What type of oil seals are needed for agricultural machinery?
Agricultural machinery often faces dust, dirt and grease mixed pollution in the field operation environment. Suitable oil seals can prevent lubricating oil leakage and external impurities from invading, ensuring the reliable operation of the equipment. The role of agricultural machinery oil seals Oil seals are mainly used in bearings, gearboxes, hydraulic systems and other parts to prevent lubricating oil or hydraulic oil from leaking out. At the same time, it can block dust, sand and other impurities from entering the equipment and reduce wear. Common materials and characteristics Nitrile rubber (NBR) NBR has good oil resistance and is suitable for occasions in contact with mineral oil at room temperature, and the cost is relatively low. Polyurethane (PU) PU has excellent wear resistance and elasticity, can withstand high pressure and frequent movement, and is often used in hydraulic systems. Fluororubber (FKM) FKM is resistant to high temperature and chemical corrosion, and is s...
