Bearing alloy corrosion is generally area for the lubricating oil is not pure, lubricating oil in the chemical impurities (
Acidic oxides, etc. )
Make bearing alloy oxidation and acid generated, cause bearing alloy parts fall off, forms the rule of no small hiatal or small pits.
Bearing alloy corrosion is the main reason of the improper selection, bearing lubricating oil material corrosion resistance is poor, or the engine work violent, the temperature too high.
All bearings in the anti friction bearing basically contains two hardened steel rings, multiple hardening of ball or roller, roller or roller and a separation or maintaining aircraft separation.
These types are in use is divided into many types.
Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement.
In practice, it is necessary to use there is more than the recommended amount of grease.
When the required torque low, only very few can finish of KOYO bearing grease lubrication.
When the speed is very low and bearing exposure in dust or moisture, bearing might almost be filled.
Bearing under the condition of high speed and high temperature usually need more frequent than in general lubrication.
