P2BC 108-TPSS
Pillow block ball bearing unit with extended inner ring and set screw locking, compositePillow (plummer) block ball bearing units consist of an insert bearing mounted in a composite housing that is lightweight but robust and has excellent corrosion resistance. This variant is suitable for applications with both constant and alternating directions of rotation. It has an inner ring extended on both sides and is locked onto the shaft by tightening a set screw on the inner ring, making it easy to mount.
- Designed for a constant and alternating rotation
- Excellent corrosion resistance
- Lightweight
- Recyclable
