Bearing Tolerances & Precision - GMN Bearing USA
How to Understand Precision Bearing Classes For ABEC precision classes, the higher the ABEC nuer the tighter tolerance of the manufactured bearing. Here is the ABEC scale in order from loose to tight: ABEC 1, ABEC 3, ABEC 5, ABEC 7, and ABEC 9.
Bearing Tolerances and Precision Levels | AST Bearings
ABMA standard 20 defines 5 classes: ABEC 1, ABEC 3, ABEC 5, ABEC 7, and ABEC 9. Instrument series ball bearings are defined in standards 12.1 and 12.2 and carry the suffix “P”. Extra thin and thin section ball bearings defined in standards 12.1 and 12.2
(PDF) Model of Rotation Accuracy of High-Speed Spindles on Ball Bearings
By using numerical method, Kim et al. 16 analyzed rotation accuracy of high-speed spindle and found that the rotation accuracy is closely related to the spindle speed and preload.

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.
