FAG Bearings U220 Thrust Ball Bearing Seating Washer, Metric, 125mm ID, 155mm OD, 14mm Width

This FAG U2-series thrust ball bearing seating washer is for use with FAG 532- and 542-series axial deep-groove ball bearings that come with spherical housing locating washers. The seating washer, also called a support washer, is used with the spherical housing washer to compensate for initial static misalignments between the support surfaces on the shaft and those in the housing. The washer is made of a low alloy, through-hardened chromium steel for durability, heat tolerance, and resistance to deformity under heavy loads, and it can be used at operating temperatures from -30 degrees C to 150 C (-22 degrees F to 302 F). This seating washer is manufactured to PN (normal) tolerances in accordance with Deutsches Institut für Normung (DIN) 620, and it is suitable for use in various applications including machine tool drive shafts, automotive steering gears and clutches, rotary tables, outboard motor propellers, and household appliances. Specifications Dimensional and geometric tolerances DIN 620-3 (ISO 199), tolerance class PN Through-hardened steel ISO 683-17 System for creating part numbers for rolling bearings DIN 623-1Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.FAG manufactures a variety of bearings that meet International Organization for Standardization (ISO) and Deutsches Institut für Normung (DIN) standards for quality assurance. The company, founded in 1883, is based in Schweinfurt, Germany.
