China Spherical Roller Bearing 232/500 CAK/W33 OH
A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.Despite what their name may imply, spherical roller bearings are not truly spherical in shape. The rolling elements of spherical roller bearings are mainly cylindrical in shape, but have a profile that makes them appear like cylinders that have been slightly over-inflated.
Spherical roller bearings are predominantly double row roller bearings with a common sphered raceway in the outer ring. Spherical roller bearings are self-aligning making them forgiving to misalignment of the shaft relative to the housing. Spherical roller bearings can handle both radial and axial loads.
The two rows of rollers allow the spherical roller bearing to carry heavy loads. Available in a wide range of ISO dimension series sizes, spherical roller bearings can often be utilized to replace other bearing types. Spherical roller bearings are also available for specialized applications, such as vibrating screens where more clearance is built in. Spherical roller bearings are available from some manufacturers with rubber seals to help reduce contamination and extend bearing life.
Spherical roller bearings are available with cylindrical or tapered bores, and can have different features such as bronze or steel retainers and with or without oil holes. Standard sizes range from 20mm (.7874) inside diameter to 1820 mm (71.6535") outside diameter. Spherical roller bearing standard series consist of: 21300, 22200, 22300, 23000, 23100, 23200, 23900, 24000, 24100.
