NSK 23028CDKE4 Spherical Roller Bearing, Tapered Bore, Pressed Steel Cage, Metric, 140mm Bore, 210mm OD, 53mm Width, 1600rpm Maximum Rotational Speed, 160738lbf Static Load Capacity, 94420lbf Dynamic Load Capacity

This NSK 23000 Series spherical roller bearing has a steel cage, a CN radial clearance, an outer ring with lubrication groove and three oil holes, and a 1:12 tapered bore suitable for applications that support radial and oscillating axial loads, such as in compressors and fans. The two-piece pressed steel cage has high wear resistance, spaces the rollers for even load distribution, and prevents contact to reduce friction, vibration, and noise. The bearing's 1:12 tapered bore compensates for flexing shafts and fits tapered shafts. This bearing has a "Light" rating and two rows of symmetrically arranged rollers oriented on a concave raceway, which allow self-realignment and compensate for static and dynamic alignment errors. This bearing 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.

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.
