Technical information on Tapered roller bearings

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
