Single row tapered roller bearing with flanged outer ring

Single row tapered roller bearings with flanged outer rings are easy to locate axially in the housing.

Because housing shoulders are not required, the housing bore can be manufactured more easily and cost-effectively. The bearings can accommodate combined radial and axial loads and provide low friction during operation. By combining two tapered roller bearings, a rigid bearing arrangement 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
  • Flange on the outer ring for easy location in the housing
