Complete Guide on How to Lubricate Motor Bearings [Quick]

Reliable lubrication of the motor bearings is necessary to maintain optimum operating conditions and ultimately reduce unnecessary downtime.

Grease lubrication Features

People often use grease for a motor bearing lubricant because of its convenient application and unique properties. The main functions of motor bearing grease are:

  • reduce friction and prevent wear
  • Prevent bearing corrosion
  • It acts as a seal to prevent the entry of contaminants

The Function of Bearing Grease Lubrication

Grease is a semi-solid lubricant consisting of base oil, a thickener and an additive. In addition, these components combine together under complex chemical reactions at a controlled temperature and pressure. Therefore, the base oil used in the grease may be mineral oil or synthetic oil.

So mineral oils are available for most motor bearing applications. However, synthetic base oils are usually for extreme temperature applications or for applications that require longer relubrication.

People use the thickener primarily as a carrier for the base oil and prevents the base oil from leaking in the application. Some commonly used thickeners include metal soaps composed of calcium, lithium, sodium, aluminum or bismuth and composite metal soaps such as lithium complex soaps. A thickening agent has wide application in motor bearing lubrication is polyurea.

As with many types of lubricants, people often use additives to improve grease performance. Commonly used additives include preservatives, antiwear and extreme pressure agents, antioxidants and etchants, pour point depressants, lubricants, dyes or pigments.

Motor Bearings Lubrication application

  • Conducive to the operation of high-speed motor rolling bearings and equipment at high temperatures.
  • Long-term lubrication and anti-corrosion for high-temperature bearings and heavy load bearings. Such as vulcanizer bearings in the chemical industry, induced fan bearings in the power industry, and high-temperature bearings in the paper industry. Therefore, it is suitable for motor bearings that require a continuous, long-term reliable operation.
  • Used for textile machinery bearings, marine work bearings, high-temperature sintering furnace bearings, kiln car bearings, baking and hot air bearings, water pump bearings, chip mounter cams, Raymond machine bearings, rollers that require water resistance and corrosion resistance Lubrication, rust and corrosion resistance of press bearings.
