Pillow block bearing UCP211
Pillow (plummer) block ball bearing units consist of an insert bearing mounted in a cast iron housing that can be bolted to a support surface. This variant is strong and stiff, and is suitable for applications with both constant and alternating directions of rotation. It has an inner ring extended on both aspects and is locked onto the shaft by tightening a set screw on the inner ring, making it easy to mount.
Strong
Designed for a steady and alternating rotation
Ready to mount
Lubricated and sealed bearing
Quick locking onto the shaft
Cost-effective
