The tapered roller bearing design is unique in that it combines the spherical roller bearing’s spherical alignment capability with the unrestricted axial displacement capability of cylindrical roller bearings. It can also have a smaller cross-sectional area, a feature normally associated with needle roller bearings.

This type of bearing has a wide range of applications in radial loads. Used exclusively as a non-locating end bearing, this bearing works ideally because it combines self-aligning and axial displacement capability, opening up new ways to save space, reduce weight and lower production costs. By deliberately causing relative axial displacement of the inner and outer rings, the radial internal clearance of the bearing can be accurately set.
