Abstract
A bearing block has a central hub with a pair of circular grooves near the sides of the hub. The grooves define an inner ball race and also define an outer ball bearing retaining lip. A ring-shaped sheave is disposed around the hub and has a pair of recesses in the sides, which define an outer bearing race and a thrust bearing race. Ball bearings are snap fitted into the races over the lips, such as that the bearings are self-contained in the assembly.
