7602045-TVP angular contact thrust ball bearings are separable, i.e. the washers and ball and cage assemblies can be mounted independently of each other. Although originally designed to support the rotary tables of drilling rigs, they are also suitable for other applications.

Bearing Features

• Accommodate axial and radial loads

• High load carrying capacity

• High axial stiffness

• Low friction

• High-speed performance
