87750/87111

Single row tapered roller bearing, inch size
Single row tapered roller bearings, inch sizes, are designed to accommodate combined radial and axial loads and provide low friction during operation. The inner ring, with rollers and cage, can be mounted separately from the outer ring. These separable and interchangeable components facilitate mounting, dismounting and maintenance. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.

  • High radial and axial load carrying capacity
  • Accommodate axial loads in one direction
  • Low friction and long service life
  • Separable and interchangeable components
