Product Description

Oil seals, also known as rotary shaft seals, serve a crucial role in machinery, acting as the guardians against grease, liquids, or dirt, ensuring smooth and uninterrupted operation. These indispensable components stabilize the gap between stationary and moving parts in mechanical equipment, providing unmatched reliability and efficiency. Typically, an oil seal is composed of three essential elements:
The sealing assembly is a masterpiece of precision engineering, featuring a harmonious blend of sealing material (rubber component), robust metal casings, and resilient springs. This adaptable design stands as a testament to enduring durability and unwavering reliability.
Discover our comprehensive array of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the groundbreaking TC4, among many others.
Our collection of high-performance rubber materials for oil seals is unparalleled, meticulously engineered to endure a wide spectrum of chemicals and extreme temperatures. Crafted with precision, they excel under diverse operating conditions, whether braving intense heat or enduring the chill of low temperatures.
[Introduction to Oil Seal Materials]

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 distinct requirements, we provide customizable non-standard oil seals, crafted from advanced materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, delivering bespoke solutions tailored to your specific challenges.

[Core Structure Types of Oil Seals]

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 Oil Seals]

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

[Principle of Oil Sealing]
The oil seal functions on an intricate principle, forming an oil film through the dynamic interaction between the lip and the shaft. Utilizing spring pressure and the natural elasticity of materials, it ensures a robust seal. During operation, frictional heat causes the lip to contract, enhancing the seal's effectiveness, while in rest mode, it maintains its grip to ensure integrity.

[Fields of Application for Oil Seals]
Our oil seals are vital in engines, gearboxes, hydraulic pumps, reducers, and more. They thrive in high-temperature, high-speed, and corrosive environments where traditional seals might falter. Consider our PTFE oil seals, which offer longevity up to 20 times that of conventional seals, providing effective sealing for water, acids, gases, and beyond.

[Selection and Installation of Oil Seals]
When selecting and installing oil seals, take into account the shaft's rotation speed, temperature, pressure, and the characteristics of the medium. Ensure vertical installation to prevent tilting and apply grease to the lip to reduce dry grinding, thereby enhancing the seal's longevity and efficiency.
