Abstract

A bearing assembly includes at least one outer ring and an inner ring unit including first and second inner rings, the inner ring unit having a central, axial bore extending through the first and second inner rings, and a plurality of attachment bores for attaching the bearing assembly to a bearing carrier. A first plurality of roller bodies is disposed between the at least one outer ring and the first inner ring and a second plurality of roller bodies is disposed between the at least one outer ring and the second inner ring. A pin extends through the central axial bore of the first inner ring and through the central axial bore of the second inner ring, and the pin maintains a predetermined preload on the bearing assembly by holding the first inner ring in a fixed position relative to the second inner ring.
