Product Description Product DescriptionOil seals, also known as rotary shaft seals, are the unsung heroes of machinery, expertly sealing grease, liquids, or dirt to ensure smooth operation. These vital components stabilize the space between stationary and moving parts in mechanical equipment, offering reliability and efficiency. Typically, an oil seal consists of three fundamental elements:The sealing assembly is a marvel of engineering, comprising a sealing material (rubber component), metal casings, and springs. This versatile design is the hallmark of durability and reliability.Explore our extensive range of types including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.Our selection of high-performance rubber materials for oil seals is second to none, engineered to withstand a myriad of chemicals and extreme temperatures. They are meticulously crafted to perform under various operating conditions, whether facing the intensity of high heat or the chill of low temperatures.Product Parameters[Oil seal material introduction]Ding Rubber (NBR)Temperature resistance of 100oC, good oil resistance, wear resistance, anti-aging, good sealing effect.silica gel (VMQ)Temperature resistance of 200oC, general oil resistance, high temperature resistance, good waterproof, non-toxic.Fluorogel (FKM)Temperature resistance of 280oC, good oil resistance, wear resistance, high pressure resistance, corrosion resistance.ethylene-propylene-diene misch-polymere (EPDM)Temperature resistance of 150oC, general oil resistance, corrosion resistance.(PTFE)Temperature resistance of 280oC, good oil resistance, wear resistance, high pressure and corrosion resistance.polyurethane (PU)Temperature resistance of 90oC, good oil resistance, wear resistance.For those unique needs, we offer customizable non-standard oil seals crafted from specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring bespoke solutions for your specific challenges.[Oil seal core structure type]Single lip structureSingle channel sealing lip for low pressure reciprocating motion (e. g. automotive crankshaft oil seal)Double lip structureTwo upper and lower sealing lips, a main seal (contact shaft), a secondary seal (dust), often used in high pressure environmentComposite lip structureMain lip + dust lip + buffer spring (like type NOK TCV), can withstand both radial and axial forceslabyrinth packing Multi-channel ring groove design to block oil by throttling effect (suitable for high-speed rotating axis)Seal the oil swing ringMetal ring rotating centrifugal oil swing with shaft (commonly used in gearbox gearbox)[Key structural components of the oil seal]Component nameMaterial selectionfunction declaration seal(ing)lipNBR/FKM/PTFEMain seal surface, the contact shaft forms a dynamic sealspringStainless steel / carbon steelProvide lip pretension to compensate for wearskeletonPA6/PCFixed the sealing lip shape and transfer the mounting stressDust-proof lipspolyurethane elastomerBlocking the entry of solid impurities (optional)Self-lubricating coatingplumbago/PTFEReduce the friction coefficient and extend the life life[Oil seal and sealing principle]The oil seal operates on a sophisticated principle, creating an oil film through the dynamic interaction between the lip and the shaft. Utilizing spring pressure and the inherent elasticity of the materials, it ensures a robust seal. During operation, frictional heat causes the lip to contract, enhancing the seal, while in rest mode, it maintains its grip to ensure integrity.[Oil seal application fields]Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, where traditional seals might fail. Take, for example, our PTFE oil seals, which offer longevity up to 20 times that of conventional seals, effectively sealing water, acids, gases, and beyond.[Oil seal selection and installation]When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical installation to prevent tilting, and apply grease to the lip to mitigate dry grinding, thereby extending the longevity and efficiency of the seal.Product Superiority:We dedicate ourselves to selecting premium materials and crafting parts that embody exceptional performance and stability, equipped with cutting-edge automation to meet the highest standards.Our products shine with superior elasticity and wear resistance, ensuring peak performance even in the most demanding environments.Our team of technical experts stands ready to customize products to your needs, offering timely solutions and unparalleled support.Adhering strictly to our meticulous quality control system, we have earned our place as a valued supplier to globally renowned enterprises, delivering excellence consistently.Detailed PhotosCompany Profile Packaging & Shipping FAQ
