Abstract
A bearing block has a sheave rotatably mounted between a pair of side plates. A plurality of exposed ball bearings are mounted in the side plates for bearing engagement with the sides of the sheave. The ball bearings can circulate and are either provided in a circular groove or in arcs having a ball return channel connected between the ends of each arc. Location of thrust bearings in the side plates allows for reduction in mass of the sheave and increased space for main bearing capacity.
