Tapered roller thrust bearings are designed to to carry axial loads with no radial load carrying capacity. They comprise of a shaft washer, a housing washer, and a roller and cage assembly and are separable. These bearings have raceways on the face the washers.
The shaft and housing washers and the roller and cage thrust assemblies of tapered roller thrust bearings with cages can be mounted separately.
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 (fig. 1).
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 SKF 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.
