Product Description:

Specification of Spherical Roller Bearing:

- High load carrying bearings 

- High quality, long lifetime 

- Bearing factory with rich stock

- Cage: CA CC MB 

- Clearance: C2 C3 C4 C5


Dimension of Spherical Roller Bearing:

Overall dimension of bearing listed in bearing table accords to ISO015-1981       


Angular Alignment Tolerance of Spherical Roller Bearing:

Self-aligning roller bearing is designed in such a way that it is self-aligning. That means that bearing can adjust itself and angular alignment tolerance between outer rings. Under normal load and working condition and inner ring rotates, the unsymmetrical value listed in below table is allowed. Achieving completely specified value is subject to design and seal type of configured bearing.


Tolerance of Spherical Roller Bearing:

Our self-aligning roller bearing with cylindrical bore or tapered core is of common tolerance level.


Internal Clearance of Spherical Roller Bearing:

According to our standard, self-aligning roller bearing is of common tolerance level in internal clearance in its radial direction. Almost all bearings can be supplied at C3 clearance, or even higher level C4 clearance. Bearings with dimension less than common level: C2 clearance can also be supplied. Please consult first to check supply status for bearing with non-standard radial clearance (including C5). These clearance values are used for zero load testing and shaft, which remains uninstalled.


Structure of Spherical Roller Bearing:

Besides CA type, we can provide CC and MB structure for special clients. Please contact us for detail.

Q:How to eliminate the use of spherical roller bearing axial thermal expansion
Spherical roller bearing for the separable type, the inner ring and the outer ring can be installed separately, thus simplifying the installation process, especially when the rings are required when the interference fit.
Q:Spherical roller bearing and shaft concentricity of what is required
First of all, choose "C" precision bearings (B class accuracy is highest, I do not know whether the current national standard);
Q:The diameter of 50 by 110 height of 50 spherical roller bearing
Do not meet the size of the standard bearing spherical roller bearing, the thickness is 40 mm (the size of the most close to the old model, 3610), the new model 22310.
Q:22224ck type tapered bore spherical roller bearing with 22224ck/w33 cone hole and use difference roller bearings.
The difference is that the outer ring of the W33- bearing is provided with a lubricating tank and three lubricating holes. The lubricating oil can be injected into the inner part of the bearing from the outside of the bearing through the three lubricating holes.
Q:Spherical roller bearing high temperature can reach a maximum number of degrees
The thermal stability is greatly reduced and the dimensional tolerances will change. Of course, if you select a special material such as zirconia, the temperature resistance may be increased to 400. The specific working conditions need to be related to the process.
Q:At the same time spherical roller bearing and deep groove ball bearing using it
You can say what you use specific environment what equipment used in roller bearings belong to the characteristics of rolling bearing and its use is low speed and high load characteristics of deep groove ball bearing is a sliding bearing is high speed low load if there is a need to my private
Q:Ma spherical roller bearing and MB do the same price
You're talking about CA and MB. MB is expensive
Q:Spherical roller bearing installation, four corners to withstand?
When installed, the small bearings are pressed into the inner ring or outer ring by ring,Even if you press a few points, it is also three to determine a plane ah, what four angles?.
Q:Spherical roller bearing 22218TN1/w33R suffix R is what mean?
This R is not a standard suffix code, so different brands will have different interpretations. It is best to consult the brand representatives directly.SKF explanation: R outer ring with flangeKOYO's explanation: increased load capacity of self-aligning, tapered and cylindrical roller bearings
Q:Thrust roller bearings and spherical roller bearing combination, the rotation center need to coincide
The raceway of the bearing outer race is spherical shape, so the self-aligning performance is good, and the coaxiality error can be compensated.
