Product Description Oil seals, often known as rotary shaft seals, are indispensable guardians of mechanical vitality. They masterfully shield grease, liquids, or grime from infiltrating sensitive equipment areas. As a vital component in any rotating and moving assembly, these seals harmonize the interaction between stationary and dynamic parts of machinery. An oil seal traditionally comprises three pivotal elements:A robust sealing material (rubber component), resilient metal casings, and tension springs. Together, they form a multifaceted sealing apparatus.Our repertoire includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, to name a few.We proudly offer an extensive array of rubber materials tailored for oil seal fabrication, ensuring applicability across varied operational landscapes. These superior rubber compounds are adept at withstanding a plethora of chemicals and temperature extremes, both searing and freezing.[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.Our customizable non-standard oil seals can be crafted from advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet your specific requirements.[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 ingeniously forms an oil film via the lip-to-shaft contact, achieving dynamic sealing through the synergy of spring tension and elastic material properties. During rotation, frictional heat causes the lip to contract, augmenting its sealing prowess; while at rest, sustained contact ensures ongoing integrity.[Oil seal application fields]Our oil seals find extensive applications in engines, gearboxes, hydraulic pumps, reducers, and more, especially under high temperature, acceleration, corrosive media, or where traditional seals falter. For example, PTFE oil seals endure up to 20 times longer than standard varieties, expertly sealing water, acids, gases, and other challenging media.[Oil seal selection and installation]Consider the shaft's rotation speed, ambient temperature, pressure, and medium characteristics meticulously. Ensure vertical shaft installation to prevent misalignment and lubricate the lip with grease to minimize dry friction.product superiority:We diligently select prime materials, crafting parts that exemplify unparalleled performance, stability, and integration of cutting-edge automation.Our offerings shine with exceptional elasticity and wear resistance, maintaining unparalleled stability even in the harshest conditions.Backed by a comprehensive team of technical experts, we offer bespoke customization, delivering timely and precise solutions to meet unique customer needs.Adhering strictly to our robust quality control framework, we proudly serve as a direct or indirect supplier to numerous elite global enterprises.
