Product Description

An oil seal, commonly known as a rotary shaft seal, is indispensable in safeguarding mechanisms against the infiltration of grease, liquids, or dirt. Serving as the linchpin in any rotating or moving assembly, oil seals deftly stabilize the gap between stationary and dynamic components within mechanical systems. Typically, these seals are crafted from three core elements:
The seals are composed of a resilient sealing material (the rubber component), robust metal casings, and supportive springs, forming a remarkably versatile sealing assembly.
Our diverse range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others.
We proudly offer a comprehensive array of superior rubber materials for crafting oil seals, each meticulously chosen to ensure ideal performance across a variety of operating conditions. These exceptional materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperature fluctuations, whether exceedingly high or 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.

Our customizable, non-standard oil seals can be expertly crafted from premium materials including 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 oil seal ingenuity lies in forming an oil film via the interaction between the lip and shaft. This dynamic seal is achieved through a harmonious blend of spring tension and material elasticity. During rotation, frictional heat causes the lip to contract, intensifying the sealing capability, while at rest, it maintains a steadfast contact to sustain the seal.

[Oil seal application fields]
Our seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and other complex machinery. They excel particularly in demanding scenarios of high temperatures, rapid speeds, corrosive environments, and where traditional rubber seals falter. Notably, PTFE oil seals can outlast regular seals by an impressive factor of 20, reliably sealing water, acid, gas, and various other media.

[Oil seal selection and installation]
To ensure optimal performance, consider the rotation speed, temperature, pressure, and media characteristics of the shaft. Install the vertical shaft carefully to avert tilting and generously apply grease to the lip, minimizing dry grinding and promoting longevity.
