P4BE 215-SRB-SRE
Pillow block roller bearing unit, four-bolt, E-type, set screw 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 four-bolt base, creating a stable and robust unit, and set screw locking, holding the shaft firmly against the inner ring of 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
