Product Description

Oil seals, also known as rotary shaft seals, are pivotal components in any rotating or moving assembly. They expertly manage to seal grease, contain liquids, or fend off dirt, meticulously stabilizing the space between stationary and moving parts of mechanical equipment. An oil seal is ingeniously crafted from three critical elements:
This assembly artfully includes a high-quality sealing material (rubber component), robust metal casings, and dependable springs, providing a versatile and effective sealing solution.
Our product offerings include an extensive range of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, which are designed to cater to a multitude of sealing needs.
Discover our comprehensive selection of premium-grade rubber materials, specifically tailored for crafting high-performance oil seals. These materials are engineered to resist a broad spectrum of chemicals and to endure extreme temperature variations, 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 developing customizable non-standard oil seals using top-notch materials such as fluorine rubber, silicone rubber, high-grade rubber, and propylene rubber, ensuring unmatched quality and performance.

[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 innovatively forms an oil film through the precise contact of its lip with the shaft. This dynamic sealing mechanism leverages the pressure of a spring and the inherent elasticity of the material. During motion, frictional heat contracts the lip for an enhanced seal; while at rest, it retains contact, preserving the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals are widely employed in engines, gearboxes, hydraulic pumps, reducers, and other equipment. They thrive in high-temperature, high-speed, and corrosive environments, vastly outperforming traditional rubber oil seals. For example, PTFE seals deliver up to 20 times the lifespan, adeptly 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 a vertically aligned shaft installation to prevent tilting, and apply grease to the lip to reduce the risk of dry grinding.
