Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in preventing the ingress of grease, liquids, or dirt into mechanical systems. These indispensable components are integral to any assembly involving rotating or moving parts, efficiently stabilizing the interface between stationary and dynamic elements. An oil seal typically encompasses three essential elements:
A sealing material made of rubber, robust metal casings, and resilient springs. This versatile sealing assembly is designed to meet various mechanical needs.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, to name just a few.
We proudly offer a broad spectrum of rubber materials tailored for crafting oil seals, ensuring they are perfectly suited for diverse operational demands. These high-performance rubbers are engineered to withstand a vast array of chemicals and endure extreme temperatures, whether soaring high or plunging low.
[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 can customize non-standard oil seals using cutting-edge materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to your 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]
The oil seal's ingenuity lies in forming a protective oil film through the interaction of its lip and shaft. Employing spring pressure and material elasticity, it achieves dynamic sealing. As the shaft rotates, frictional heat causes the lip to contract, intensifying the seal; it maintains contact even when stationary, ensuring a continuous seal.

[Oil seal application fields]
Our oil seals find widespread application in engines, gearboxes, hydraulic pumps, reducers, and other machinery, particularly in demanding conditions like high temperatures, elevated speeds, corrosive media, or environments where conventional rubber oil seals fall short. For instance, PTFE oil seals surpass traditional ones by up to 20-fold in longevity, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing an oil seal, consider the shaft's rotation speed, thermal conditions, pressure levels, and the nature of the medium. Ensure the vertical shaft is installed correctly to avoid tilt, and apply grease to the lip to minimize the risk of dry grinding.
