You must have some understanding of chain guide rail, even though it is not in the mechanical machine tool industry, you will not be unfamiliar with it. It exists in every corner of your life, such as cars, subways, doors and windows, and of course, including all machines in the machinery and industry.
Although the chain guide rail has high accuracy, it may be damaged due to friction after use for a period of time, so it requires necessary lubrication and maintenance. A common problem in lubrication and maintenance is that the newly replaced lubricating oil quickly turns black, which many people cannot understand.
The blackening of lubricating oil is related to the fuel used. The higher the olefin content in the fuel, the higher the sulfur content, and the easier it is to form oil sludge. When changing the lubricating oil, the engine interior and oil pan are not cleaned. The oil sludge from the lubricating oil used in the past is deposited in the oil pan and inside the engine. After adding new lubricating oil, due to the effect of the cleaning dispersant in the new lubricating oil, some oil sludge, carbon deposits, and gum inside the engine are dispersed in the new lubricating oil, making it black.
Secondly, the website optimization company found that the engine's high temperature caused the oxidation of lubricating oil into a colloidal form, which was suspended in the lubricating oil and turned black due to the effect of the detergent dispersant in the new lubricating oil.
Finally, the blackening of the lubricating oil is also related to the quality and replacement cycle of the lubricating oil filter element and air filter element. If the air filter element is of poor quality or not replaced in a timely manner, dust and impurities will enter the cylinder and adhere to the cylinder wall before mixing with the lubricating oil to pollute the lubricating oil.
In summary, blackening of lubricating oil is not necessarily due to poor lubricating oil quality. Due to the presence of a detergent dispersant in good lubricating oil, it can clean and disperse the previously existing gum, paint film, carbon deposits, etc. inside the engine, making it suspended in new oil, making the oil more likely to turn black; Poor quality or inferior lubricating oils may also experience blackening shortly after use. Due to the poor antioxidant and high-temperature resistance of inferior lubricating oils, they are prone to deterioration. So when choosing lubricants, it is necessary to carefully choose products with reliable quality or well-known brands of lubricants, which not only provides certain guarantees but also ensures safe use.

Chain guides are mostly made of hardened steel and placed on the equipment surface after precise grinding. In order to be used in environments that require corrosion resistance, some linear activity systems can use martensitic stainless steel. Then, the surface of the fine linear chain guide rail: the chain guide rail system, the surface of the chain guide rail and shaft can be treated for rust or aesthetic purposes.
