Prevent INA Mosaic solid lubricated bearing corrosion method of maintenance

Judgment standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, INA bearings shall not be used again, must be replaced. In the process of using Mosaic solid lubricated bearing, grease is critical. If bad grease, used, don't effect not only, also can damage the bearing. Be twist lubricating oil between the thumb and forefinger grinding, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel fingers between the larger friction feeling such as sand, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced. Bearing raceway groove sound sound and its control method is when Mosaic solid lubricated bearing operation, the roller rolling on the surface of the raceway and a line of continuous sound, is unique to occur in all rolling bearings of the basic sound. General INA bearing ring raceway is combined with other sounds. Ball bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but its total sound pressure level increases with speed to speed up. Raceway large bearings, the rolling sound of sound pressure level decrease with the increase of the viscosity; The raceway small bearings, the sound pressure level in the viscosity increases to about 20 was/s above, from decreased to increase somewhat. And the rigidity of the bearing, the greater the raceway of the lower the total sound pressure level. Such as radial clearance is too small, the total sound pressure level and race master frequency will increase sharply with the decrease of radial clearance. Control of raceway acoustic methods are: using low noise bearing is bearing waviness is very small, that is, carefully select and use conditions. Race often affect the mechanical noise, reduce the raceway can reduce the mechanical noise. Corrosion reasons: because the INA bearing is affected by a variety of internal and external factors, bearing corrosion phenomenon more and more, generally has the following six main reason: 1, the bearing metal material chemical composition and structure of the problem itself. 2, bearing metal surface finish by oxygen concentration cell corrosion. 3, bearings and other metal surface contact. 4, bearing metal surfaces in contact with all sorts of environmental media. 5, bearing is influenced by environmental temperature and humidity. 6, there is sweat and cause reason of corrosion of INA bearings, its pH value of 5 ~ 6. So in order to prevent hand sweat cause corrosion, installation and production personnel should wear gloves, don't contact with the hand Mosaic solid lubrication bearing. Preventive measures: to prevent bearing corrosion, can do some preventive measures. As can be tu rust-proof oil to prevent rust on them. Three methods of oil is described below. 1, use the method of soaking, make its INA bearing surface adhesion on a layer of anti-rust oil. For some small bearings can be soaked in antirust oil, oil film thickness can be controlled by the antirust oil temperature or viscosity to achieve. 2, use the method of brush: should pay attention to when brush evenly daub in Mosaic solid lubricated bearing surface, the best don't build up, also should pay attention to prevent leakage. 3, use the method of spray: for some large antirust content is not suitable for oil by soaking method, solvent spray method apply XiShiXing rust-proof oil or thin layer of anti-rust oil. But beware, this method must adopt comprehensive fire prevention and labor protection.
