Product Description

Oil seals, often revered as rotary shaft seals, embody the relentless champions of machinery, tirelessly working behind the scenes to masterfully seal grease, liquids, or dirt, ensuring operations that are consistently smooth and flawless. These critical components maintain stability between stationary and moving elements of mechanical equipment, promising unwavering reliability and peak efficiency. Generally, an oil seal consists of three essential elements, each playing a pivotal role in its vital functionality:
The sealing assembly stands as a marvel of contemporary engineering, meticulously crafted from a blend of sealing material (rubber component), robust metal casings, and resilient springs. This ingenious and versatile design epitomizes durability, reliability, and lasting performance, making it a cornerstone of modern machinery.
Dive into our expansive and diverse selection of premium types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the groundbreaking TC4, among others. Each is meticulously engineered to meet a broad spectrum of application demands.
Our unparalleled selection of high-performance rubber materials for oil seals is expertly engineered to withstand a multitude of chemicals and endure extreme temperatures. These materials are crafted with precision to deliver excellent performance across various operating conditions, whether confronting the searing heat of high temperatures or the chilling cold of low temperatures.
[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 with exceptional needs, we offer customizable non-standard oil seals, masterfully crafted from specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber. These bespoke solutions are tailored to address and conquer your unique challenges and requirements.

[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 an intricate and ingenious principle, forming an effective oil film through the dynamic interplay between the lip and the shaft. Leveraging the precise pressure of springs and the intrinsic elasticity of the materials, it ensures an extraordinarily robust seal. During operation, the frictional heat causes the lip to contract, thereby amplifying the seal, while in rest mode, it maintains a firm grip to ensure integrity and reliability.

[Oil seal application fields]
Our oil seals are crucial in engines, gearboxes, hydraulic pumps, reducers, and beyond. They thrive even in high-temperature, high-speed, and corrosive environments, where conventional seals might struggle. Explore our PTFE oil seals, which boast a lifespan exceeding up to 20 times that of traditional seals, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When choosing and installing oil seals, it is essential to consider factors like the shaft's rotation speed, ambient temperature, pressure, and medium characteristics. Ensure precise vertical installation to avoid tilting, and generously apply grease to the lip to prevent dry grinding, thus extending the seal's lifespan and optimizing its efficiency.
