Cages

Depending on their series and size, single row super-precision angular contact ball bearings are fitted as standard with one of the following cages (matrix 1):
  • a cotton fabric reinforced phenolic resin cage, window-type, outer ring centred, no designation suffix (fig. 1)
  • a glass fibre reinforced PEEK cage, window-type, outer ring centred, designation suffix TNHA (fig. 2)
  • a carbon fibre reinforced PEEK cage, window-type, outer ring centred, no designation suffix (fig. 3)
  • a machined brass cage, window-type, outer ring centred, designation suffix MA

The lightweight polymer cages reduce inertial and centrifugal forces while maximizing the effectiveness of the lubricant.

Other cage materials and designs are available on request. Contact the SKF application engineering service.
