Product Description

Oil seals, also known as rotary shaft seals, are the unsung heroes of rotating or moving assemblies, expertly sealing grease, keeping liquids contained, and blocking out dirt. They play a vital role in maintaining the delicate balance between stationary components and moving parts within mechanical equipment. Each oil seal is a marvel of engineering, composed of three critical elements that work in harmony:
The oil seal assembly is a masterpiece of design, featuring a resilient sealing material (a rubber component), fortified by robust metal casings and dependable springs. This trio creates a versatile and reliable sealing solution tailored to meet the demands of various applications.
Our product line boasts a wide array of types, including but not limited to: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4. Each type is carefully crafted to address a spectrum of sealing requirements, ensuring we have the perfect seal for every need.
Delve into our extensive range of premium rubber materials, expertly tailored for crafting high-performance oil seals. These materials are meticulously engineered to resist a diverse array of chemicals and withstand the challenges of 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 pride ourselves on our expertise in creating customizable, non-standard oil seals. Using only the finest materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, we deliver superior quality and durability in every seal.

[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 ingenious design of the oil seal allows it to create a protective oil film through the precise contact between its lip and the shaft. This dynamic interaction, powered by spring pressure and material elasticity, enhances sealing during rotation as frictional heat contracts the lip, while ensuring a steadfast seal when stationary.

[Fields of Oil Seal Applications]
Our oil seals find widespread application in engines, gearboxes, hydraulic pumps, reducers, and a host of other equipment. They are exceptionally suited for high-temperature, high-speed, and corrosive environments, often surpassing the performance of traditional rubber oil seals. PTFE seals, for instance, provide an impressive lifespan up to 20 times longer, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
When selecting and installing oil seals, consider the rotational speed of the shaft, along with temperature, pressure, and medium characteristics. Ensure a vertical installation to avoid shaft tilting and apply grease to the lip, reducing the risk of dry grinding, thus optimizing performance and longevity.
