Used on the INA bearing grease must have rust, rust can best do not dissolve in water. Oil should have a good report of them can form a thin oil film on the steel surface, even if grease is filled with water and can be maintained. Grease the machine will be softer, resulting in leaks.
Application example of when there is vibration, oil will be left to INA bearings, INA bearing block. If the mechanical stability of the grease is not, INA bearing oil will continue to be thrown out, which causes the mechanical understanding and collapse the structure of SOAP used oils were damaged.
1, through the surface feels INA bearing quality
INA bearing bright should be the kind of glossy black surfaces, this glossy black is INA bearing caused by the use of steel is standard and the grinding and cutting fluids are used, previously two of them.
2, chamfer is bright
INA bearing a chamfer does not determine the quality of INA bearing, but it reflects the INA bearing processing method. Chamfering is black to explain heat treatment such as quenching, so increasing the hardness of INA bearing, and some people think that the chamfers are black does not look good is not processed completely, this is a misunderstanding.
3, good one cage two-body, while the new technology uses one cage, but it just saves material, on rotation, and other properties than the difference of the two.
In General, the INA bearing service life and relationship factors 3, a INA bearing their quality. Second is to use the environment. Third, installation method.
There is the color way dimming of samples or thick, so may indicate that the oil has begun to carbide should be completely replaced the old lubricant. If possible, use fresh lubricant to rinse the circuit. When replacing the oil, the lubricant should be replaced to ensure that the new and old of the same model, adding that to meet the requirements of the oil level.
