Product Description

Oil seals, the silent sentinels of machinery, operate with precision to expertly guard against leaks of grease, liquids, and dirt, ensuring the seamless performance of mechanical marvels. These indispensable components bridge the gap between stationary and dynamic parts, maintaining stability and enhancing efficiency. Typically, an oil seal is a symphony of three essential components:
The sealing assembly is a testament to engineering excellence, incorporating a robust sealing material (rubber component), fortified metal casings, and resilient springs. This adaptable design epitomizes unmatched durability and steadfast reliability.
Delve into our extensive selection featuring diverse types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the groundbreaking TC4, among others.
At the pinnacle of performance, our rubber materials for oil seals are unparalleled, meticulously engineered to withstand a wide array of harsh chemicals and extreme temperatures. Crafted with precision, they excel under diverse operating conditions, whether confronting searing heat or enduring the biting cold.
[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.

For those seeking tailored solutions, we present customizable non-standard oil seals, expertly fashioned from specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring perfect solutions for your specific challenges.

[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 operates on a refined principle, generating a protective oil film through the dynamic interplay between the lip and the shaft. Harnessing the power of spring pressure and the intrinsic elasticity of the materials, it ensures a formidable seal. During operation, frictional heat causes the lip to contract, enhancing the seal, while at rest, it steadfastly maintains its grip to secure integrity.

[Oil seal application fields]
Our oil seals are indispensable champions in engines, gearboxes, hydraulic pumps, reducers, and beyond. They triumph in high-temperature, high-speed, and corrosive environments where conventional seals might falter. Consider our PTFE oil seals, which boast a lifespan up to 20 times longer than traditional seals, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. Ensure vertical installation to prevent tilting and apply grease to the lip to mitigate dry grinding, thereby extending the seal's lifespan and efficacy.
