Product Description

Oil seals, also known as rotary shaft seals, serve as the ultimate guardians for keeping grease, liquids, and dirt at bay. As vital components of any rotating or moving assembly, oil seals play a crucial role in stabilizing the delicate balance between stationary and moving parts within mechanical equipment. Typically crafted with precision, an oil seal comprises three essential elements:
These elements include a sealing material specifically made of a robust rubber component, metal casings, and precisely engineered springs. Together, they form a highly adaptable sealing assembly.
Our extensive range of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among other versatile options.
We proudly offer an extensive array of rubber materials tailored for crafting superior oil seals, ensuring their perfect suitability across diverse operating conditions. Our high-performance rubber materials are designed to withstand a wide array of chemicals and endure extreme temperatures, whether blisteringly high or bone-chillingly low.
[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 offerings include customizable non-standard oil seals, which can be meticulously crafted using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[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 oil seal ingeniously creates a protective oil film through the intricate contact between the lip and the shaft, achieving dynamic sealing by leveraging the power of spring pressure and material elasticity. Upon rotation, the lip contracts due to frictional heat, thereby amplifying the sealing effect. When still, it steadfastly maintains contact to preserve the integrity of the seal.

[Oil seal application fields]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and a multitude of other equipment. They shine particularly in high-temperature, high-speed, or corrosive environments where conventional rubber oil seals fall short. For example, our PTFE oil seals boast an impressive lifespan, outlasting traditional seals by up to 20 times and excelling in sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, it is imperative to consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. Ensure the vertical shaft is properly installed to prevent tilting, and apply grease to the lip to mitigate dry grinding, ensuring longevity and reliability.
