Pillow Block and Flange Bearings
Pillow Block & Flange Bearings
Pillow block bearings, flange bearing units, bearing blocks, and take-up bearings units all consist of a housing with a bearing mounted in it. They are available in a variety of materials, mounting configurations, and various bearing features. Each mounted unit, including a mounted bearing, acts as a system to position the bearing securely for reliable operation.
Pillow Block Bearing Types
Insert Bearings For Mounted Bearings
AST offers two types of insert bearings designed for use in mounted bearing units. Simplistically, they are divided by size with the smaller, miniature insert bearings called "collar clamp ball bearings" and the larger ones called the ER Series insert bearings:
- Two Bolt Pillow Blocks
- Two Bolt Flanges
- Four Bolt Flanges
- Flangette Series
- Three Bolt Flanges
- Tapped Base Pillow Blocks
- Take Up Unit Bearings
- Collar Clamp Ball Bearings
- ER Cartridge Ball Bearing Inserts

Flanged Mounted Block Bearing Units
While other configurations are available from AST Bearings upon special order, the most common flanged mounted block bearing units are either two-bolt or four-bolt designs. Small two-bolt designs are commonly called flangettes but are of a totally different construction and design to the heavier duty Two-bolt flange series.

Axially Opposed Mounted Bearing Units
While the flanged mounted bearing units above have the axial/shaft perpendicular to the mounting surface, the units below have the shaft running parallel to the mounting surface. Click on each of the series below to learn more about each type:
