  • Preload, clearance, and stiffness | SKF

    Universally matchable bearings and matched bearing sets are manufactured pre-set in different preload classes to meet varying requirements regarding rotational speed, rigidity, and operating temperature. The amount of preload depends on the bearing series, the contact angle, the internal geometry, and the size of the bearing and applies to bearing ...

  • Bearing preload | SKF | SKF

    Single row angular contact ball bearings are generally mounted as sets, in a back-to-back (fig. 1, fig. 2) or face-to-face arrangement that is normally subjected to an axial preload. The preload is produced by displacing one bearing ring axially, relative to the other ( fig. 1 , fig. 3 ), by an amount corresponding to the desired preload force or by springs ( fig. 2 ).

  • Selecting preload | SKF | SKF

    Spring loading is also a common method of applying preload to angular contact ball bearings in high-speed grinding spindles. The method is not suitable for bearing applications where a high degree of stiffness is required, where the direction of axial load changes, or where undefined peak loads can occur.

  • Preload, clearance, and stiffness | SKF

    An individual single direction angular contact thrust ball bearing cannot be preloaded until a second bearing provides location in the opposite direction. SKF single direction bearings are universally matchable as standard and are manufactured pre-set to two different preload classes: Class A, light preload. Class B, moderate preload.
