Oil-free self-lubricating bearings need to pay attention when using the errors

Blindly selecting lubricants: Lubricating oils act to lubricate, cool, clean, and seal. The quality of lubricants is directly related to the length of life of the engine. The engine oil is black when the engine oil is black. The engine oil is operated under harsh high temperature conditions and is easily oxidized and degraded, generating acidic substances and superimposing synthetic polymer deposits, resulting in destructive lubrication. Diesel vehicles use petrol engine oil: The engine oil is divided into gasoline engine oil and diesel engine oil. Although the gasoline engine and the diesel engine also work under high temperature, high pressure, high speed and high load conditions, there is still a big difference between the two.
