Product Description

Oil seals, often known as rotary shaft seals, are indispensable for maintaining the integrity of grease, liquids, or dirt in mechanical systems. These vital components stabilize the gap between static and dynamic elements within machinery, ensuring seamless operation. Typically, an oil seal is composed of three core components:
The assembly features a sealing material like a rubber component, along with metal casings and springs, making it exceptionally versatile and adaptable to a multitude of applications.
Explore a wide variety of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to meet the specific needs of different mechanical systems.
Our extensive selection of rubber materials is crafted to suit diverse operational conditions, offering exceptional performance. These materials withstand a broad spectrum of chemicals and handle extreme temperatures with ease, whether soaring high or freezing low.
[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.

We offer customizable non-standard oil seals using premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber to meet unique application requirements.

[Core Structure Types of Oil Seal]

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 Elements of 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

[Principle of Oil Seal and Sealing Mechanism]
By forming an oil film at the lip-shaft interface, the oil seal achieves dynamic sealing. Utilizing spring pressure and material elasticity, the lip contracts with frictional heat during rotation to strengthen the seal, while maintaining contact when stationary to prevent leaks.

[Applications of Oil Seals]
Utilized across engines, gearboxes, hydraulic pumps, and reducers, especially under high temperatures, high speeds, and corrosive media. In cases where traditional seals face challenges, PTFE oil seals outperform, lasting up to 20 times longer and sealing water, acids, gases, and more with exceptional reliability.

[Selection and Installation of Oil Seals]
A thorough evaluation of shaft rotation speed, temperature, pressure, and medium characteristics is crucial. Ensure vertical installation without tilts and apply grease to the lip to reduce friction for optimal performance.
