Product Description

Oil seals, often referred to as rotary shaft seals, are indispensable components in any equipment featuring rotating or moving assemblies. They expertly seal grease, liquids, or dirt, ensuring a seamless barrier between stationary and dynamic elements of mechanical equipment. An oil seal is meticulously crafted from three core components:
This assembly is thoughtfully designed with a sealing material (rubber component), durable metal casings, and dependable springs, providing a multifaceted sealing solution.
Our diverse range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to address a wide array of sealing requirements.
Delve into our comprehensive selection of superior rubber materials, precisely tailored for crafting high-performance oil seals. These materials are specifically engineered to resist a broad spectrum of chemicals and withstand 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 take pride in specializing in the creation of customizable non-standard oil seals using top-tier 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 ingeniously crafts an oil film through the precise interface between its lip and the shaft. This dynamic sealing is further enhanced by spring pressure and material elasticity. As the shaft rotates, frictional heat induces contraction of the lip, thereby fortifying the seal. When stationary, the seal maintains contact, safeguarding its integrity.

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

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