Product Description

Oil seals, or rotary shaft seals, hold a pivotal role in any rotating or moving assembly. These superior seals expertly secure grease, liquids, or dirt, meticulously maintaining equilibrium between stationary and moving components within mechanical systems. An oil seal comprises three vital elements:
This assembly features a sealing material (rubber component), robust metal casings, and dependable springs, delivering a versatile and durable sealing solution.
We offer a variety of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to meet a wide range of sealing requirements.
Discover our extensive array of premium rubber materials, specifically crafted for manufacturing high-performance oil seals. These materials are expertly engineered to resist a vast spectrum of chemicals and endure extreme temperature fluctuations, 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 the craftsmanship of customizable non-standard oil seals, utilizing high-quality materials like 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 forms an oil film through precise contact between its lip and the shaft. This dynamic sealing process harnesses spring pressure and the inherent elasticity of the materials. During rotation, the frictional heat causes the lip to contract, thereby 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 various other equipment. They excel in high-temperature, high-speed, and corrosive environments, significantly outperforming conventional rubber oil seals. For example, PTFE seals offer up to 20 times the durability, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
Take into account the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to avert tilting and apply grease to the lip to reduce dry grinding.
