Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding mechanical assemblies by effectively sealing grease, liquids, or dirt. These indispensable components are integral to any rotating or moving assembly, ensuring stability by maintaining the crucial space between stationary and moving parts in mechanical equipment. Typically, an oil seal is constructed from three fundamental elements:
a sealing material (rubber component), metal casings, and springs, forming a versatile assembly that adapts seamlessly to diverse operational demands.
Our extensive range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, each crafted for specific applications and performance requirements.
We proudly offer an expansive selection of top-grade rubber materials for oil seal manufacturing that guarantees compatibility with a wide array of operating conditions. Our premium rubber materials boast high endurance against various chemicals and extreme temperatures, whether soaring or sub-zero.
[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 capability to produce customizable non-standard oil seals using specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber allows us to meet unique operational needs.

[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)

[Key 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

[Principle of Oil Seal Functionality]
The oil seal ingeniously forms an oil film through the contact between its lip and the shaft, achieving dynamic sealing by leveraging the spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, enhancing the seal; when stationary, it maintains contact to secure the seal's integrity.

[Oil Seal Application Areas]
Our oil seals find widespread application in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed environments or where traditional seals falter. Notably, PTFE oil seals can outlast conventional counterparts by up to 20 times and effectively seal water, acid, gas, and other challenging media.

[Selecting and Installing Oil Seals]
To ensure optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics holistically. Install the vertical shaft to avoid tilting and apply grease to the lip to minimize dry friction.
