Product Description

Oil seals, also known as rotary shaft seals, play a vital role in safeguarding your machinery's integrity! They are indispensable in sealing grease, liquids, or dirt, ensuring your equipment operates smoothly. These crucial components are integral to any rotating assembly, maintaining the delicate balance between stationary and moving parts in mechanical systems. Typically, an oil seal is crafted from three primary components:
A sealing material (rubber component), metal casings, and springs. This versatile sealing assembly is engineered to provide optimal performance and reliability.
Our extensive range of types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, amongst others, catering to diverse industrial needs.
We proudly offer a broad spectrum of high-quality rubber materials for manufacturing our oil seals, tailored to withstand various operating conditions. These superior rubber compounds are designed to resist a wide array of chemicals and withstand extreme temperatures, whether scorching hot or icy cold, ensuring longevity and durability.
[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 crafted from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering robust performance tailored 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 ingeniously forms an oil film through the dynamic contact between the lip and the shaft, achieving reliable dynamic sealing with spring tension and material elasticity. During operation, frictional heat causes the lip to contract, enhancing the seal, while in a stationary state, the lip maintains contact to ensure a secure seal.

[Oil seal application fields]
Our advanced oil seals are extensively employed in engines, gearboxes, hydraulic pumps, reducers, and more, particularly in high-temperature, high-speed, and corrosive environments where traditional seals falter. For example, our PTFE oil seals offer longevity up to 20 times greater than conventional oil seals and can effectively seal water, acid, gas, and a range of other challenging media.

[Oil seal selection and installation]
A comprehensive analysis of the shaft's rotation speed, temperature, pressure, and medium characteristics is crucial. Ensure the vertical shaft is correctly installed to prevent tilting, and apply grease to the lip to minimize dry grinding, ensuring optimal performance.
