Abstract

A radial roller bearing, in particular a single-track ball roller bearing, which has an outer bearing ring with an inner groove track, an inner bearing ring with an outer groove track and ball rollers, which are disposed parallel to one another and held in a peripheral direction at even distances from one another by a plastic bearing cage, that roll between the bearing rings in the groove tracks. Each roller has two lateral surfaces that are flattened symmetrically from a spherical base form and a defined axial tilting clearance. The cage has two axially separated, pocketed cage halves which can be assembled in a positive-fitted, form-locked or integral fashion by opposing connecting elements.
