ac fan motor bearings

If motor manufacturer instructions are not available, determine the appropriate grease relubrication intervals for motors under normal operating conditions using Figure 1, which is based on information provided by NSK Bearing Corp. (Note: Grease relubrication intervals for normal operating conditions can be read as a function of bearing speed and bore. Most electric motors are designed with grease-lubricated, antifriction, rolling-element bearings. Finally the com-plete assembly is balanced and bearings are pressed on each end of the shaft. | These limit the entry of contamination greatly. 99.
