Product Description

Oil seals, often known as rotary shaft seals, are indispensable components designed to efficiently seal grease, liquids, or dirt. As a crucial part of any rotating and moving assembly, the oil seal brilliantly stabilizes the space between stationary and moving parts in mechanical equipment. Typically, an oil seal is composed of three key elements that define its performance and reliability:
A trifecta of sealing excellence: the flexible sealing material (rubber component), durable metal casings, and resilient springs. Together, they form a versatile sealing assembly that meets diverse industrial needs.
Our extensive catalogue includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, enabling you to find the perfect match for each application.
We proudly offer an array of superior rubber materials for crafting oil seals, ensuring they meet a variety of demanding operating conditions. These high-performance materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, both high and low, making them an ideal choice for various industrial challenges.
[Comprehensive Overview of 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 customizable non-standard oil seals are expertly crafted using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering tailored solutions for unique requirements.

[Exploration of Oil Seal Core Structural 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

[Innovative Oil Seal and Sealing Principles Explained]
The oil seal ingeniously creates a protective oil film through the precise contact between the lip and the shaft. This dynamic sealing is achieved by harmonizing spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal; when stationary, it maintains firm contact to preserve sealing integrity.

[Diverse Application Fields for Oil Seals]
Our oil seals find wide-ranging applications in engines, gearboxes, hydraulic pumps, reducers, and more, particularly excelling in high-temperature, high-speed, or corrosive environments where traditional rubber oil seals falter. For instance, PTFE oil seals boast up to 20 times the longevity of conventional options and proficiently seal water, acid, gas, and various challenging media.

[Guidelines for Oil Seal Selection and Installation]
Considerations such as rotation speed, temperature, pressure, and medium characteristics of the shaft are crucial. Ensure vertical shaft installation for optimal performance, prevent tilting, and apply grease to the lip to mitigate dry grinding.
