Product Description

Oil seals, also known as rotary shaft seals, are crucial components designed to keep out grease, liquids, and dirt. These indispensable elements stabilize and seal the space between stationary and moving parts in mechanical systems. Typically, an oil seal is ingeniously constructed with three fundamental components:
These components include a resilient sealing material (the rubber part), robust metal casings, and tension springs. Together, they create a versatile sealing solution that adapts to a variety of applications.
The diverse types of oil seals available include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among many others, ensuring a perfect fit for every need.
Our extensive range of premium rubber materials is specifically selected for manufacturing oil seals that meet the rigorous demands of various operating conditions. These high-grade materials are engineered to withstand a wide array of chemicals and temperature extremes, ensuring unparalleled performance and durability.
[An Insight into 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 requiring customizable solutions, we offer non-standard oil seals crafted from specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet unique application requirements.

[Diverse Oil Seal Core Structures]

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)

[Essential Structural Elements 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

[The Science Behind Oil Sealing Mechanisms]
Oil seals deftly create an oil film through the dynamic interaction between the lip and the shaft. Utilizing the combination of spring tension and material elasticity, they achieve superior dynamic sealing. As the shaft rotates, frictional heat causes the lip to contract, enhancing the seal. When stationary, the seal remains intact, ensuring continuous protection.

[Expansive Oil Seal Application Areas]
Our oil seals are extensively utilized in a variety of critical applications such as engines, gearboxes, hydraulic pumps, and reducers. They excel in challenging environments of high temperatures, high speeds, and corrosive media, where traditional seals may falter. Notably, PTFE oil seals boast durability, lasting up to 20 times longer than conventional types, and can effectively seal water, acid, gas, and more.

[Guidelines for Oil Seal Selection and Installation]
When choosing and installing oil seals, consider the shaft’s rotation speed, temperature, pressure, and medium characteristics comprehensively. Ensure vertical shaft installation to avoid tilting, and apply grease to the lip to minimize dry grinding, optimizing performance and longevity.
