Bearing Tolerances

Tolerances classes and the corresponding values for certain characteristics are specified in ISO492 (for radial bearings) and ISO199 (for thrust

bearings).

In 2014 these standards were aligned with general ISO GPS (Geometrical Product Specification) standards such as ISO1101 and ISO5459.

Normally, there are three common tolerance classes for ball and roller bearings:
