Unità cuscinetto a sfere
Description
Pillow (plummer) block ball bearing units consist of an insert bearing mounted in a stainless-steel housing. They have a good corrosion resistance, and are suitable for applications with both constant and alternating directions of rotation. They have an inner ring extended on both sides and are locked onto the shaft by tightening a set screw on the inner ring, making them easy to mount.
- Ready to mount
- Designed for a constant and alternating rotation
- Good corrosion resistance
- Lubricated and sealed bearing
- Quick locking onto the shaft
