Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in mechanical assemblies by sealing grease, liquids, or dirt. These indispensable components stabilize the gap between stationary and moving parts, ensuring smooth operation in any rotating or moving assembly. An oil seal typically comprises three core elements that work in harmony:
A meticulously designed sealing material (rubber component), robust metal casings, and resilient springs. This combination forms a versatile sealing assembly that meets the demands of various applications.
Our extensive range of types includes options such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, catering to diverse sealing needs.
We provide an impressive array of rubber materials for crafting oil seals, ensuring compatibility across a wide spectrum of operating conditions. These high-performance materials withstand a variety of chemicals and endure extreme temperature ranges, both high and low.
[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.

Our customizable non-standard oil seals are crafted using premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific requirements.

[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)

[Essential 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

[Oil Seal and Its Sealing Principle]
Achieving dynamic sealing, the oil seal forms an oil film where the lip contacts the shaft, harnessing spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing sealing efficiency; when static, it sustains contact to maintain the seal.

[Fields of Oil Seal Application]
Our oil seals are extensively deployed in engines, gearboxes, hydraulic pumps, reducers, and more, excelling in high temperature, high speed, and corrosive environments where traditional seals fall short. Notably, PTFE oil seals can last 20 times longer, effectively sealing water, acid, gas, and other challenging media.

[Oil Seal Selection and Installation Guidelines]
When selecting oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical shaft is properly installed to avoid tilting, and apply grease to the lip to minimize dry grinding and enhance seal longevity.
