A Complete Guide to Electric Motor Regreasing

Most electric motors are equipped with anti-friction, grease-lubricated rolling-element bearings. These bearings are predisposed to fail along with your equipment if they are not lubricated properly—in fact, bearing troubles account for 50 to 65 percent of all-electric motor failures. The most common lubricant-related failures include improper lubricant selection and over-and under-greasing. With the right regreasing strategy, you can actively work to prevent these failures and prolong the life of your equipment.
