Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in ensuring the seamless operation of machinery by effectively sealing grease, liquids, and dirt. As a fundamental component of any rotating and moving assembly, the oil seal harmonizes the space between stationary and moving parts, optimizing the functionality and longevity of mechanical equipment. Typically, an oil seal is composed of three indispensable elements:
A sealing material, specifically the rubber component, alongside robust metal casings and springs, combine to form a versatile sealing assembly admired for its adaptability and high-performance standards.
Our range covers a diverse array of types including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, ensuring a perfect match for every application.
Our diverse selection of rubber materials is meticulously chosen to manufacture oil seals that meet the unique demands of various operating conditions. These high-performance rubber materials are engineered to withstand an extensive range of chemicals and endure both extremely high and low temperatures, guaranteeing unmatched durability and reliability.
[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 those requiring customized solutions, we offer non-standard oil seals crafted from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring tailored performance for any application.

[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 ingenious design of the oil seal creates a protective oil film through the interaction between the lip and the shaft, achieving dynamic sealing through the synergistic effect of spring pressure and material elasticity. During rotation, the lip's contraction due to frictional heat enhances the sealing efficacy; when stationary, it remains in contact to ensure the seal's integrity.

[Oil seal application fields]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and a wide range of equipment, excelling in high temperature and high-speed scenarios, as well as in corrosive media where traditional seals falter. Notably, PTFE oil seals provide up to 20 times the lifespan of conventional seals, adeptly sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, take into account the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical shaft is correctly installed to avoid tilting and apply grease to the lip to minimize dry friction, thereby extending the oil seal's life.
