Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in safeguarding machinery by effectively sealing grease, liquids, or dirt. As indispensable components in any rotating or moving assembly, they harmoniously stabilize the space between stationary and dynamic parts within mechanical equipment. An oil seal is typically comprised of three integral components:
Crafted with precision, these oil seals feature a robust sealing material (rubber component), durable metal casings, and resilient springs, forming a versatile and reliable sealing assembly.
Our extensive range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse sealing needs.
We proudly offer an extensive selection of high-performance rubber materials for crafting oil seals, ensuring compatibility with varied operational conditions. These exceptional rubbers withstand a spectrum of chemicals and thrive under extreme temperature conditions, both high and low.
[Introduction to 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.

Our expertise extends to crafting customizable non-standard oil seals utilizing premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific requirements.

[Core Structure Types of Oil Seals]

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 Oil Seals]

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

[Principles of Oil Sealing]
The sophisticated design of the oil seal facilitates the creation of a protective oil film through the intimate contact between the lip and the shaft. This dynamic sealing effect is achieved using the synergy of spring pressure and material elasticity. During rotation, the lip tightens, thanks to frictional heat, further enhancing the seal; when stationary, it maintains its grip to ensure continued protection.

[Application Fields for Oil Seals]
Our oil seals have found widespread application in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in challenging environments characterized by high temperatures, high speeds, corrosive media, or where traditional rubber seals fall short. For instance, PTFE oil seals boast longevity up to 20 times that of conventional seals, proficiently sealing water, acid, gas, and more.

[Oil Seal Selection and Installation Guidelines]
When selecting and installing oil seals, it is vital to consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. Ensure the vertical installation of the shaft to prevent tilting, and apply grease to the lip to minimize dry grinding.
