Lubricants for chain drives should have viscosity at different operating temperatures
If the use temperature is higher (such as furnace box chain) or the use environment is very bad, mud splashing and other open or heavy load vulgar chain transmission, disulfide M0S2, WS2. Or selenide MoSE2.WSE2 can improve lubricity either as additive or direct spray.
Greases with low viscosity or a dropping point around 70° are also suitable for manual lubrication. In some special occasions, use liquefied grease for spray lubrication. The unstable substances can start to work after volatilization
Regardless of the lubricant and lubrication method used. The most important problem is that the lubricant can be fully and evenly distributed in time to the gaps at the chain link hinges that constitute the friction pair (between the pin shaft and the sleeve. Between the sleeve rollers)
Ambient temperature Lubricant viscosity
-5℃~+25℃ N100（ISO VG 100）
+25℃~+45℃ N150（ISO VG 150）
+45℃~+60℃ N220（ISO VG 220）
