Single Row Tapered Roller Bearing

Engineered for performance and precision, single row tapered roller bearings are ideal for handling combined radial and axial loads with minimal friction. Their design allows the inner ring—along with the rollers and cage—to be installed separately from the outer ring, making assembly, disassembly, and maintenance remarkably straightforward.

Thanks to their separable and interchangeable components, these bearings offer exceptional versatility. When mounted in pairs with preload, they provide a rigid and stable bearing arrangement, perfect for demanding applications.

Key Advantages:

  • High capacity for both radial and axial loads
  • Supports axial forces in a single direction
  • Designed for low friction and extended service life
  • Separable, interchangeable components for easy installation and maintenance
