Product Description

Product Description

Oil seals, also known as rotary shaft seals, are pivotal in maintaining the integrity of mechanical systems by effectively sealing grease, liquids, and dirt. These indispensable components ensure the stable separation between stationary and moving parts within any rotating or moving assembly, safeguarding the system's performance. Typically crafted from three key elements:
A sealing material (rubber component), metal casings, and springs, these components come together to create a versatile sealing assembly that stands the test of various applications.
Diverse types available include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering solutions for a wide range of sealing needs.
We pride ourselves on providing a comprehensive selection of high-performance rubber materials for oil seal manufacturing. Our materials are engineered to endure a wide spectrum of chemicals and withstand extreme temperatures, ensuring optimal performance in any condition.
[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 specialized needs, our customizable non-standard oil seals can be manufactured using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, providing tailored solutions to your specific 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]
Through the ingenious design of lip and shaft interaction, the oil seal creates an effective oil film, achieving dynamic sealing with precision. As the shaft rotates, frictional heat enhances the seal by contracting the lip, while stationary contact preserves the seal's integrity, thanks to spring pressure and material elasticity.

[Oil seal application fields]
Our oil seals find versatile applications across engines, gearboxes, hydraulic pumps, reducers, and more. They excel in challenging conditions such as high temperatures, high speeds, and corrosive environments, where traditional seals may falter. PTFE oil seals, for instance, deliver up to 20 times the lifespan of conventional seals and effectively seal water, acid, gas, and other challenging media.

[Oil seal selection and installation]
For optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip, reducing dry friction and extending seal life.
