Self-lubricating bearings some failures often appear

Some failures often appear self-lubricating bearings. Bearing common faults are as follows:
1, tile surface corrosion: spectral analysis found abnormal concentrations of non-ferrous metal elements; iron spectrum, there have been a number of sub-micron wear particles of non-ferrous metals; lubricants excessive moisture, acid value exceeded.
2, imported bearing journal surface strain: iron spectrum in the presence of an iron-based cutting abrasive temper color or black oxide particles, the metal surface.
3, the bearing surface corrosion journal: spectral analysis found abnormal concentrations of iron, iron spectrum, there are a number of sub-micron particles of iron components, lubricants excessive moisture or acid value exceeded.
4, the bearing surface strain: iron spectrum found in cutting abrasive, abrasive component of non-ferrous metals.
5, tile back fretting: spectral analysis found abnormal concentrations of iron, iron spectrum, there are many iron content submicron wear particles, water and lubricating oil acid value exception.
Sliding movable bearings operating under sliding friction. Oil-bearing smooth, reliable, no noise. In the liquid lubrication conditions, the sliding surfaces are separated from lubricating oil without direct contact, but also can greatly reduce the friction losses and wear surface, the film also has a certain vibration absorption ability. The use of oil-free sliding bearings, use is very extensive, we experience a failure for plain bearings appearing us how to solve it? What better way to do it? I hope a lot of attention to our website.
