ABEC 1 bearings 7 mm diameter

A.B.E.C. is the acronym of ABEC, the committee linked to the Friction Bearing Manufacturers Association, an industrial group that sets the precision levels of ball bearings. ABEC is therefore a system for classifying the construction tolerance of precision bearings.

Bearings classified with the ABEC system are usually called "precision bearings", and are marked with an odd number from 1 to 11, with the highest number assigned to bearings built to a better standard of accuracy ..

It's not true that higher ABECs go faster! Greater ABECs imply only greater constructive values, in practice the ABEC only informs us about the safe operating margins guaranteed by the manufacturer for a given bearing.
