Product Description

Oil seals, or rotary shaft seals, play a pivotal role in ensuring the seamless operation of any rotating or moving assembly. These essential components expertly seal in grease, liquids, or dirt, while flawlessly stabilizing the space between stationary and dynamic parts within mechanical equipment. An oil seal comprises three indispensable elements:
This meticulously engineered assembly consists of a sealing material (rubber component), robust metal casings, and dependable springs, delivering a versatile and comprehensive sealing solution.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed to meet varying and diverse sealing requirements.
Discover our broad selection of premium rubber materials, intricately designed for crafting high-performance oil seals. These materials are meticulously engineered to resist a wide array of chemicals and endure extreme temperature fluctuations, both high and low.
[Introducing Oil Seal Materials]

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 excel in the art of crafting customized non-standard oil seals using top-tier materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring unmatched quality.

[Oil Seal Core Structure Types]

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)

[Essential 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 Its Sealing Principle]
The oil seal ingeniously forms an oil film through precise contact between its lip and the shaft. This dynamic sealing action utilizes spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing seal effectiveness; while stationary, it maintains contact to preserve the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals find extensive applications in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, surpassing traditional rubber oil seals. PTFE seals, for instance, boast a lifespan up to 20 times longer, efficiently sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
Take into account the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical installation to prevent tilting and apply grease to the lip to minimize dry grinding.
