if peak velocity exceeds 4.5 mm/s.
