Tapped Base Pillow Blocks

Tapped base pillow block mounted bearing units are designed for radial loads acting in the direction of the support surface. The primary feature of these units is their narrow overall width. All units have the ability to be adjusted for static misalignment which helps the bearings run cooler.
