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.
