Typical DGBB Running Traces
Typical Running Traces of Deep Groove Ball Bearings
(A) shows the most common running trace generated when the inner ring rotates under a radial load only.
(E) through (H) show different running traces that result in a shortened life due to their adverse effect on bearings.
