Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in the seamless operation of mechanical assemblies. These vital components are indispensable in sealing grease, liquids, or debris, maintaining the integrity of the space between stationary and mobile parts. Typically, an oil seal comprises three fundamental elements:
A sealing material made of resilient rubber, supported by robust metal casings and durable springs, forms a versatile sealing assembly that meets diverse requirements.
Our range includes varied types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among several others, catering to a wide array of applications.
We proudly offer an extensive selection of premium rubber materials for crafting oil seals, ensuring they are tailored to various operational demands. These high-performance materials are adept at withstanding a spectrum of chemicals and temperature extremes, 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 advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to unique specifications.

[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 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

[Principle of oil seal functioning]
The oil seal ingeniously forms an oil film through the strategic contact between its lip and the shaft. This dynamic sealing process is driven by the spring’s pressure and the material’s elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal; when stationary, it maintains contact to ensure a steadfast seal.

[Fields of application for oil seals]
Our oil seals are widely employed in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in extreme conditions involving high temperatures, high speeds, and corrosive environments, where traditional rubber seals falter. Notably, PTFE oil seals offer durability up to 20 times longer than conventional seals, adeptly sealing water, acids, gas, and other challenging media.

[Guidelines for oil seal selection and installation]
For optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium properties. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry friction.
