SKF F4B 203-FM Ball Bearing Flange Unit, 4 Bolts, Eccentric Collar, Regreasable, Contact Seal, Cast Iron, 2-3/16" Bore, 5-1/8" Bolt Hole Spacing, 9800lbf Dynamic Load Capacity

The SKF F4B-FM series ball bearing flange unit has a cast iron housing with four bolt holes, contact seals, and eccentric collar. It is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The housing is made of cast iron for rigidity and vibration damping, and is equipped with a grease fitting on the outer surface for reapplying lubricant. The SKF YET 2 series double-sealed, deep-groove ball bearing insert in the housing accepts radial, thrust, and combined loads and has an extended inner ring on one side for increased shaft support. Its inner and outer rings and balls are made of high-grade carbon-chromium steel for durability and resistance to deformity. This self-aligning bearing has a convex sphered outer surface that compensates for misalignments. Seals on both sides of the bearing retain lubricant applied at manufacture and help protect against contaminants. The bearing has an eccentric (asymmetric) self-locking collar that fits over one side of the inner ring extension to lock the collar on the shaft. A setscrew further secures the bearing. This locking type is suitable for applications where the shaft rotates in a single 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.
