P2B 107-SRB-CLH
Pillow block roller bearing unit, two-bolt, SKF ConCentra lockingPillow (plummer) block roller bearing units and take-up roller bearing units consist of a spherical or tapered roller bearing mounted in a non-split housing that can be bolted to a support surface. This variant has a spherical roller bearing, a two-bolt base and SKF ConCentra locking, creating a true concentric tight fit, and setting the correct internal clearance within the bearing. The units are sealed and lubricated and ready to use. This bearing unit covers a wide range of requirements, in inch dimensions.
- Ready to mount
- Robust
- Factory lubricated and sealed
- Quick mounting
- Long service life
