Product Description

Oil seals, also known as rotary shaft seals, are the unsung heroes in any rotating or moving assembly. They expertly seal grease, liquids, or dirt, ensuring the flawless separation between stationary and moving parts within mechanical equipment. An oil seal is thoughtfully crafted from three fundamental elements:
The assembly features a top-quality sealing material (rubber component), durable metal casings, and dependable springs, creating a versatile and robust sealing solution.
Our diverse range includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed to meet a wide variety of sealing requirements with precision.
Embark on a journey through our vast collection of superior rubber materials, meticulously selected for the creation of high-performance oil seals. These materials are scientifically engineered to resist a wide range of chemicals and withstand both extremely high and low temperatures.
[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 tailor-made non-standard oil seals, utilizing premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring quality and durability.

[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 creates a protective oil film through the precise interaction between its lip and the shaft. This dynamic sealing process harnesses spring pressure and the elasticity of materials. As rotation occurs, frictional heat causes the lip to contract, enhancing the seal; while at rest, it maintains contact to preserve the seal's integrity.

[Fields of Oil Seal Applications]
Renowned for their versatility, our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more. They thrive in environments characterized by high temperatures, high speeds, and corrosive conditions, surpassing conventional rubber oil seals. Notably, PTFE seals offer up to 20 times the lifespan, providing effective seals against water, acids, gases, and more.

[Selection and Installation of Oil Seals]
When selecting oil seals, consider crucial factors like the shaft's rotational speed, operating temperature, pressure, and the characteristics of the medium. Proper vertical shaft installation is vital to avoid tilting, and applying grease to the lip is recommended to reduce dry grinding.
