Product Description

Oil seals, also known as rotary shaft seals, are indispensable in preventing the escape of grease, liquids, or the intrusion of dirt. They play a pivotal role in any rotating assembly by maintaining a seamless relationship between stationary and mobile components within mechanical machinery. An oil seal typically integrates three core elements to ensure flawless performance:
These core elements include a sealing material made of rubber, sturdy metal casings, and resilient springs. Together, they form a highly adaptable sealing assembly that functions optimally under various conditions.
Our diverse range of oil seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among many others, ensuring a perfect fit for every application.
We pride ourselves on offering an extensive array of rubber materials specifically chosen for crafting oil seals that meet diverse operational demands. Our superior rubber materials withstand a wide spectrum of chemicals and endure both extremely high and low temperatures with unwavering reliability.
[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.

For custom solutions, we fabricate non-standard oil seals from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailoring them to meet specific needs and challenge any operational constraint.

[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 forms an oil film at the interface of the lip and the shaft, creating a dynamic seal through the synergy of spring force and material resilience. During rotation, frictional heat causes the lip to contract, enhancing the sealing efficacy, while when at rest, it maintains a firm grip to secure the seal.

[Oil Seal Application Fields]
These oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, particularly where conditions are extreme: high temperatures, rapid speeds, corrosive environments, or where traditional seals fail. Our PTFE oil seals, for example, outlast standard options by up to 20 times and effectively handle sealing for water, acid, gas, and varied media.

[Oil Seal Selection and Installation]
It is imperative to thoroughly evaluate shaft rotation speed, temperature, pressure, and medium characteristics. Ensure vertical installation to avoid tilting, while applying grease to the lip to minimize friction and wear during operation.
