Abstract: A bearing assembly for a shaft including an inner ring that mounts on the shaft and an outer ring disposed concentrically about the inner ring. Ball bearings are interposed between the inner and outer rings. Fingers are formed on one side of the inner ring and they extend axially with adjacent fingers defining longitudinally extending slots. An outwardly opening notch is formed in each of the fingers to create an outwardly opening circumferential groove around the inner ring. A compressible annular locking collar is positioned circumferentially around the fingers. A fastener screw is operable to compress the fingers into locking engagement with the shaft. A first elongated locking rod extends through the locking collar and into an outwardly opening notch in one of the fingers to secure the locking collar against axial movement relative to the fingers.

Abstract: An annular locking collar for a bearing assembly mounted on a shaft. The locking collar is formed with a gap which is closeable to increase the locking effect of the collar on the bearing assembly. The locking collar includes lugs formed on the annular collar on opposite sides of the gap. Aligned smooth bore fastener passages are formed in the lugs. A headed threaded fastener extends through the fastener passages with the fastener head engaging one of the lugs and a nut threaded on the fastener engaging another of the lugs to close the gap to lock the collar on the bearing assembly.
