ABSTRACT OF THE DISCLOSURE A bearing locking assembly has a sleeve that fastens an inner race ring of an anti-friction bearing of either a ball or roller design to a rotatable shaft. The sleeve is split longitudinally, enabling the sleeve to be compressed radially for slipping axially within a bore of the ring. Upon release of the compression, the sleeve expands in diameter so that a central portion of the sleeve keys the sleeve axially in place within the ring bore. The sleeve, with the ring mounted thereon, slips axially upon the shaft. External cylindrical sur- faces at the end portions of the sleeve are eccentric, and internal cylindrical surfaces at the end portions of the ring bore are eccentric. Angular rotation of the ring relative to the sleeve causes engagement of the eccentric cylindrical surfaces to tighten the sleeve about the shaft, while the concentric central portions of the sleeve and the ring maintain the ring centric relative to the shaft. The bore opening of the sleeve can be machined to receive various size shafts to adapt one size of bear- ing ring to any one of a variety of the shaft sizes. -1a-
