ABSTRACT:
A hub for mounting on different sized sanitary machinery shafts and which has a cylindrical housing, at least one end of the housing having a cylindrical opening which is concentric with the longitudinal axis of the shaft and a cylindrical hub mounted within the housing opening and sealed around its circumference to the opening, the hub having a bore therein to accommodate the shaft, and, in some embodiments, a bushing mounted within the bore to allow the hub to be adapted to different sized shafts. A closure ring is fitted within a counter-bore in the hub, the closure ring and the counter-bore both being eccentric with respect to the longitudinal axis of the shaft so that counter-rotation of the closure ring with respect to the hub causes the closure ring to jam fit within the counter-bore of the hub and effect a liquid tight seal as well as preventing the hub from moving longitudinally along the shaft.
