Product Description

Oil seals, also known as rotary shaft seals, are pivotal to the seamless functioning of mechanical systems. Tasked with the crucial role of sealing grease, liquids, or dirt, they are indispensable in any rotating and moving assembly. Their primary function is to stabilize the space between the stationary and moving components of mechanical equipment. Typically, an oil seal is comprised of three fundamental elements:
A sealing material, which includes a resilient rubber component, robust metal casings, and durable springs, making it a multifaceted and highly efficient sealing assembly.
Our diverse range of oil seal types includes the versatile TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others.
We pride ourselves on offering an extensive selection of premium rubber materials for crafting oil seals, ensuring adaptability for varied operating conditions. These exceptional rubber materials are engineered to withstand an array of chemicals and extreme temperatures, from the highest to the lowest.
[Comprehensive 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.

Our customizable non-standard oil seals can be expertly crafted using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring bespoke solutions.

[Detailed Examination of Oil Seal Core Structure 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 Advanced Oil Seals]

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

[Understanding the Principle of Oil Sealing]
The oil seal ingeniously forms an effective oil film through the contact between its precision-engineered lip and the shaft, achieving dynamic sealing. This is accomplished through the strategic use of spring pressure and the inherent elasticity of the material. During rotation, the lip contracts due to frictional heat, thereby amplifying the sealing capability; when stationary, it maintains a firm contact to ensure the seal's integrity.

[Diverse Application Fields for Our High-Performance Oil Seals]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, particularly in challenging scenarios involving high temperatures, high speeds, and corrosive media, where traditional rubber oil seals falter. For instance, our PTFE oil seals deliver a lifespan up to 20 times longer than conventional seals and excel at sealing water, acid, gas, and other aggressive media.

[Guidelines for Oil Seal Selection and Installation]
When selecting and installing oil seals, it's imperative to consider the shaft's rotation speed, the temperature, the pressure, and the medium characteristics. Ensure the installation of the shaft is vertical to prevent tilting and apply a suitable grease to the lip to minimize dry grinding.
