Product Description

Oil seals, also known as rotary shaft seals, are vital components in any assembly with moving or rotating parts. They expertly seal in grease, fluids, and prevent dirt intrusion, ensuring seamless interaction between stationary and mobile components within mechanical systems. Each oil seal is constructed with three fundamental elements:
This assembly consists of a high-quality sealing material (rubber component), durable metal casings, and reliable springs, providing an adaptable and robust sealing solution.
Our range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, amongst others, designed to meet a wide array of sealing requirements.
Discover our comprehensive selection of top-tier rubber materials, specifically designed for the production of high-performance oil seals. These materials are crafted to resist a diverse array of 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 premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber to ensure superior quality 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 creates an oil film through precise contact between its lip and the shaft. This sophisticated sealing mechanism utilizes spring pressure and material elasticity. During rotation, friction-induced heat prompts the lip to contract, enhancing the seal; while stationary, it maintains contact to uphold seal integrity.

[Fields of Oil Seal Applications]
Widely employed in engines, gearboxes, hydraulic pumps, reducers, and numerous other devices, our oil seals perform exceptionally in high-temperature, high-speed, and corrosive environments. They surpass conventional rubber oil seals, with PTFE seals offering up to 20 times longer lifespan, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
Take into account factors like shaft rotational speed, temperature, pressure, and medium characteristics. Ensure the shaft is installed vertically to avoid tilting issues, and apply grease to the lip to reduce the risk of dry grinding.
