Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding mechanical systems. They effectively seal grease, liquids, and prevent dirt intrusion, ensuring the integrity of moving assemblies. These indispensable components bridge the gap between stationary and moving parts, providing stability across various mechanical equipment. Typically, an oil seal is comprised of three core elements:
A sealing material (rubber component), metal casings, and springs. These elements coalesce to form a highly adaptable sealing assembly.
Our range includes diverse types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others.
We proudly offer a wide array of premium rubber materials crafted for oil seal manufacturing. Each material is meticulously chosen to suit a spectrum of operating conditions, enduring harsh chemicals and extreme temperatures, whether soaring or plummeting.
[Oil seal material introduction]

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 customizable non-standard oil seals are crafted from advanced materials including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring versatility and performance.

[Oil seal core structure type]

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)

[Key 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 sealing principle]
The innovative design of our oil seal forms an oil film through the precise interaction between the lip and the shaft. This dynamic sealing mechanism leverages spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal; while stationary, it retains contact to secure the sealing efficacy.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more. They thrive under high temperatures, high speeds, and corrosive environments where conventional seals may falter. Notably, PTFE oil seals boast longevity up to 20 times that of standard seals, proficiently sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
Selecting and installing oil seals demands careful consideration of factors like shaft speed, temperature, pressure, and medium properties. To ensure optimal performance, install the shaft vertically to avoid tilting and apply grease to the lip, minimizing friction and wear.
