What are the solid working conditions of the pulley in the shower room?
When oil lubrication and grease lubrication can not reach or meet some specific working conditions, such as ceramic shower room calciner bearings with operating temperature over 270 ℃, satellite devices with vacuum degree higher than 10-9 Torr (anti evaporation and environmental pollution), devices in nuclear radiation (lubricating oil and other easy to deteriorate), and food, textile, medical and other machinery that are not allowed to be polluted, solid lubricants can be used.
The use of solid lubricants can avoid pollution and leakage caused by oil or grease lubrication. Solid lubricants can also simplify oil supply or grease supply facilities and reduce manufacturing costs and maintenance costs. However, the solid lubricant powder itself has some disadvantages, such as high friction coefficient, no cooling effect and short service life.
Solid lubricant is to use solid lubricant powder, coating or anti-wear materials with low friction coefficient to replace lubricating oil and grease, and isolate the surfaces of parts in contact with each other to achieve the purpose of reducing wear. Solid lubricants commonly used for rolling bearings include lead, silver, graphite, shower room molybdenum disulfide, lead oxide, polytetrafluoroethylene, nylon, etc
