Product Description

Oil seals, also known as rotary shaft seals, are pivotal components in any rotating or moving mechanical assembly. They adeptly seal in grease, prevent the intrusion of liquids or dirt, and expertly stabilize the interface between stationary and moving parts within mechanical equipment. An oil seal comprises three indispensable elements:
The assembly features a sealing material in the form of a resilient rubber component, sturdy metal casings, and dependable springs, offering a comprehensive and versatile sealing solution.
Our product range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, effectively addressing a wide spectrum of sealing requirements.
Discover our extensive array of premium rubber materials, meticulously crafted for producing high-performance oil seals. These materials are meticulously engineered to resist a broad range of chemical exposures and to withstand extreme temperature variations, 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 manufacturing customizable non-standard oil seals using superior-quality 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 generates an oil film through the precise interaction between its lip and the shaft. This dynamic sealing mechanism leverages both the pressure exerted by a spring and the inherent elasticity of the material. During rotation, the frictional heat causes the lip to contract, thereby reinforcing the seal; when stationary, it maintains contact, preserving the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and various other equipment. They are designed to excel in high-temperature, high-speed, and corrosive environments, providing superior performance compared to traditional rubber oil seals. Notably, PTFE seals offer a lifespan up to 20 times longer, efficiently sealing water, acids, gases, and more.

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