This Spyraflo self-aligning aluminum housing-flange unit with two bolt holes is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The housing is made of sintered aluminum for corrosion resistance and dimensional consistency, and is suitable for horizontal mounting. The self-lubricating acetal polymer bearing insert in the housing supports light loads, moderate speeds, and rotational, oscillatory, and linear motion. The bearing insert is self-aligning and compensates for +/- 5 degrees of static misalignment. This plain bearing has a maximum radial load value of 132 lbf (pounds force), a maximum speed of 1,193 RPM (rotations per minute), and operates at temperatures ranging from -40 to +180 degrees F (-40 to +82 degrees C). Designed with a regular straight bore, this bearing fits to conventional cylindrical shafts. Plain flanged bearings are suitable for use in heavy-lifting equipment, pumps, aircraft, and motors, among 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. Spyraflo manufactures bearings and bearing accessories. The company, founded in 1961 and headquartered in Peachtree City, GA, meets International Organization for Standardization (ISO) standard 9001:2008.
