It is very important to comprehensive grasp of the bearing using conditions when choose a suitable bearing.
3. The running speed of the bearing
Bearing limit speed not only decided by bearing type but also the bearing size, maintains type, precision grade, load conditions and lubricating way, therefore, we must consider these factors when we choose bearing types. The following bearings are mainly for high speed rotating: Deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings.
4. Bearing rotation precision
Required rotation precision of the bearing type,such as spindle, burning steam turbine and control machines require high rotation precision respectively、 high speed and low friction, then we should choose above 5 levels the precision bearings. Generally use the following bearing: deep groove ball bearings, contact ball bearing, cylindrical roller bearing.
