Effect of lubricating oil on the performance and life of INA universal joint bearings

INA bearing lubricants can be broadly divided into two categories: lithium-based and calcium-based. Vibration control systems can help solve problems. Based on the application technology of the LM Guide Ball Screw, the system protects people's lives and lives during an earthquake. The system not only prevents damage caused by earthquakes, but also has excellent water resistance, mechanical stability and chemical stability of lithium-based lubricating oil. Lithium soap has strong thickening ability, and extreme pressure is added to the grease. After adding additives such as agents and rust, a variety of long-life fats are prepared. It can also reduce people's panic because of their ubiquity, reliability and durability. Brick machine bearings use harsh environment, long time, heavy load and difficult maintenance. Therefore, most of them use lithium-based lubricants.

If there are foreign objects such as iron filings, burrs, dust, etc. in the INA bearing, it will cause noise and vibration during the operation of the universal joint bearing, and even damage the raceway and rolling elements. Therefore, before installing the bearing, you must ensure that the mounting surface and the installation environment are clean.

Lubrication has a very important influence on the operation and life of INA bearings. Grease is made from base oils, thickeners and additives. The performance of the grease is primarily determined by the base oil. Generally low viscosity base oil is suitable for low temperature and high speed; high viscosity is suitable for high temperature and high load.

The thickener is also related to the lubricating properties, and the water resistance of the thickener determines the water resistance of the grease. In principle, the different greases of the brand cannot be mixed, and even the grease of the same thickener may have a bad influence on each other due to the different additives. The universal joint bearing surface is coated with anti-rust oil, which must be carefully cleaned with clean gasoline or kerosene, and then cleaned with high-quality or high-speed high-temperature grease for installation. Fully enclosed bearings do not need to be cleaned and refueled.

After the INA bearing is installed, if it is not carefully aligned, alignment may result in additional loads, friction and vibration of the bearing. These can accelerate fatigue and reduce bearing life and can damage the life of other machine parts. In addition, increased vibration and friction can greatly increase energy consumption and risk of premature failure.
