We've done several important articles about bearing lubrication (see them here and here). It is an important issue, because faulty bearings are the cause of the majority the electric motor failures that come into our shop for repair. Lubricants are critical because they: Reduce wear Prevent corrosion Reduce heat Prevent contaminants To keep electric motors running [...]
If rolling bearings are to operate reliably and realize their full service life, the must be adequately lubricated. The function of the lubricant is to form a protective oil file that separates the bearing components and prevent metal to metal contact. The lubricant also protects the bearing and related components against corrosion. When grease is [...]
Bearing life is often determined by the number of hours it will take for the metal to fatigue. To better understand metal fatigue, try the following experiment. Grab a paperclip, pinch then end piece and slightly flex or pull and then release. Notice how it returns to the same position? You could repeat this process [...]
