Product Description

Product Description

Oil seals, also known as rotary shaft seals, are pivotal in maintaining the integrity of mechanical assemblies by effectively sealing grease, liquids, or dirt. These indispensable components ensure a stable interface between stationary and dynamic parts, optimizing the performance of any rotating and moving assembly. The typical oil seal comprises three essential elements that work in harmony:
A robust sealing material, usually a rubber component, complemented by durable metal casings and reliable springs, makes for a versatile sealing assembly suitable for diverse applications.
Our product range includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide array of sealing demands.
We pride ourselves on offering an extensive selection of high-performance rubber materials for oil seals, designed to meet and exceed the demands of a variety of operating conditions. These materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, ensuring reliability and durability regardless of the environment.
[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.

We specialize in producing customizable non-standard oil seals using a range of materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, each selected for their unique properties and suitability for specialized applications.

[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 functions by forming an oil film through the precise contact between the lip and the shaft, thus attaining dynamic sealing. This is achieved by leveraging the pressure from springs and the material's inherent elasticity. During rotation, the lip's contraction due to frictional heat enhances sealing efficiency; when stationary, it maintains a secure seal to prevent leakage.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and other crucial equipment, excelling in environments characterized by high temperatures, rapid speeds, and corrosive media. Ideal for scenarios where conventional rubber oil seals underperform, PTFE oil seals surpass traditional counterparts, offering longevity up to 20 times greater and the ability to seal water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, it's vital to thoroughly assess the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical installation of the shaft to prevent tilt and apply grease to the lip to mitigate dry grinding, ensuring seamless operation and extended lifespan.
