Product Description

Oil seals, known as rotary shaft seals, play a vital role in any rotating or moving assembly. They expertly seal grease, liquids, or dirt, ensuring optimal stability between stationary and moving components in mechanical equipment. An oil seal is crafted from three pivotal elements:
The assembly features a high-quality sealing material (rubber component), robust metal casings, and reliable springs, providing a comprehensive and adaptable sealing solution.
Our product range includes diverse types like TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, expertly designed to meet varied sealing demands.
Discover our expansive array of premium rubber materials, meticulously tailored for crafting high-performance oil seals. These innovative materials are engineered to resist a vast spectrum of chemicals and withstand 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 specialize in creating customizable non-standard oil seals with exceptional quality materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring unmatched durability 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 meticulously forms an oil film through precise lip-to-shaft contact. This dynamic sealing utilizes spring pressure and material elasticity. During rotation, the frictional heat causes the lip to contract, enhancing the seal; when stationary, 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 more. They excel in high-temperature, high-speed, and corrosive environments, surpassing traditional rubber oil seals. For instance, PTFE seals deliver up to 20 times the lifespan, efficiently sealing water, acid, gas, and other elements.

[Selection and Installation of Oil Seals]
Consider factors such as the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to reduce dry grinding.
