Zinc Aluminum Mini Pillow Block - Set Screw (KP)

Zinc Aluminum Mini Pillow Block Mounted Unit Bearings with Set Screw (KP) have zinc aluminum housings and chrome steel inserts. Pillow Blocks have a bearing fitted into a housing and are used when the bearing mounting surface is parallel to the shaft axis. The housing is bolted to a foundation through the holes in the base. A set screw is a type of screw generally used to secure a bearing race to a shaft. Set screws are most often headless (also called blind), meaning that the screw is fully threaded and has no head projecting past the major diameter of the screw thread. It exerts compressional or clamping force through the bottom tip that projects through the hole.
