This Rexnord KEF2300 spherical roller flange block bearing has a cast-iron housing with four bolt holes, a spherical roller bearing insert with a single setscrew locking collar and a 3" straight bore, and a light contact seal. The bearing housing is made of cast iron and has a spherical roller bearing insert for a ready-to-mount installation, and its one-piece construction provides maximum strength and rigidity. It can be used interchangeably with fixed Type E bearings. The bearing insert's double-row construction allows for both radial and thrust loads under static, oscillatory, or dynamic conditions, and for misalignment of the inner race in any direction up to 4 degrees of total misalignment. It has super-finished raceways for reduced friction and noise, an open design that allows for lubrication in place, and a C3 clearance rating that accommodates thermal expansion at higher speeds. It has a dynamic load rating of 57,750 lbf and a static load rating of 71,500 lbf. The light contact seal protects the bearing against contaminants while allowing for higher speeds, creating less drag, and generating less heat than heavy contact seals. This spherical roller flange block bearing is suitable for use in mining, construction, package handling, and other applications.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.Rexnord manufactures power transmission components under brands such as Link-Belt, Thomas, and Stearns, and water management products under brands such as VAG and Zurn. The company is headquartered in Milwaukee, WI.
