Pillow Blocks

Ball Bearings

Housings for Miniature Bearings. Aluminium Pillow Blocks, with fitted ball bearing, enable shafts to be positioned and retained in ball bearings without the need to accurately bore housings for the bearings in the main structure of the machine/assembly.

Bearing Block Example

Features:

  • Anodized Aluminium housing.
  • Bearing i/d (shaft) sizes of 3mm, 4mm, 5mm, 6mm, and 8mm.
  • Block has both vertical and horizontal mounting holes, for alternative mounting configurations.
  • Bearing is mounted asymmetrically on vertical centre-line, to allow choice of shaft mounting heights.
  • Pillow block bearings are supplied with zinc-plated M5 fixings for mounting via either the vertical or the horizontal mounting holes.
