Product Description

Product Description

Oil seals, also known as rotary shaft seals, are vital components in the realm of mechanical engineering. These seals are indispensable for securing grease, liquids, or dirt, ensuring a flawless operation. As an integral part of any rotating or moving assembly, oil seals fortify the connection between stationary and dynamic elements, preserving the harmony of mechanical systems. A typical oil seal is composed of three primary elements:
A sealing material (rubber component), metal casings, and springs, creating a versatile and reliable sealing assembly that stands the test of time.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, providing numerous options to meet diverse requirements.
We proudly offer an expansive selection of premium rubber materials tailored for oil seal manufacturing, ensuring each seal meets the demands of varying operational environments. These robust materials are engineered to withstand harsh chemicals and fluctuating temperatures, from scorching highs to biting lows.
[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.

Our non-standard oil seals can be customized with an array of materials including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, to meet your specific needs.

[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]
Harnessing the power of precision, the oil seal forms an oil film via the contact between its lip and the shaft, delivering dynamic sealing through the synergy of spring tension and material elasticity. During rotation, the lip contracts under frictional heat, enhancing the seal; when at rest, it maintains contact to ensure continued sealing integrity.

[Oil seal application fields]
Our oil seals are deployed in a wide spectrum of machinery, from engines and gearboxes to hydraulic pumps and reducers. They excel in challenging conditions, including high temperatures, rapid speeds, corrosive environments, and where traditional seals fall short. Notably, PTFE oil seals can outperform traditional options by up to 20 times, effectively sealing water, acid, gas, and more.

[Oil seal selection and installation]
For optimal performance, consider shaft rotation speed, temperature, pressure, and medium characteristics. Ensure correct installation by placing the shaft vertically to prevent misalignment, and apply grease to the lip to mitigate dry friction.
