Product Description

Oil seals, also referred to as rotary shaft seals, are an essential component in machinery, providing an unparalleled barrier against grease, liquids, and dirt. As the backbone of rotating and moving assemblies, oil seals maintain the harmony between stationary and dynamic mechanical parts. These vital seals are constructed from three pivotal components:
The assembly boasts a sealing material made from premium-grade rubber, robust metal casings, and resilient springs. This combination results in a versatile and formidable sealing solution that stands the test of time.
Our diverse range of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, each meticulously designed to meet varied industry specifications and requirements.
We offer an extensive selection of rubber materials for oil seal manufacturing, each engineered to fulfill a spectrum of operational needs. Our high-performance rubbers exhibit exceptional resistance to a wide array of chemicals and can withstand extreme temperatures, whether blistering hot or freezing cold.
[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 clients in need of custom, non-standard oil seals, we provide specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, all tailored to meet specific performance criteria and 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]
Oil seals function by creating a protective oil film through the interaction between the lip and shaft. The dynamic sealing is achieved with the support of spring pressure and the material's inherent elasticity. As rotation occurs, frictional heat causes the lip to contract, thus enhancing the seal; when stationary, it maintains a secure and tight seal.

[Oil seal application fields]
Our oil seals excel in various applications, from engines and gearboxes to hydraulic pumps and reducers. They are particularly effective in high-temperature, high-speed, or corrosive environments where traditional seals falter. Remarkably, PTFE oil seals offer up to 20 times the lifespan of conventional options, providing robust sealing against water, acids, gases, and other challenging substances.

[Oil seal selection and installation]
Selecting the right oil seal involves assessing shaft rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to minimize dry friction, ensuring longevity and performance.
