P4BE 315-SRB-SRH
Pillow block roller bearing unit, four-bolt, E-type, set screw locking
Pillow (plummer) block roller bearing units consist of a spherical 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
