Basic Info
Model No.: 22311
Product Description
Spherical roller bearing 22311 is designed with two rows of rollers, allowing them to take very heavy radial loads and heavy axial loads. There are also designs with one row of rollers, suitable for lower radial loads and virtually no axial load. Spherical Roller bearing 22311 the outer raceway center is in accord with shaft center,all having self-aligning function.
Structures
20000Ctype is adopting spherical symmetrical rollers, no fixed ribs on the inner ring; there are also two rows of independent solid cages. This type of bearings is especially suitable for the applications with high speed rotation.
20000CA are symmetric spherical rollers, there are fixed ribs on the center of inner ring, the solid cage is integrated. This type of bearings is widely applied and especially for applications with heavy load.
Cage material
Machined brass cage or pressed cage of steel sheet.
Permissible tilt angle
See Table 1.
Tolerance and clearance
The tolerance of spherical roller bearings is class 0 and class 6. The tolerance value is available in section Rolling Bearing Tolerance.
Radial clearance of Spherical Roller Bearing is listed in Table 2 and 3.
