Pillow Block Ball Bearing

Linear Ball Bearing Pillow Blocks

Linear Ball Bearing Pillow Blocks featuring an aluminum alloy mount housing a linear ball bearing. Available with open bearing shells for rail-supported shafts or closed bearing shells for full shaft stability, they come in single or twin sizes, with twin sizes equating to two standard pillow blocks back-to-back. The ball bearings ensure a low coefficient of friction through precision steel balls rolling on a high-quality steel shaft, while resin retainers, also called polymer cages, enhance efficiency and reduce noise by maintaining smooth ball movement.

  • Static capacity up to 1,700 lb (7,900 N), supporting heavy loads
  • Dynamic capacity up to 850 lb (3,800 N)
  • Ball Bearings provide a low coefficient of friction
  • Resin retainers for efficiency and reduced noise
