Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding machinery from grease, liquids, and dirt intrusions. These indispensable components stabilize the interface between the stationary and moving parts of mechanical assemblies, ensuring seamless operation. Comprising three primary elements, the oil seal is the unsung hero of smooth functionality:
Crafted with precision, an oil seal assembly includes a highly adaptable rubber component, robust metal casings, and resilient springs, making it a versatile sealing solution for myriad applications.
Explore our extensive range of types, including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, designed to meet diverse needs and requirements.
We present an extensive array of rubber materials curated for crafting oil seals that are adept for varied operational scenarios. Our high-performance options endure exposure to diverse chemicals and withstand extreme temperatures, both scorching highs and chilling lows.
[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.

Customize your non-standard oil seals with cutting-edge materials such as fluorine rubber, silicone rubber, finely engineered rubber, and propylene rubber, tailored to your exact specifications.

[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 ingenious design of the oil seal forms an effective oil film at the lip-shaft interface, attaining dynamic sealing through the synergy of spring pressure and material elasticity. As the shaft rotates, frictional heat causes the lip to contract, intensifying the seal; when stationary, the lip maintains contact, preserving the integrity of the seal.

[Oil seal application fields]
Our oil seals find their place in engines, gearboxes, hydraulic pumps, reducers, and more, especially in high-stress conditions like elevated temperatures, rapid speeds, and corrosive environments. Notably, PTFE oil seals surpass conventional seals with a lifespan up to 20 times longer, adept at sealing water, acids, gases, and beyond.

[Oil seal selection and installation]
A comprehensive evaluation of rotation speed, temperature, pressure, and shaft medium characteristics is crucial. Ensure the vertical installation of the shaft to prevent tilting and apply grease on the lip to minimize dry friction, extending seal longevity.
