F4BE 307-SRB-SRE
Square flanged roller bearing unit, set screw lockingFour-bolt square flange roller bearing units with Type E dimensions consist of a spherical roller bearing mounted in a cast iron housing that can support rotating shafts through walls, bulkheads or other flat surfaces. The units are shaft-ready, pre-assembled and pre-greased, for installation right out of the box. Locating and non-locating variants can be specified while the standard set screw mounting accommodates rotation in both directions. End covers are optional.
- Ready to mount
- Factory lubricated and sealed
- Long service life
- Minimal maintenance
