Product Description

Oil seals, also known as rotary shaft seals, serve a crucial role in sealing grease, liquids, and dirt. As an indispensable component in rotating and moving assemblies, oil seals ensure the stability between stationary and dynamic parts of mechanical equipment. These seals typically consist of three core elements:
A sealing material crafted from superior rubber, durable metal casings, and resilient springs. This assembly offers a versatile and robust sealing solution.
The range of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, catering to diverse requirements.
We provide a comprehensive array of rubber materials for oil seal manufacturing, designed to meet various operational demands. Our high-performance rubbers resist a wide spectrum of chemicals and endure extreme temperatures, whether scorching or freezing.
[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 those seeking customizable, non-standard oil seals, we offer materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to 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]
Oil seals create a protective oil film through the interaction between the lip and shaft. Dynamic sealing is achieved with the aid of spring pressure and the material's inherent elasticity. During rotation, friction-induced heat causes the lip to contract, enhancing the seal; when still, it maintains a tight seal.

[Oil seal application fields]
Our oil seals serve diverse applications, such as engines, gearboxes, hydraulic pumps, and reducers, especially in high-temperature, high-speed, or corrosive environments where traditional seals fail. Notably, PTFE oil seals last up to 20 times longer than regular ones, effectively sealing water, acids, gases, and other demanding media.

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