Pillow Block Bearings

Pillow block and base-mount bearings carry radial and axial loads. They are often mounted in housings called pillow blocks, which support shafts and increase precision. The pillow block protects the bearing and contains the mounting holes while setscrews or locking collars secure the insert bearing in the pillow block. Pillow blocks compensate for mounting errors and may be split into two pieces to easily inspect and replace bearings.
