This Spyraflo pillow block bearing has an aluminum housing and a needle bearing insert with a 10-millimeter bore diameter. It is suitable for supporting hardened shafts that carry radial loads, such as in material handling. The one-piece bearing housing has a flat square foot to help accurately align the housing and has two mounting bolt holes. The bearing insert has a cage that spaces the needle bearings for even load distribution and reduction of friction, vibration, and noise. This bearing allows self-realignment of up to 5 degrees and compensates for static and dynamic alignment errors, it has an operating temperature range of -22 to 212 degrees F, it is permanently sealed and lubricated to help extend service life, and it has integral lip seals to retain lubricant and protect against contamination. This needle bearing pillow block is suitable for use in material handling applications, such as conveyors.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.
