speed

The working speed of rolling bearing mainly depends on its allowable operating temperature.Bearings with low friction resistance and less internal heat are suitable for high speed operation.When only bearing radial load, deep groove ball bearing and cylindrical roller bearing can achieve a higher speed, if bearing combined load, angular contact ball bearing should be selected.High precision angular contact ball bearing with special design can achieve high speed.The speed of all kinds of thrust bearings is lower than that of radial bearings.

Rotation accuracy

For the majority of machinery, choose a level 0 tolerance of bearing is enough to meet the requirements of the host, but on the axis of rotation accuracy have strict requirements, such as spindle, precision machinery and instrument etc., should choose high tolerance grade of deep groove ball bearings, angular contact ball bearings, tapered roller bearings, cylindrical roller bearings and thrust angular contact ball bearings.
