Best Grease For Electric Motors

Category: grease 👁 287 👍 11 ★★★★☆4.6

Expert advice: When oiling an electric motor, be sure to use oil that's specifically designed for motors. When oiling an electric motor be sure to use special oil for lubricating electric motors. Other oils could cause excess wear and premature failure.

Add on, how often should you grease electric motor bearings?

When the operating temperature is between 80°C - 100°C (176°F - 212°F), oil should be replaced at least every three months. For critical equipment, it is advisable that lubricating oil be analyzed at least every three months to determine when oil replacement is necessary.

Really, can you grease an electric motor while running? Care must be taken to follow the simple rule of 1-2 seconds between grease gun strokes and to grease while the motor is running. NEVER use an electric grease gun to grease an electric motor. A disadvantage of shielded bearings is an increase in friction and temperature of the bearing.

Electric Motor Bearing Lubrication Procedure

  • Ensure the grease gun contains the appropriate lubricant.
  • Clean the areas around the relief and fill fittings.
  • Remove the grease relief valve or drain plug.
  • Grease the bearing with a calculated amount of grease. ...
  • Watch for grease coming out the relief port.
  • Can I use wd40 on an electric motor?

    Yes, WD-40 is safe to use on electronics. It is used frequently to dry out auto ignition systems as it it non-conductive, displaces water, and lubricates the parts without getting sticky. I also use it to clean up and dry out computers and power supplies.

    15 More Questions Answered

    How often should you grease electric motors?

    Inspect, clean, and test motors at regular intervals— approximately every 500 operating hours or every three months, whichever comes first. Lubricate motors at the intervals determined herein. Keep accurate maintenance records.

    How much grease should you put in a bearing?

    Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.

    What happens when you over grease a bearing?

    Too much grease builds pressure, pushing the rolling elements through the fluid film and against the outer race. The bearing now has to work much harder to push the rolling elements through a mud bog of grease. The increased friction and pressure from too much grease raises the temperature inside the bearing.

    How do you lubricate a bearing?

    The air/oil method of lubrication, also known as the oil-spot method, uses a similar air and oil combination to provide lubrication to bearings. This method uses compressed air to move a precise amount of lubricant directly into the bearing, but unlike the oil mist method, there is no atomization of the air or oil.

    How do you stop a greasing bearing?

    Three Ways to Prevent Over Lubrication of Bearings Calculate the exact amount that the bearing needs using the bearing speed, width, outer diameter and a factor for quantity. Then lubricate with careful self-discipline. 2. Install a grease vent plug on a relief port in the bearing.
