ABSTRACT:
A prestressed roller bearing and method of assembly whereby the inner race, plurality of roller elements, and outer first assembled in an unprestressed manner. Then a tapered collar is inserted into the inner race, stretching the inner race to prestress the roller elements. This final assembly can be tested in the factory. Then the bearing is shipped and installed onto a conventional supported shaft outside of the factory, in the manner of an unprestressed bearing without special installation procedures or shafts or equipment. This provides a ready-to-mount prestressed roller bearing, factory tested and standardized, without damage from press-fit assembly of the inner race into the roller elements.
