In the bearings or trunnion, artificially join solid lubricant, to minimize friction, the bearing called solid lubricating bearings.
Solid lubrication bearings and no lubrication bearing in the nature of the friction there is no difference between a, just solid lubrication in the surface layer of friction bearings of solid materials is to prevent to two agglutination, reduce the surface friction coefficient, decreasing wear whatever the placement.
Use solid lubricant to save electricity, petroleum products and non-ferrous metal, avoid oil pollution environment. Solid lubrication applicable occasions for:
1. The high temperature and high pressure working environment, such as extrusion, pressing, control, suppress, etc.
2. Low speed conditions, such as machine slideway.
3. The wide range of temperature.
4. High vacuum conditions operation of the parts, lubrication is destroy the vacuum.
5. Strong radiation conditions operation of the parts, solid lubricant in strong under the irradiation of metamorphic slowly.
6. Need anti-corrosion occasions, solid lubricant and air, solvents, fuel, accelerant afford to wait, reaction, can be in acid, alkali, sea water and the environment.
7. Have dust environment.
8. Must strictly avoid oil contamination of the product of occasions, such as food, textile, papermaking, medicine, printing and so on the equipment.
9. Oil is washed the loss of the occasion.
10. Oil supply is not convenient occasion.
Solid lubrication friction factor than oil, grease lubrication usually when high, and have no the cooling effect, does not help honing eduction.
