Product Description

Oil seals, also known as rotary shaft seals, are indispensable in sealing applications for grease, liquids, or dirt. These critical components are essential for any rotating or moving assembly, providing stability between stationary and moving parts in mechanical equipment. Typically, an oil seal is composed of three fundamental elements:
A sealing material (rubber component), robust metal casings, and high-tension springs, forming a versatile and reliable sealing assembly.
Various types available include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide range of needs.
Our extensive selection of rubber materials for oil seals ensures they meet diverse operating conditions. These high-performance materials withstand a wide array of chemicals and extreme temperatures, whether soaring high or plummeting 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.

Customizable non-standard oil seals can be expertly crafted using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific 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 ingeniously creates an oil film through the precise contact between the lip and the shaft, achieving dynamic sealing enhanced by spring pressure and material elasticity. As rotation occurs, the lip contracts from frictional heat, strengthening the sealing effect; when stationary, it ensures sustained contact to maintain the seal.

[Oil seal application fields]
Our oil seals are widely employed in engines, gearboxes, hydraulic pumps, reducers, and other equipment, excelling in high-temperature, high-speed, and corrosive media applications, where traditional rubber oil seals have failed. For instance, PTFE oil seals offer longevity up to 20 times that of conventional oil seals and adeptly seal water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing an oil seal, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical shaft is correctly aligned to prevent tilting, and apply grease to the lip to minimize dry friction.
