Product Description

Oil seals, also known as rotary shaft seals, are vital components in any rotating or moving assembly. They expertly seal in grease, liquids, or dirt, precisely stabilizing the space between stationary and moving parts in mechanical equipment. An oil seal comprises three crucial elements:
The assembly features a sealing material (rubber component), robust metal casings, and dependable springs, offering a versatile and reliable sealing solution that adapts to various applications.
Our extensive range includes types like TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring we cater to the most diverse sealing requirements.
Discover our wide array of premium rubber materials, meticulously tailored for crafting high-performance oil seals. These materials are engineered to withstand exposure to various chemicals and endure extreme temperatures, 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 crafting customizable non-standard oil seals using top-quality materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring unmatched 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 forms an oil film through precise contact between its lip and the shaft, leveraging spring pressure and material elasticity for dynamic sealing. During rotation, frictional heat makes the lip contract, enhancing the seal; while stationary, it maintains contact, ensuring the seal's integrity remains intact.

[Fields of Oil Seal Applications]
Our oil seals are extensively employed in engines, gearboxes, hydraulic pumps, reducers, and more, excelling in high-temperature, high-speed, and corrosive environments. They outperform traditional rubber oil seals; PTFE seals, for instance, boast up to 20 times the lifespan, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
When selecting oil seals, consider factors like the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip for reduced friction and wear.
