Ball Bearings ABEC Standard Tolerances Data - Engineers Edge

Appliions should only require ABEC 1 or ABEC 3 ball bearings. When highly precise position is required, ABEC 5 or ABEC 7 ball bearings should be specified. The ABEC scale is an industry accepted standard for the tolerances of a ball bearing.

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.

ABEC scale - Wikipedia

Bearings not conforming to at least ABEC 1 cannot be classified as precision bearings as their tolerances are too loose. The scale also works as a guide for consumers to make informed decisions about the type of bearing they desire, despite not knowing factors related to materials, manufacturing, and performance.

Abec vs. Skate Rated™ - Support - Bones Bearings

High precision and small tolerances are required for bearings to function at very high RPM, in products like high speed routers that must spin at 20 to 30,000 RPM. In an appliion like this, an ABEC - 7 or 9 bearing rating may be appropriate. However, a skateboard with 54mm wheels turning 20,000 RPM will be traveling about 127 MPH!
