NSK 22205CE4 Spherical Roller Bearing, Round Bore, Pressed Steel Cage, Metric, 25mm Bore, 52mm OD, 18mm Width, 7100rpm Maximum Rotational Speed, 8318lbf Static Load Capacity, 8430lbf Dynamic Load Capacity

This NSK 22200 Series spherical roller bearing has a steel cage, an outer ring with lubrication groove and three oil holes, a CN radial clearance, and a round bore suitable for applications that support high radial and oscillating axial loads, such as in light rail wheel sets. The two-piece pressed steel cage spaces the rollers for even load distribution and prevents contact to reduce friction, vibration, and noise, and the cage is guided on the outer ring. The round bore fits conventional cylindrical shafts. This bearing has a "Heavy" rating and two rows of symmetrically arranged oversized rollers oriented on a concave raceway, which allow self-realignment and compensate for static and dynamic alignment errors. It has a maximum operating temperature of 392 degrees F. This roller bearing's CN (normal) radial clearance is for applications where thermal expansion does not reduce clearance. This roller bearing is intended for interchangeability and meets Deutsches Institut für Normung (DIN) standards for parts numbering, bearing dimensions, load ratings, tolerances, and clearances. It meets International Standards Organization (ISO) standards for hardening of bearing rollers and rings. This spherical barrel roller bearing is suitable for use in material handling equipment, electric generators, and machine tools.SpecificationsMain bearing dimensionsDIN 635-2Basic dynamic load ratingsDIN ISO 281Dimensional and geometric tolerances DIN 620-2, (ISO 492) tolerance class PNSteel composition for inner and outer rings and rollersISO 683-17System for creating part numbersDIN 623-1Roller 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 roller 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.NSK manufactures ball and roller bearings, linear guides, and other components for automotive and industrial applications. The company, founded in 1916 in Japan, has offices in Ann Arbor, MI, and meets International Organization for Standardization (ISO) TS 16949 and 9001 standards for quality assurance.
