This Rexnord ZB series round flange block has a cast iron housing with three bolt holes, and setscrew locking collar. This non-expansion type bearing unit is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The one-piece, non-expansion housing is made of cast iron for rigidity and vibration damping and has a powder coating for corrosion resistance. A cylindrical pilot extension on the back face provides accurate placement in the mounting surface bore during installation and increases stability during operation. It is equipped with a grease fitting on the outer surface for reapplying lubricant. The double-sealed spherical roller bearing insert in the housing supports heavy radial or combination radial and thrust loads, and has a hardened, ground extended inner ring for increased shaft support. The inner raceways are case-carburized for high speeds, reduced noise, and high loads. This fully self-aligning bearing can accommodate dynamic and static misalignments
