Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in safeguarding your machinery's integrity. They proficiently seal grease, liquids, or prevent dirt intrusion, acting as indispensable guardians in any rotating or moving assembly. The oil seal, a vital component, stabilizes and maintains the delicate balance between stationary and moving parts within mechanical equipment. Typically, an oil seal is composed of three essential elements:
These elements include a sealing material (rubber component), metal casings, and springs, forming a highly adaptable and versatile sealing assembly.
Our range of types encompasses styles such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to varied needs.
We present a comprehensive selection of superior rubber materials for crafting oil seals, ensuring they meet the demands of diverse operating conditions. These premium rubber materials withstand exposure to a broad spectrum of chemicals and endure extreme temperatures, whether scorching high or freezing low.
[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.

Customizable non-standard oil seals are expertly crafted using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your specific 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 ingeniously creates an oil film via the contact between its lip and the shaft, achieving dynamic sealing through a synergy of spring pressure and material elasticity. During rotation, the lip contracts from frictional heat, enhancing the seal; while stationary, it maintains a firm contact to ensure lasting preservation of the seal.

[Oil seal application fields]
Oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and a plethora of other equipment—especially in high-temperature, high-speed, or corrosive media scenarios where traditional rubber oil seals falter. Notably, PTFE oil seals exhibit remarkable longevity, enduring up to 20 times longer than conventional ones and adeptly sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
Consider the shaft's rotation speed, temperature, pressure, and medium characteristics with a holistic approach. Ensure vertical shaft installation to avert tilting and apply grease to the lip as a preventive measure against dry grinding.
