Abstract: A taper bore bearing assembly permits variability in diameter of the rotating shaft. An annular cylinder is mechanically coupled to the rotatable shaft and a bearing element is in turn mechanically coupled to the annular cylinder, which includes a tapered bore so that an interior diameter of the annular cylinder decreases from one end to the other. An inner race of the bearing element includes accepts the annular cylinder. The interior diameter of the inner race decreases from one end to the other. A locking ring locks the annular cylinder to the bearing element. Holes extend radially through the locking ring. A screw thread mechanically couples with the bearing assembly, which screw thread is inscribed on an interior surface of the locking ring. Cutout sections in the screw thread are formed by the holes. Setscrews disposed in the holes hold the locking ring in place.

Abstract: A bearing housing carries a bearing in which an end of a rotary shaft is to be mounted. A safety end cap is mounted to the housing to cover the shaft end. The end cap includes a cupshaped plastic body which has a circular front rim, and a pair of metal brackets slidably mounted in slits formed in the body behind the rim. Outer ends of the brackets are bent to engage side surfaces of the housing, and the end cap is permanently secured to the housing by rivets which extend through the brackets.
