Regrasing interval of bearings 

By the  term  “greasing  interval”  we  mean the  number  of  working hours after  which 

the bearing lubricant has to be replaced. 

Electric motors have such a wide range of application that they must cope with many 
adverse conditions as for instance dust, moisture, vibration, temperature, chemicals, 
marine atmosphere and of course, the mounting position and loading of the driven 
machine. 

Generally we can say lubrication life is a product of time, speed and the bearing size. 
Due  to  the  impact  of  all  these  factors,  it  is  practically  impossible  to  determine  any 
exact  values  that  are  valid  under  all  circumstances.  Nevertheless  it  is  necessary  to 
provide at least some guidelines concerning greasing to the user.
