Tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and require little axial space.

Features and benefits
Separable design
The shaft and housing washers and the roller and cage thrust assemblies of tapered roller thrust bearings with cages can be mounted separately.
Low friction
The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear.
Long service life
Depending on the design, crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment compared with conventional straight raceway profiles.
Enhanced operational reliability
The surface finish on the contact surfaces on the rollers and raceways supports the formation of a hydrodynamic lubricant film.
High load carrying capacity
The rollers incorporated in tapered roller thrust bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution and enables the bearings to accommodate heavy axial loads.
