Product Description

Oil seals, also known as rotary shaft seals, are vital components in any rotating or moving mechanical assembly. They expertly seal grease, liquids, or dirt, ensuring seamless stability between stationary and moving parts. An oil seal is artfully crafted from three indispensable elements:
The assembly is composed of a sealing material (rubber component), dependable metal casings, and sturdy springs, creating a multifaceted and reliable sealing solution.
Our comprehensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, meeting a wide array of sealing requirements.
Delve into our extensive array of top-tier rubber materials, meticulously designed for crafting high-performance oil seals. These materials are engineered to resist a broad spectrum of chemicals and endure extreme thermal conditions.
[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 specialize in the creation of tailored non-standard oil seals utilizing top-of-the-line materials including fluorine rubber, silicone rubber, fine 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 innovative sealing process harnesses spring tension and material flexibility. During rotation, the generated frictional heat causes the lip to contract, enhancing the seal, while at rest, it maintains contact, ensuring the seal's enduring integrity.

[Fields of Oil Seal Applications]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and beyond. They thrive in high-temperature, high-speed, and corrosive environments, surpassing traditional rubber oil seals. For instance, PTFE seals boast up to 20 times the lifespan, providing exceptional sealing for water, acids, gases, and more.

[Selection and Installation of Oil Seals]
Evaluate the shaft's speed, temperature, pressure, and medium characteristics. Ensure vertical installation of the shaft to prevent misalignment, and apply grease to the lip to reduce dry friction.
