Servo Motor Repairs: Bearings Number 1 Cause of Servo Motor Failure
If your servo motor is not working properly, chances are good that the bearings are the main problem.
They may have reached the end of their useful life, especially if they are factory sealed bearings that cannot be lubricated.
Or, if you have have open bearings, they may have become contaminated, especially if your work environment is not very clean. Lubrication of the bearings, if possible, is a good way to get the most life out of your servo motor.
Regularly adding new grease will push out the old grease and any dirt that may have worked its way into the bearing housing. It is important that the old grease have a way to move out so look for a pressure relief mechanism first before adding new grease. Not checking first could result in overheating due to too much lubrication.
