Seal Material from WONEPART
Seal Material from WONEPAT
We WONEPART have our company logo and website symbol as YUDI TECHNOLOGY GLOBAL CO.,LTD.
Our goal is part for all parts for you. We wonepart supply all kinds of construction machines parts, seals, seal kits, hydraulic breakers, hydraulic hammer parts for different brand, hydraulic pump parts and engine parts. Besides, we could manufacture based on customer requirement.
For seal, we have the brand NOK, Corteco, CFW, SKF, Halite, Parker and so on.
For Matieral, we have the common materials for oil seals are: nitrile rubber, fluoro rubber, silicone rubber, acrylate rubber, polyurethane, PTFE and so on.
Nitrile rubber (NBR)
It has good heat resistance, wear resistance, resistance to various lubricating oils, greases, oil and gas mixtures, etc., suitable for temperatures of -30 ~ 120 degrees Celsius, but can not be phosphate ester hydraulic oil and gear oil containing extreme pressure additives Used in the performance of gasoline and low aniline point mineral oil.
Polyacrylate rubber (ACM)
Excellent oil and heat resistance, wear resistance, ozone resistance, UV radiation resistance, especially lubricating oil, gear oil, motor oil, engine oil, petroleum hydraulic oil, etc., suitable for -30~150 degrees Celsius Scope work.
Fluororubber (FPM)
It is resistant to aging, heat and oil. It is suitable for all lubricating oils, fuel oils and gasoline. It is not easy to harden in oils containing extreme pressure additives, but it has poor cold resistance, high temperature wear resistance and long permanent compression deformation. At a temperature of -20 to 250 degrees Celsius.
Silicone Rubber
It has outstanding high and low temperature resistance and can be used for ultra long-term use at 150 degrees Celsius without performance change. It can be used continuously for 200 hours at 200 hours. It can maintain its unique elasticity and ozone resistance and resistance within the working temperature range of -70~260. Advantages such as weather.
PTFE
It has outstanding chemical stability, thermal stability, friction reducing and self-lubricating properties, and its cracking temperature is above 400. Therefore, it can work normally in the temperature range of -200 to 300 degrees Celsius. In addition to free fluorine and alkali metals, it has excellent corrosion resistance to chemicals, solvents, hydroxides and acids [2].
Nitrile rubber and fluororubber materials are widely used oil seals, the former is low in cost, but the temperature and sealing properties are significantly improved, but the cost is high, and still have some common commonalities of ordinary rubber materials, such as poor wear resistance. The service life is short, the eccentric reaction to the shaft is particularly sensitive, and the leakage phenomenon is still relatively common. PTFE oil seal is a kind of high technical content, which is the direction of oil seal development in the future [2].
When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the operating temperature range, and the ability of the lip to follow the high speed rotation of the rotating shaft must be considered. Generally, the temperature of the lip of the oil seal is higher than the temperature of the working medium by 20~50 °C, and should be paid attention when selecting the oil seal material. The working range of the oil seal is related to the material used in the oil seal: -40~120 °C for nitrile rubber (NBR), -30~180 °C for ACM, and 25~300 °C for fluororubber (FPM).
We wonepart will take part in auto-mechanic fair and Bauma Shanghai fair to promote our products and will show our newly samples to customers.
Our parts have guarantee for you if you buy from our online shop.
