Product Description

Oil seals, often called rotary shaft seals, play a pivotal role in safeguarding machinery. These essential components are designed to prevent the ingress of grease, liquids, or dirt, thus ensuring the longevity and efficiency of any rotating or moving assembly. By effectively stabilizing the gap between stationary and dynamic parts, oil seals are indispensable in mechanical equipment. Typically, these seals are composed of three vital elements:
First, the sealing material, usually rubber, offers flexibility and resilience. This is complemented by robust metal casings that provide structural integrity. Lastly, springs are integrated to maintain the necessary pressure, making it a multifunctional sealing assembly.
Our offerings include a wide array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
We present an extensive array of premium rubber materials for crafting oil seals, each selected to meet specific operational demands. These materials excel in resisting a spectrum of chemicals and function admirably across a broad temperature range, from scorching highs to frigid lows, ensuring durability and reliability.
[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.

We provide bespoke, non-standard oil seals produced from cutting-edge materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet your unique application 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]
The oil seal forms a protective oil film via the interaction of the lip and shaft. This dynamic sealing is accomplished through the precise balance of spring tension and material flexibility. During rotation, frictional heat causes the lip to contract, enhancing the seal, while at rest, contact is maintained to ensure consistent sealing performance.

[Oil seal application fields]
Our oil seals excel in an array of applications including engines, gearboxes, hydraulic pumps, and reducers. They thrive in challenging environments characterized by high temperatures, rapid speeds, and corrosive materials, where traditional seals might falter. Notably, PTFE oil seals offer longevity—lasting up to 20 times longer than conventional seals—while effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, it's crucial to consider the shaft's rotation speed, temperature, pressure, and medium properties. Ensure the shaft is vertical to prevent misalignment, and apply grease to the lip to minimize friction and enhance performance.
