Spherical roller bearing, 23022 CA/W33

Model Number: 23022 CA/W33 Brand Name: NXZ Key Specifications/Special Features: Spherical roller bearing:Spherical bearing is composed by an inner ring with a double raceway and an outer ring with spherical surface, the outer raceway center is in accord with shaft center, all having self-aligning function, which can compensate the mounting error between the shaft and bearing seat and the outer ring inclination caused by shaft deflectionThey can carry large radial load and could also supports any directional axial load but not pure axial loadIn particular, they are suitable for the applications with heavy load or vibrationStructures:20m000C type is adopting spherical symmetrical rollers, no fixed ribs on the inner ring, there are also two rows of independent solid cagesThis type of bearings is especially suitable for the applications with high speed rotation
20,000CA 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:
Tolerance of spherical roller bearings is class 0 and class 6
Tolerance value is available in section rolling bearing tolerance
Radial clearance of spherical roller bearing is listed in table 2 and 3
Dynamic equivalent radial load:
When F_a/F_r≤e, P_r=F_r+Y₁F_a
When F_a/F_r>e, P_r=0.67F_r+Y₂F_a
e, Y₁,Y₂ factors can be found in the table of bearing dimensions
Dynamic equivalent radial load:
P_0r=F_r+Y₀F_a
Y₀ factors can be found in the table of bearing dimensions
