Product Description

Oil seals, also known as rotary shaft seals, are vital components in machinery, expertly designed to prevent the leakage of grease, liquids, or dirt. As indispensable parts of rotating and moving assemblies, they play a crucial role by stabilizing the space between stationary and dynamic components in mechanical equipment. The standard oil seal comprises three critical elements:
The oil seal assembly includes a sealing material, typically a robust rubber component, alongside metal casings and reliable springs. This versatile design ensures an exceptional sealing performance across a multitude of applications.
Our range of oil seals features various types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed for specific uses.
We proudly offer an extensive range of high-performance rubber materials tailored for oil seal production, ensuring compatibility with diverse operating conditions. These materials are engineered to withstand a broad spectrum of chemicals and extreme temperature variations, both high and low.
[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 customizable non-standard oil seals, we employ premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, crafted to meet your unique requirements.

[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]
Our oil seals efficiently create an oil film through the precise contact between the lip and the shaft, achieving superior dynamic sealing with the aid of spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, which enhances the sealing effect; while stationary, it maintains contact to ensure a continued seal.

[Oil seal application fields]
Our oil seals are expertly crafted for use in engines, gearboxes, hydraulic pumps, reducers, and other high-demand equipment, particularly where high temperatures, high speeds, or corrosive environments are present. For challenging conditions where traditional seals fail, our PTFE oil seals provide longevity, lasting up to 20 times longer, and can effectively seal water, acid, gas, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to avoid tilting, and apply grease to the lip to mitigate dry grinding, ensuring optimal performance.
