This Spyraflo self-aligning needle-roller bearing with steel flange and two bolt holes is designed for mounting onto bearing surfaces perpendicular to the shaft axis. The flange is made of steel for strength and resistance to shock. The drawn-cup needle roller bearing insert in the housing supports medium loads, high speeds, and rotational motion only. The needle rollers are retained in a cage and roll against hardened shafts that act as the inner bearing raceway. The bearing is prelubricated with lithium-complex grease. The bearing insert is self-aligning and compensates for +/- 5 degrees of static misalignment. This needle roller bearing operates under temperatures ranging from -22 to 212 degrees F (-30 to 100 degrees C). Designed with a regular straight bore, this bearing fits to conventional cylindrical shafts. Plain flanged bearings are for use in various applications such as 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.
