Abstract

A bearing assembly for supporting a shaft without play, in particular for use with a steering shaft in a steering column, includes a plurality of needle-like rollers that are circumscribed by a thin-walled, split bush for elastically loading the rollers in radial direction. Fitted about the bush is an elastic ring that applies a preload on the bush and has at least one peripheral surface formed with neighboring ridges of relatively greater radial dimension and relatively smaller radial dimension in alternating relationship.
