Product Description

Oil seals, or rotary shaft seals, are the unsung heroes in any rotating or moving assembly. Their superior design allows them to skillfully seal grease, liquids, and dirt, ensuring a meticulous balance between stationary and moving parts within mechanical equipment. An oil seal is comprised of three vital components:
This assembly includes a durable sealing material (rubber component), robust metal casings, and dependable springs, delivering a versatile and reliable sealing solution that meets diverse operational demands.
Our extensive product range features types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each expertly designed to satisfy a wide array of sealing requirements.
Discover our wide assortment of premium rubber materials, expertly engineered for crafting high-performance oil seals. These materials are meticulously designed to resist various chemicals and endure extreme temperatures, both scorching and icy.
[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 take pride in our expertise in manufacturing customizable non-standard oil seals, utilizing top-tier materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific customer requirements.

[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 efficient oil film through precise lip-to-shaft contact. This sophisticated dynamic sealing relies on spring pressure and material elasticity. During rotation, friction-induced heat causes the lip to contract, enhancing the seal; when stationary, it maintains contact, safeguarding the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals are the preferred choice in engines, gearboxes, hydraulic pumps, reducers, and more. They perform excellently in high-temperature, high-speed, and corrosive environments, surpassing conventional rubber oil seals. For example, PTFE seals boast a lifespan up to 20 times longer, effectively sealing water, acid, gas, and other substances.

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