The general work of FAG bearings with dilute oil and oil mist lubrication, the lubrication methods have their own characteristics, but to meet the work roll bearing in modern high speed, high load requirements of the work, it may be considered that is the most suitable oil gas lubrication.
Have an important influence on the fatigue life of FAG bearing lubrication and friction, wear, temperature, vibration, nine outstanding characteristics of ceramic bearings without proper lubrication, cannot work bearing. Analysis shows that the reason of the damaged bearing, bearing damage about 40% related to poor lubrication. Therefore, good lubrication FAG bearing is one of effective measures to reduce friction and wear. In addition, the bearing lubrication and cooling, anti-rust, sealing, ease the impact of various functions such as,
The oil - air lubrication, the service life of the actual work of the roller bearing has been greatly improved, the rolling surface of the wear and damage and grease lubrication improvement compared to me. Bearing to the lifetime of 1/3-1/4, must have a general cleaning, and measurement of FAG bearing internal clearance, when two times of bearing internal clearance greater than the original clearance, should be adjusted, after cleaning and inspection after the bearing in the installation, should replace the loading region ( the outer ring to rotate 90 degrees and then and the bearing seat. )
In high-speed, high-temperature conditions, adjustment scheme of grease lubrication FAG bearing position and clearance has not adapted to be used lubricating oil. The lubricating oil circulation, can take away a lot of heat. Viscosity is an important characteristic of lubricating oil, oil film thickness of liquidity and the friction surface viscosity is directly affected by the size of the lubricating oil, lubricating oil working temperature bearing lower viscosity is generally 12-15cst. Higher speed should be selected lower viscosity, the heavier the load should be selected high viscosity. Lubricating oil is commonly used mechanical oil, high speed machine oil, turbine oil, compressor oil, transformer oil, cylinder oil etc..
FAG bearing in operation due to wear and the bearing internal clearance. Bearing clearance increases and the causes of bearing internal load region to reduce running noise, unfavorable factors increase. Therefore, in considering the use of bearing clearance standards, should first according to whether the working condition of host allows the use of bearing clearance after.
