Abstract

A bearing assembly for a motor vehicle drive train includes rolling elements, an outer race supporting the rolling elements, and an inner race rotatably supported by the rolling elements. The inner race includes a radially inner surface having a plurality of axially extending splines. The radially inner surface includes a primary chip groove formed therein that is defined by a primary cutting edge for spline cutting a mating shaft inserted into the radially inner surface. The radially inner surface further includes a secondary chip groove formed therein axially offset from the primary chip groove that is defined by a second cutting edge for spline cutting the shaft inserted into the radially inner surface.
