Unità cuscinetto a sfere
Description
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. It has an inner ring extended on both sides and is locked onto the shaft by a SKF ConCentra locking, creating a true concentric tight fit, and setting the correct internal clearance within the bearing, and making it easy to mount.
- Strong
- Ready to mount
- Lubricated and sealed bearing
- Quick locking onto the shaft
- Cost-effective
