Production


We manufacture our ball bearings with rolling bearing tolerances according to DIN 620, accuracy classes P0 to P2, and AFBMA Standard ABEC1 to ABEC9, in conformance with the respective ISO standards.

Assembly

Not all factors with an impact on ball bearing quality are covered by the various standards. A ball bearing's quality and functionality are guaranteed rather by special design characteristics and functional tests. The ball bearings produced by GRW excel in precisely those characteristics which are not covered by the standards, resulting in a level of quality far above that set by such standards. Compliance with these high quality requirements is verified by test methods developed by GRW itself.
