  • What is Bearing Brinelling? | Rexnord

    Brinelling is named after the Brinell scale of hardness, in which a small ball is pushed against a hard surface at a preset level of force. The depth and diameter of the mark that is left indicates the brinell hardness of the surface. Brinelling of bearings comes in two types, true brinelling and false brinelling.

  • The brinelling of small ball bearings - NASA/ADS

    The brinelling of ball bearings is a subject which has had comparatively little study. Since ball bearings have found most of their applications in such things as rotating shafts, there has been little reason to study their action under static loading conditions. This research was suggested by the Fafnir Ball Bearing Company because of the increasing use of ball bearings for static loads in ...
