Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in safeguarding grease, liquids, and protecting against dirt. They are indispensable components in any rotating or moving assembly, expertly stabilizing the gap between stationary and mobile parts within mechanical systems. Typically, an oil seal comprises three essential elements that ensure its effectiveness:
The assembly consists of a meticulously engineered sealing material (rubber component), robust metal casings, and resilient springs, forming a highly adaptable sealing solution.
Various types of oil seals include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering a wide selection for diverse needs.
Our extensive range of rubber materials for oil seal manufacturing guarantees compatibility with various operating conditions. These exceptional materials withstand a spectrum of chemicals and extreme temperatures, whether high or low, ensuring unmatched performance.
[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 offer customization for non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your 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 achieves dynamic sealing by forming an oil film through lip and shaft contact. This dynamic seal, enhanced by spring pressure and material elasticity, adapts to rotation by contracting under frictional heat, improving seal effectiveness, and maintains contact when stationary to ensure continued sealing.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, especially in demanding environments with high temperatures, velocities, and corrosive media. PTFE oil seals significantly outperform traditional variants, offering a lifespan up to 20 times longer, and proficiently sealing water, acid, gas, and other challenging media.

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