Common faults for sliding bearings are as follows:
1, tile surface corrosion: spectral analysis found that non-ferrous
metal element concentration anomalies; iron spectrum in the emergence of
many non-ferrous metal components of sub-micron wear particles;
lubricants moisture exceeded, acid value exceeded.
2, imported bearing journal surface strain: iron in the iron cutting
grain or black oxide particles, the presence of metal surface tempering
color.
3, bearing journal surface corrosion: spectral analysis found that
iron element concentration anomalies, iron spectrum has many iron
components of submicron particles, lubricating oil moisture or acid
value exceeded.
4, bearing surface strain: iron found in the cutting abrasive, abrasive composition of non-ferrous metals.
5, tile back fretting wear: spectral analysis found that iron
concentration anomalies, iron spectrum in many iron components submicron
wear particles, lubricating oil moisture and acid value anomalies.
A bearing that operates under sliding friction. Oil-free sliding bearings work smoothly, reliable, no noise. In
the liquid lubrication conditions, the sliding bearing sliding surface
is separated by lubricating oil without direct contact, but also can
greatly reduce the friction loss and surface wear, oil film also has a
certain vibration absorption capacity.
