How is the clearance of four row cylindrical roller bearing determined?

In a given installation and working conditions, considering the inner ring with roller neck tight fit will cause clearance is reduced, the inner ring and outer ring working temperature will reduce clearance, load under the action of will lead to clearance increases, the minimum clearance required to calculate the four row cylindrical roller bearing value then again included in the effect of impact load, high speed, convenient for roll change and four row cylindrical roller bearing can be obtained under certain positive work clearance E good operating performance, increase in the volume of the iE to be E inspection tour as a benchmark of choosing bearing the original clearance. The original clearance of the four row cylindrical roller bearing can be determined by taking the closest clearance group according to relevant standards or specifications.

Application features of four row cylindrical roller bearing
1. Inner ring interference fit, outer ring clearance fit.
2. In order to improve the rolling precision of the plate, the size of the raceway of the inner ring of the four row cylindrical roller bearing is often re-ground by the same roll grinding method. Therefore, we often encounter the inner ring raceway size semi-finished products delivered.

The working clearance of four row cylindrical roller bearing must be positive and the range is wide. Generally, it is guaranteed to be within the clearance range of C2 group. The working clearance of the four row cylindrical roller bearing with high precision can be smaller, which can improve the service life of the bearing. Moreover, the roller can be grinded many times to increase the service life of the inner ring. And the outer ring regularly replace the load area, so that the bearing life greatly extended.
