Product Description

Oil seals, also known as rotary shaft seals, are crucial components in any assembly with rotating or moving parts. They expertly prevent the ingress of grease, liquids, or dirt, ensuring a stable interface between the stationary and dynamic elements of mechanical systems. Comprised of three vital components, these seals play a pivotal role in maintaining operational integrity.
The assembly is crafted with a sealing material, typically a high-grade rubber component, complemented by robust metal casings and reliable springs. Together, these elements create a versatile and effective sealing solution.
We offer a diverse range of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others. Each type is designed to meet specific sealing requirements with precision.
Discover our broad selection of premium rubber materials, meticulously designed for crafting high-performance oil seals. These materials are engineered to resist an extensive array of chemicals and withstand extreme temperature variations, from scorching highs to frigid lows.
[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 producing customizable, non-standard oil seals using top-quality materials such as fluorine rubber, silicone rubber, refined rubber, and propylene rubber.

[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 forms an oil film through the precise interaction between its lip and the shaft. This dynamic process harnesses the power of spring tension and material elasticity. As rotation commences, frictional heat causes the lip to contract, enhancing the seal's efficacy; when stationary, it maintains contact, safeguarding the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals are widely deployed in engines, gearboxes, hydraulic pumps, reducers, and numerous other equipment types. They perform exceptionally well under high-temperature, high-speed, and corrosive conditions, surpassing the capabilities of traditional rubber oil seals. For instance, PTFE seals offer a lifespan up to 20 times longer, efficiently sealing water, acids, gases, and more.

[Selection and Installation of Oil Seals]
When selecting and installing oil seals, consider factors like the shaft's rotational speed, operational temperature, pressure, and medium characteristics. Ensure a vertical shaft installation to prevent tilting and apply grease to the lip to reduce the risk of dry grinding.
