Roller bearing with a one-piece plastic cage

摘要

A machine roller bearing has rollers (3) and race (4, 5, 18, 24) surfaces in which clips (22) are held in position by plastic cages (8,9). The cages hold and guide both the clips and rollers The cage rim has a number of radial projections around the circumference. Under elastic bending of the plastic cage the outwardly directed radial projections bend inwards, while the inwardly directed radial projections bend outwards, placing both sets within the ring-shaped slot (5a).
