Description:
Link-Belt FCB22448H Spherical Roller Bearing Piloted Flange Unit, 4 Bolt Holes, Relubricatable, Non-Expansion, Cast Iron, Spring Locking Collar, Inch, 3″ Bore Diameter
Cast iron flanged housing with a pilot extension for accurate location and increased stability
Double-row, self-aligning spherical roller bearing compensates for misalignments and supports heavy loads
Floating labyrinth seals on both sides of the bearing keep lubricant in and contaminants out
Spring-locking collar for securing the bearing onto the shaft
Grease fitting on the housing for reapplying lubricant
This Link-Belt FC-B22400H series 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.
Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.
