Bearing tolerances explained | Engineering360 - GlobalSpec

21/12/2018· ABEC standards, developed by the AA, are important bearing precision specifiions that indie the tolerances of a ball bearing. The ABMA issues five ABEC quality standards: 1, 3, 5, 7 and 9 — the higher the ABEC rating, the tighter the tolerances. Tolerances also change with different bearing bores and outside diameters.
