22300CA/W33 Spherical roller bearing Designs:

 C     Features a stamped steel cage and stengthened symmetric roller.As a second generation design,these bearing designs are optimized to offer considerably higher load ratings than conventional designs for a broad range of application and long service life.

 CA  The alternative design of the second generation,these bearings feature a precision-machined brass cage and strengthened symmetric roller and are equivalent to C design in load rating.They are used to exchange with C design,partticularly for large sizeds.

Application: 

       22300CA/W33 Spherical roller bearings with two spherical roller, a common concave spherical outer ring raceway, inner ring with two bearing axis tilted at an angle concave raceway, outer ring raceway curvature center and bearing center line. Spherical roller bearings are self-aligning, can compensate concentricity error resulting from shaft and bearing housing misalignment or shaft deflection deformation,. Kind of bearing in addition to radial loads, but also bear two-way axial load and their combined load, the larger carrying capacity, but also has good resistance to vibration, impact resistance.

    22300CA/W33  Spherical roller bearings are mainly used in the Medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, deceleration devices, and material handling machinery and industrial machinery stee, mining, paper, shipbuilding, textile machinery, mill, power and other industries of various machinery and equipment, machinery industry, the most widely used type of bearings.
