As the core component in mechanical transmission, bearings carry the force and torque of rotational motion, so their operating status directly affects the performance and service life of equipment. Lubrication is one of the key factors for bearings to maintain good operation.

1、 The importance of bearing lubrication

Reduce friction and wear: Friction is inevitable during the operation of bearings, and proper lubrication can reduce the friction coefficient, decrease wear, and extend the service life of bearings.

Cooling and sealing: Lubricants can form a protective film between the bearing and the external environment, playing a role in sealing and cooling, effectively reducing the working temperature of the bearing and improving work efficiency.

Reduce noise: Good lubrication can reduce the noise generated during bearing operation, improving the smoothness and comfort of equipment operation.

2、 Bearing lubrication method

Lubricating grease: Lubricating grease is one of the most common lubrication methods, consisting of base oil and additives, with good viscosity and adhesion, suitable for high-speed, high-temperature, and sealed bearings.

Lubricating oil: Lubricating oil is suitable for high-speed bearings and continuously running machines. It has good fluidity and cooling performance, and can form a uniform oil film in the bearing to reduce friction.

Solid lubricants: Solid lubricants are usually applied to bearings that operate at high temperatures, high loads, and low speeds. Solid particles such as molybdenum, copper, lead, etc. can form a uniform lubricating film on the surface of the bearing, reducing friction and wear.

3、 Selection of Lubricants

Working conditions: Select the appropriate lubricant based on the working conditions of the bearing, taking into account factors such as bearing load, speed, temperature, etc.

Wear resistance: The wear resistance of lubricants is one of the important indicators to measure their performance. Choosing lubricants with good wear resistance can effectively extend the service life of bearings.

Temperature stability: Lubricants should not decompose or fail at high temperatures and should have good temperature stability to ensure normal lubrication of bearings under various working conditions.

Sealing performance: For sealed bearings, the sealing performance of lubricants is crucial, and lubricants with good sealing performance should be selected to prevent external pollutants from entering the interior of the bearing.

4、 Bearing lubrication and maintenance

Regularly replace lubricants: According to the usage of the equipment and the manufacturer's recommendations, regularly replace lubricants to maintain good lubrication of the bearings.

Cleaning the bearing surface: When replacing the lubricant, the bearing surface and lubrication chamber should be cleaned to prevent contaminants from entering the lubricant and affecting the lubrication effect.

Pay attention to the amount of lubricant added: too much or too little lubricant can affect the normal operation of bearings, and the amount of lubricant added should be adjusted appropriately according to the actual situation.

Pay attention to bearing temperature: Regularly check the working temperature of the bearing. If the temperature is abnormally high, the lubrication of the bearing should be checked in a timely manner to ensure its normal operation.

Bearing lubrication is one of the important factors to ensure the normal operation of mechanical equipment. Choosing appropriate lubrication methods and lubricants is of great significance for improving equipment performance and extending service life. Therefore, in practical applications, we should attach great importance to bearing lubrication technology, regularly maintain lubrication, and ensure that the bearings are in good lubrication condition to ensure the safe and stable operation of the equipment.
