Spyraflo BFM-8M-A Flange Mounted Plain Bearing, Self-Aligning Type, 2 Bolt, 8mm Bore Diameter, Delrin Acetal Plastic and Steel, Inch
This Spyraflo BFM-8M-A self-aligning acetal plastic bearing with a steel flange, two bolt holes, and an 8mm bore diameter supports light loads, moderate speeds, and rotational, oscillatory, or linear motion. The ready-to-mount lightweight steel flanged housing provides strength, resistance to shock loads, and a compact design suitable for limited space applications. The acetyl polymer (Delrin) bearing insert in the housing is self clinching for a secure fit. This self-aligning bearing compensates for static misalignment errors, and exhibits a low coefficient of friction and low stick-slip. It is approved by the U.S. Food and Drug Administration (FDA) for food and dairy applications. This flanged bearing is suitable for use in applications including printers, product handling systems, and vending machines, 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.
