Type:oil seal
Commonly used materials for oil seals are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc.
1. Nitrile rubber (NBR)
It has good heat resistance and wear resistance, and is resistant to various lubricating oils, greases, and oil-air mixtures. The applicable temperature is -30~120 degrees Celsius, but it cannot be phosphate ester hydraulic oil and gear oil containing extreme pressure additives. Stable performance in mineral oil with aniline point.
2. Polyacrylate rubber (ACM)
Excellent oil resistance, heat resistance, wear resistance, ozone resistance, ultraviolet radiation resistance, especially extreme pressure liquids, including lubricating oil, gear oil, engine oil, engine oil, petroleum hydraulic oil, suitable for -30~150 degrees Celsius work within the range.
3. Fluorine rubber
Aging resistance, heat resistance, oil resistance, suitable for almost all lubricating oils, fuel oils, gasoline, not easy to harden in oils containing extreme pressure additives, but poor cold resistance, high temperature wear resistance, large permanent compression deformation, applicable temperature -20~250 Celsius.
4. Silicone rubber
It has outstanding high and low temperature resistance performance, and can be used for a long time at 150 degrees Celsius; it can be used continuously for 10,000 hours at 200 degrees Celsius, and can maintain its unique flexibility and ozone resistance in the working temperature range of -70~260 degrees Celsius. advantages such as weather resistance.
5. Teflon
It has outstanding chemical stability, thermal stability, anti-friction and self-lubricating properties, and its cracking temperature is above 400°C, so it can work in the temperature range of -200 to 300°C. It has excellent corrosion resistance to chemicals, solvents, hydroxides and acids, except for free fluorine and alkali metals. Compared with fluorine rubber, nitrile rubber has a wide range of oil seals and low cost, but the heat resistance and sealing performance are significantly improved, but the cost is high, and there are still some common rubber
Unfavorable commonality of materials, such as poor wear resistance, short service life, particularly sensitive to eccentric shaft response, oil leakage and other phenomena are common. PTFE oil seal is a product with high technical content, which is the development direction of oil seal in the future
