Product Description

Oil seals, also known as rotary shaft seals, are essential components in any rotating or moving assembly. They expertly seal grease, liquids, or dirt, ensuring the stability and protection of the space between stationary and moving parts in mechanical equipment. An oil seal is composed of three critical elements:
The assembly features a sealing material (rubber component), strong metal casings, and dependable springs, providing a comprehensive and versatile sealing solution.
We offer a diverse array of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed to meet a wide range of sealing needs.
Discover our vast selection of superior rubber materials, specifically designed for crafting high-performance oil seals. These materials are engineered to endure a wide spectrum of chemicals and withstand both extreme 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 customizable non-standard oil seals using top-grade materials such as 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 creates an oil film through the precise contact between its lip and the shaft. This dynamic sealing mechanism utilizes spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, tightening the seal; while stationary, it remains in contact, maintaining the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and other equipment. They excel in high-temperature, high-speed, and corrosive environments, often outperforming traditional rubber oil seals. Notably, PTFE seals can offer up to 20 times the lifespan, effectively sealing water, acid, gas, and much more.

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