Product Description

Often hailed as rotary shaft seals, oil seals play a pivotal role in safeguarding machinery by effectively sealing out grease, liquids, or contaminants. These essential components are integral to any rotating or moving assembly, ensuring seamless operation by stabilizing the gap between stationary and dynamic parts. An oil seal typically comprises three core elements:
The versatile sealing assembly of oil seals includes a robust sealing material (rubber component), fortified metal casings, and resilient springs.
Our extensive range of oil seal types includes the widely utilized TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among others.
We pride ourselves on offering a vast selection of high-performance rubber materials for the crafting of oil seals, tailored to withstand various operational demands. These innovative materials are engineered to resist an array of chemicals and endure extreme temperatures, ensuring reliability in both scorching heat and biting cold.
[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.

Our customizable non-standard oil seals are meticulously crafted from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring unmatched durability and resilience.

[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's brilliance lies in its ability to form an oil film via the strategic contact between its lip and the shaft. By harnessing the power of spring pressure and material elasticity, it achieves optimal dynamic sealing. During rotation, the lip's contraction from frictional heat enhances its sealing prowess, while when idle, it maintains crucial contact to uphold the seal's integrity.

[Oil Seal Application Fields]
Our oil seals are indispensable across a myriad of applications, from engines and gearboxes to hydraulic pumps and reducers. They excel in challenging conditions, including high temperatures, swift speeds, corrosive environments, or where traditional rubber oil seals falter. Notably, PTFE oil seals boast a longevity up to 20 times that of conventional variants and adeptly seal diverse media such as water, acids, and gases.

[Oil Seal Selection and Installation]
When selecting and installing oil seals, it's crucial to consider the shaft's rotation speed, temperature, pressure, and medium characteristics holistically. Ensure a vertical shaft installation to avert tilting and apply grease to the lip to mitigate dry grinding and enhance longevity.
