Requirements of Lubricating Grease for Automobile Sliding Bearings
Introduction
Nowadays, the development of industry has changed people’s lifestyles and ways of production. Cars can be seen everywhere and are used for a variety of purposes, from transportation to leisure. Modern cars are often equipped with sliding bearings in order to improve ride comfort, reduce friction and improve overall performance. Sliding bearings are able to move freely in a limited space, allowing cars to absorb more shock and vibrations on the road.
However, sliding bearings require lubrication with lubricating grease to reduce friction, reduce energy losses and extend the service life of the bearings. Lubricating grease is an important part of the bearing, and it must meet certain requirements in order to work properly and ensure long-term operation of the bearing.
Requirements for Automotive Sliding Bearings
1. Ability to resist high temperature and pressure. Automotivesliding bearings are often exposed to extreme temperatures, from the heat of the sun to the cold of winter, as well as high pressures from the use of the vehicle. The lubricating grease must be able to withstand temperature and pressure changes without breaking down and compromising the lubricating effect.
2. Good adhesion and cohesion. Lubricating grease must be able to adhere to the sliding bearings and not leak away or become diluted. It must also be able to remain cohesive during use so that it maintains its lubrication properties.
3. High viscosity. Viscosity is the measure of a fluid’s resistance to flow. High viscosity means that the lubricating grease is thick and resists flow, allowing it to remain in place while in use.
4. Low friction coefficient. The friction coefficient is a measure of the force of friction between two surfaces. Low friction coefficient means that the lubricating grease is able to reduce the force of friction between two surfaces, allowing the bearing to move more freely and reducing wear and tear.
5. Water resistance. Automotivesliding bearings are exposed to a variety of extreme environments, from dust and dirt to water and road salt. The lubricating grease must be able to resist water so that it does not wash away or become diluted.
Conclusion
Sliding bearings are widely used in automobiles due to their ability to reduce friction and improve overall performance. To ensure optimal performance and longevity of the bearing, it is important to use lubricating grease that meets certain requirements, such as the ability to resist high temperature and pressure, good adhesion and cohesion, high viscosity,low friction coefficientand water resistance.
