Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in safeguarding your machinery. These essential components are expertly designed to secure grease, liquids, and dirt, facilitating seamless operations of any rotating or moving assembly. By maintaining the delicate balance between stationary and moving parts, oil seals ensure your mechanical equipment functions flawlessly. Typically, an oil seal is composed of three fundamental elements that form its robust structure:
Key elements include: a resilient sealing material (rubber component), sturdy metal casings, and durable springs, making it a versatile sealing solution for various applications.
Our offerings include an extensive variety of types such as: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, allowing you to find the perfect match for your requirements.
We present a broad array of premium rubber materials tailored for oil seal production, ensuring compatibility with diverse operating environments. These high-performance materials are engineered to withstand a spectrum of chemicals and endure extreme temperature fluctuations, guaranteeing reliability in any circumstance.
[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.

We offer the flexibility to create custom non-standard oil seals using superior materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, meeting your specific needs.

[Oil seal core structure type]

Single lip structure	Single channel sealing lip for low pressure reciprocating motion (e. g. automotive crankshaft oil seal)
Double lip structure	Two upper and lower sealing lips, a main seal (contact shaft), a secondary seal (dust), often used in high pressure environment
Composite lip structure	Main lip + dust lip + buffer spring (like type NOK TCV), can withstand both radial and axial forces
labyrinth packing	Multi-channel ring groove design to block oil by throttling effect (suitable for high-speed rotating axis)
Seal the oil swing ring	Metal ring rotating centrifugal oil swing with shaft (commonly used in gearbox gearbox)

[Key structural components of the oil seal]

Component name	Material selection	function declaration
seal(ing)lip	NBR/FKM/PTFE	Main seal surface, the contact shaft forms a dynamic seal
spring	Stainless steel / carbon steel	Provide lip pretension to compensate for wear
skeleton	PA6/PC	Fixed the sealing lip shape and transfer the mounting stress
Dust-proof lips	polyurethane elastomer	Blocking the entry of solid impurities (optional)
Self-lubricating coating	plumbago/PTFE	Reduce the friction coefficient and extend the life life

[Oil seal and sealing principle]
The oil seal masterfully achieves dynamic sealing by forming an oil film through the precise contact between its lip and the shaft. Utilizing the synergy of spring pressure and material elasticity, it maintains an unparalleled seal. Upon rotation, frictional heat causes the lip to contract, enhancing the seal, while stationary, it retains contact to secure the seal, ensuring optimal protection.

[Oil seal application fields]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and countless other equipment. They excel in challenging environments characterized by high temperatures, speeds, and corrosive media. In scenarios where traditional rubber oil seals fall short, our PTFE oil seals outshine, offering up to 20 times the longevity while adeptly sealing water, acid, gas, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. Ensure vertical installation to avoid tilting and apply grease to the lip, minimizing dry friction and prolonging seal life.
