Abstract
An end cap holds an antifriction bearing on a journal at the end of an axle, clamping the inner race of the bearing tightly against a backing ring that is located around the journal. The end cap has an cross wall which extends across the end of the journal and an axial wall formed integral with the cross wall and extended over the journal to provide an abutment surface which is presented toward the inner race of the bearing. The cross wall contains bolt holes through which cap screws pass to thread into the journal and secure the end cap on the journal. The end wall possesses its thickest cross section in regions between the bolt holes and its thinnest cross section in regions generally surrounding the bolt holes. This distributes the clamping force exerted by the cap screws more uniformly over the abutment surface at the end of the axial wall.
