P4BE 215-SRB-CRE
Roller bearing unitPillow (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. The units are sealed and lubricated and ready to use. This assortment of units covers a wide range of requirements, in metric and inch dimensions.
- Ready to mount
- Factory lubricated and sealed
- Quick locking on the shaft
- Long service life
- Easy to replace
