Roller bearing piloted flanged units for inch shafts

Spherical roller bearing flange cartridge unit has a cast iron housing with four bolt holes, floating labyrinth seal, and spring-locking collar. This non-expansion type bearing unit is designed for mounting onto bearing surfaces perpendicular to the shaft axis. This ready-to-mount flange cartridge unit has a one-piece housing made of cast iron for rigidity and vibration damping. The housing has a powder coating for corrosion resistance, a grease fitting on the outer surface for reapplying lubricant, and a machined mounting surface for increased stability. A cylindrical pilot extension on the back face provides accurate placement in the mounting surface bore during installation, and increases stability during operation. The double-row spherical roller bearing in the housing has a large roller complement to support heavy radial, shock, and combination loads. It has a separable outer ring, an extended inner ring for increased shaft support, and a convex sphered outer surface that compensates for misalignments. Floating labyrinth-design gap seals on both sides of the bearing retain lubricant applied at manufacture and help protect against contaminants. The bearing locks onto the shaft with a spring-locking collar and two setscrews for a positive lock on the shaft. This lock type minimizes ring distortion and vibration and is suitable for low to moderate speed applications where the shaft rotates in a single or reversing direction. Flanged bearing units are suitable for use in industrial and commercial applications including conveyors, fans and blowers, construction machinery, and processing equipment, among many others.
