AbstractA bearing and stub shaft assembly for a belt conveyor or the like provides a non-rotatable connection between the stub shaft and the inner race of a bearing supporting one end of a cylindrical roller. An inner surface of a central cup in the inner race and the deformed elliptical outer surface of a hollow end of the stub shaft interfit to give a simple, non-rotational connection. At the same time, a cylindrical coil spring captured within the end of the stub shaft as it is deformed is compressed within the central cup to provide a preload to the bearing.
