Tapered Roller Bearings

Tapered roller bearings comprise an outer and inner ring with tapered raceways as well as tapered rollers in a window cage. These are single row individual bearings, usually of open design, which for technical reasons are always adjusted against a second tapered roller bearing in a mirror image arrangement. Open bearings are not self-retaining. As a result, the inner ring with the rollers and the cage can be mounted separately from the outer ring.

Tapered roller bearings can support high radial and axial loads in equal measure. Depending on the arrangement, they are suitable when precise axial guidance of the shaft is required (locating bearing function), or when the bearing arrangement must have very high axial rigidity and be operated clearance-free or under preload.

Tapered roller bearings are available as:

  • single row tapered roller bearings of standard design
  • matched tapered roller bearings (fitted in pairs in X, O or tandem arrangement, open design)
  • integral tapered roller bearings (fitted in pairs, sealed on one side, not separable).

Description

Tapered roller bearings are particularly suitable where:

  • high radial loads occur
  • high axial loads act on one side
  • combined loads must be supported (radial and axial forces acting simultaneously)
  • precise axial guidance of the shaft is required (locating bearing function)
  • the bearing arrangement must have very high axial rigidity
  • the bearing position is operated clearance-free or under preload (single bearings are adjusted against each other)
  • high running accuracy is required
  • the load carrying capacity of angular contact ball bearings is no longer sufficient and the higher speed suitability of angular contact ball bearings is not required
  • the bearings are not required to compensate misalignments
  • the design objective comprises compact, rigid and economical bearing arrangements with a high load carrying capacity
