Bearing Tolerances and Precision Levels | AST Bearings

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 carry the suffix “T”. The higher the nuer of the classifiion, the tighter the tolerances become resulting in higher precision of the asseled bearing.
