ABEC Tolerances -Bearing Grades of Precision |
Grades of Precision The ABEC scale is a system of rating the manufacturing tolerance of precision bearings. The system was developed by the Annular Bearing Engineering Council (ABEC), a division of the American Bearing Manufacturers' Association ABMA). The ABMA was formerly known as the Anti-Friction Bearing Manufacturers' Association. Bearings rated under the ABEC systems are typically called "precision bearings", with a rating or class from 1 to 9. ABEC 1 meets a looser tolerance and ABEC 9 meets high precision tight bearing tolerances. ABEC class is not to be confused with radial play, which is discussed under that section of our website. |
