These M.C.B. type assemblies are the finest heavy duty wheels made. They are equipped throughout with standard self-aligning bearings, which take all thrust, as well as radial loads. The wide bearing spacing, make possible by the outboard style of mounting, is a decided advantage in properly distributing the combined thrust and radial loads encountered in crane operation. The outer race of one bearing on each shaft has a small amount of float to provide for expansion of the shaft. Bearings may be inspected by removing the cover plates.
