Product Description

Oil seals, also known as rotary shaft seals, are quintessential components in any rotating or moving assembly. They epitomize excellence by sealing grease, liquids, or dirt with precision, thus meticulously ensuring the delicate balance between stationary and moving parts within mechanical equipment. An oil seal is artfully constructed from three pivotal elements:
The assembly boasts a sealing material, primarily a rubber component, fortified with robust metal casings and dependable springs, thus presenting a versatile sealing solution that adapts to various mechanical demands.
Our oil seal repertoire includes an array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, meticulously designed to meet a broad spectrum of sealing requirements.
Delve into our extensive range of premium rubber materials, crafted specifically for manufacturing high-performance oil seals. These materials are engineered to exhibit exceptional resilience against a multitude of chemicals and are capable of withstanding extreme temperatures, ranging from scorching highs to freezing lows.
[Introducing 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.

We specialize in the meticulous crafting of customizable non-standard oil seals, utilizing top-tier materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber to meet your precise specifications.

[Oil Seal Core Structure Types]

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

[Oil Seal and Its Sealing Principle]
The oil seal ingeniously forms an oil film through the precise contact between its lip and the shaft, utilizing the synergy of spring pressure and material elasticity. As rotation ensues, frictional heat prompts the lip to contract, thus fortifying the seal; while in a stationary state, it sustains contact, preserving the integrity of the seal seamlessly.

[Fields of Oil Seal Applications]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and other machinery. They are engineered to excel in high-temperature, high-speed, and corrosive environments, setting them apart from conventional rubber oil seals. Notably, PTFE seals possess a lifespan up to 20 times longer, effectively sealing water, acids, gases, and more with unmatched precision.

[Selection and Installation of Oil Seals]
Critical considerations include the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure meticulous vertical shaft installation to avert tilting, and apply grease to the lip to ameliorate dry grinding and enhance performance.
