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:Both rotate, but only the rolling load of the load zone.The speed of rotation is also different
The conditions suggested that you choose the special occasions of spherical roller bearing vibration, bearing, money is money, delayed the progress of the project or the time is not money or cannot use money to calculate.
Q:What the structure of the code of spherical roller bearing
Select BSpherical roller bearing is 2 words at the beginning of the 5 digit!There is no bearing at the beginning of the bearing in the bearing type 29.So choose B!
Q:What is the size of spherical roller bearing 23210?
The basic code number is 00010203, representing the inner diameter of 10mm, 12mm, 15mm, 17mm, such as 6201, and the number of two digits in the back is, representing the inner diameter of 12mm3., the diameter of 20mm to 490mm, with the bearing code after the two multiplied by 5, for example,
Q:Gb/t 5859 thrust self-aligning bearing how to use?
Gb/t 5859 is the standard: GB/T 5859-2008 "rolling bearing thrust roller bearings dimensions"T
Q:Now why the wind power gear box are not spherical roller bearings, tapered roller bearings and all tend to use?
The bearing load is not the same type, spherical roller bearings are generally suitable for coarse, can withstand axial load where the radial, can withstand axial impact load, but he is not sensitive to axial impact load, and when the inner ring and stick rotation relative to the axis of the outer ring, will lead to the dynamic eccentricity, not concentric, will slide.
Q:The quality which the domestic E type spherical roller bearing is better? Hope to recommend it.
Research and development of KMR bearings, can completely replace imported bearings. High precision, long service life, to achieve first-class standards in the industry, it is recommended that you can try the Camry (KMR) bearings.
Q:22210cc/w33c4 spherical roller bearing is how much clearance?
The clearance of the bearings of each brand is almost the same, but the values are different.
Q:How about Harbin three kinds of spherical roller bearings?
three, the holder is not produced, their processing the production of precision, good performance, fully close to the parameters of the sample, the points above make this bearing can completely meet the usage.
Q:Which type of bearing is it better to replace double row self-aligning ball bearings?
Spherical roller bearings (spherical roller bearings) instead of self-aligning ball bearing is better.
Q:Why mechanical manual bearing SN series is only suitable for self-aligning ball bearings and roller bearings?
If you want to according to the common 0 kinds of bearings, like 6201, you can select the SN2 SN3 series, the two series is designed for the general category of bearing.
