Double Row Spherical Bearing for sand blasting machines 21308

Spherical Bearing for sand blasting machines
Quantity:
  • 21308
Product Description
21300 Series spherical roller bearing has a high-capacity steel cage, a CN radial clearance, P5 precision, an outer ring with center lubrication groove and three oil holes, and a round bore suitable for applications that support high radial and oscillating axial loads, such as in light rail wheel sets. Its rollers, cage, and rings are made from low-oxide vacuum-melted high-carbon chrome steel for increased wear and fatigue resistance and higher limiting speeds, and it conforms to Deutsches Institut für Normung (DIN) P5 precision standard for performance within a narrow range of variation. The steel cage has high wear resistance,spaces the oversize rollers for even load distribution, and prevents contact to reduce friction, vibration, and noise. The bearing's round bore fits conventional cylindrical shafts. This bearing has an "Extra Heavy" 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 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.
