Dec 21,  · ABEC standards, developed by the AMBA, are important bearing precision specifications that indicate 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.

286 and JIS B 0401 (dimension tolerances and fits). Accordingly, bearing fits are determined by the precision (dimensional tolerance) of the shaft diameter and housing bore diameter. Widely used fits for various shaft and housing bore diameter tolerances, and bearing bore and outside diameters are shown in Fig. 7.1.
