  • False Brinelling - Home | Ball Bearings | Roller Bearings

    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 …

False brinelling can also occur when the bearings are used as spares or in a back-up system . The possible false brinelling loading modes are shown in Fig. 1 [1,2]. These modes are oscillation of tangential load ...

  • Issue 18: The Difference Between True and False Brinelling

    Roller bearings have proved to be more susceptible to this type of damage than ball bearings. This is considered to be because the balls can roll in every direction. Rollers, on the other hand, only roll in one direction; movement in the remaining directions takes the form of sliding. Cylindrical roller bearings are the most susceptible.

    2020-9-20 · The bearings themselves are a tapered needle roller type unique to BMW and therefore are a ridiculous price. Look to pay between £35 to £40 per bearing. The trouble with these bearings is they never fully rotate, just rock backwards and forwards, this can lead to brinelling. If the brinelling gets to bad then the bearing will likely seize.
