Rust prevention and maintenance of rolling bearing

1, immersion method: soak rolling bearings used in antirust oil, so its surface to attach a layer of anti-rust oil. Oil-film thickness can be controlled through the rust to reach temperature or viscosity of the grease.
2, brushing method: not apply for immersion or spraying of rolling bearings or bearings with special shapes, brush both pay attention do not produce accumulation of rust preventive oil, should also pay attention to preventing the spill coated.
3, spray method: immersion method used in some large rolling bearings cannot be oiled, generally use about 0.7Mpa pressure of filtered compressed air in air cleaning spray. Spray application of solvent-diluting antirust oil or a thin layer of rust preventive oil, but you must use a full range of fire prevention and protection measures.
Cleanliness of the bearing is a great impact on the life of rolling bearings, we have held a special test for this, and as a result they differ for several times and even dozens of times to more than double. Bearing cleaning more, longer service life tests show that different lubricant cleanliness on the ball bearing life considerably. Therefore, improving the cleanliness of the lubricant can extend the life of the rolling bearing, in addition, lubricants containing dirt particles control 10um, into several fold increase bearing life.
1, impact on the vibration of our test center test results show that cleanliness seriously affect bearing vibration level, especially high-frequency vibrations more visibly. Low vibration speed and cleanliness of high value, especially in the high frequency band.
2, noise impacts on dust impacts on noise of rolling bearing greases do tests to prove that dust as much noise as possible.
3, effects on the lubrication properties of rolling bearing cleanliness declined, not only affect the lubricant film formation, also can cause deterioration of the grease and to accelerate their aging, thus affecting the grease lubrication performance.
