Pillow blocks, the most commonly used type of mounted units, provide shaft support where the mounting surface is parallel to the shaft axis. The bolt holes are usually slotted for easy adjustment during mounting.

Pillow blocks come in a variety of configurations.

  • Narrow series (V and S) are lightweight, yet structurally designed to support bearing load.
  • Premium width series (R and Y) are three times stronger for rougher environments. They’re available in two styles that fit typical applications.
  • Pressed steel and rubber pillow blocks are available for light-duty applications.
