Ball Bearings ABEC Standard Tolerances Data - Engineers Edge

Ball bearings tend to have Lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races. The folLowing are Annular Bearing Engineers Committee (ABEC) for ball bearings quality classes

BEARING IN MIND: PRECISION BALL BEARING BASICS

ABEC tolerance classes are useful in bearing selection. By specifying ABEC 7, for example, the design engineer is able to pinpoint a standardized level of beanng precision. However, ABEC classes are not all-inclusive in defining bearing precision. Bearing performance and life can be affected by factors other than ABEC contded characteristics.
