Product data & tolerance details at a glance

Bearing tolerances

Roller bearing tolerances guarantee interchangeability. The DIN 620 standard specifies dimensional and running tolerances. Bearings are usually produced in the PN tolerance class, but the remaining tolerance classes can be manufactured and delivered upon request or may be chosen depending on the case of application.
