Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in safeguarding machinery by effectively sealing against grease, liquids, or dirt. These indispensable components ensure that the gap between stationary and moving parts remains stable in any mechanical assembly, thus enhancing longevity and operational efficiency. Typically, an oil seal is ingeniously crafted from three primary elements:
A robust sealing material, typically a rubber component, fortified by sturdy metal casings and resilient springs, combines to form a versatile sealing assembly that reliably meets diverse needs.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring a perfect fit for every application.
Our offerings are crafted from an assortment of high-performance rubber materials, adept at withstanding a spectrum of chemicals and extreme temperature variations, ensuring adaptability to a plethora of operating conditions.
[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 bespoke needs, we offer customizable non-standard oil seals using specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[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]
The artful design of the oil seal ensures an effective oil film is created through the dynamic interaction between the lip and the shaft. This achieves superior dynamic sealing, leveraging spring pressure and material elasticity. As rotation occurs, the lip naturally contracts due to frictional heat, amplifying the sealing effect, while maintaining tight contact when stationary to uphold the seal.

[Oil seal application fields]
Our oil seals are indispensable across varied applications such as engines, gearboxes, hydraulic pumps, and reducers. They excel in demanding environments characterized by high temperatures, intense speeds, and corrosive media where traditional seals falter. Notably, PTFE oil seals deliver up to 20 times the lifespan of conventional options, adeptly sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
For optimal performance, consider the shaft's rotation speed, temperature, pressure, and media characteristics. Ensure vertical installation to prevent misalignment and apply grease to the lip to minimize friction and wear.
