The link between bearing clearance and motor performance

Bearing clearance is a critical consideration when using motor bearings. If the working clearance is too narrow, the motor may overheat, and if the clearance is too large, it can lead to vibration and shortened bearing life. In addition to the bearing itself, the final assembly results also depend on the quality of the machining of the other components connected to the motor and the bearing, the assembly method, the degree of fit of the components, etc. Today we will tell you about the connection between bearing clearance and motor performance

Bearing clearance-free operation is the assembly process to achieve an ideal state, some motor manufacturers for large-size motors will use the method of adjusting the bearing clearance, but taking into account the special parts of the tolerance zone factors, the use of this method to achieve a good state of bearing clearance cost is higher. A spring element is often placed in the axial travel between the bearing cover and the outer ring of the bearing, if the use of spring element axial action to adjust the bearing also can not achieve clearance-free operation.

Motor bearings can support a specific amount of bi-directional axial forces in addition to radial loads under the conditions required by the motor. Small motors must take play into account because they use ball bearings at both ends. Medium motors use ball bearings at the non-load end and cylindrical roller bearings at the load end. Deep groove ball bearings are usually used as locating end bearings and lack axial clearance. To support heavy radial loads and have axial clearance, cylindrical roller bearings are usually used at the load end.
