Precision double row roller bearing application

Precision double row roller bearing application:
The precision double row roller bearing has a large radial load capacity and can also bear heavy load and impact load.  And because of its self-aligning performance, it can withstand axial loads in both directions to some extent. 
Therefore, the precision double row roller bearing can be applied to large mechanical equipment, such as papermaking machinery, vibrating screen and general industrial machinery, where shaft deflection or assembly error is difficult to avoid.
The cage of sprecision double row roller bearing is made of steel plate for smaller size and brass or mild steel for larger size. 
Accuracy of precision double row roller bearing
Accuracy for the purchase of precision double row roller bearing is a factor that must be considered, and its use will also have a very important impact.  At present, the accuracy of bearings can be divided into six grades of standards.  
Of course, for bearings of different uses, there will be certain differences in their accuracy requirements. Therefore, we should choose according to the actual situation in the selection process. It should be noted that the accuracy of precision double row roller bearing is not as we think, the higher the accuracy, the better, which also depends on the actual production requirements. 
Precision double row roller bearing load
For different load needs, we must choose the corresponding bearings, otherwise it will not work properly. Therefore, in the actual production process, the different load is also a factor that needs to be considered in the purchase of precision double row roller bearing.  
Under normal circumstances, the load capacity of point contact bearings will be relatively weak, generally used for light or medium load, and for line contact bearings, in terms of carrying capacity is much stronger, suitable for heavy load requirements.
