Q13.What are ABEC and ISO standards?

The Annular Bearing Engineers Committee (ABEC) of the American Bearing Manufacturers Association (ABMA) establishes standards for manufacturing precision ball bearings. These standards are also accepted by (ANSI) American Standardization Institute and by international agreement for the standards developed by the International Standards Organization (ISO). The ABEC and ISO bearing standards primarily define tolerances for the ball bearing rings. These standards do not define many other aspects of the bearing such as lube, radial play, ball complement, retainer type, torque, cleanliness, etc.
