Product Description

Oil seals, also known as rotary shaft seals, are vital components in any rotating or moving assembly. They elegantly and effectively seal grease, liquids, or dirt, ensuring the utmost stability in the space between stationary and moving parts of mechanical equipment. An oil seal is ingeniously designed with three fundamental elements:
This sophisticated assembly consists of a sealing material (the rubber component), sturdy metal casings, and dependable springs, presenting a versatile and robust solution for all sealing requirements.
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 diverse sealing demands.
Discover our vast array of premium rubber materials, meticulously designed for the creation of high-performance oil seals. These cutting-edge materials are engineered to resist a broad spectrum of chemicals and endure the most extreme temperatures, both scorching and freezing.
[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 are experts in crafting customizable non-standard oil seals, utilizing top-tier materials such as 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 ingeniously crafts an oil film through meticulous contact between its lip and the shaft. This dynamic sealing process relies on spring pressure and the elasticity of the material. During rotation, frictional heat causes the lip to contract, intensifying the seal; when stationary, it maintains contact, preserving the seal's formidable integrity.

[Fields of Oil Seal Applications]
Our oil seals are prominently utilized in engines, gearboxes, hydraulic pumps, reducers, and various other equipment. They excel in high-temperature, high-speed, and corrosive environments, surpassing the performance of traditional rubber oil seals. For example, PTFE seals offer an impressive lifespan of up to 20 times longer, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
When selecting, consider the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to mitigate dry grinding.
