The proper adjustment of the two bearings in the hub assembly is one of the most important aspects of the installation process. Excessive tightening of the adjustment nut, otherwise known as excessive preload, can cause the type of rapid deep spalling shown in these pictures.

The cup is comprised of the outer ring and the cone assembly consists of inner ring, rollers, and cage. This bearing construction accommodates combined loads and provides low friction during operation.
