Product Description

Oil seals, known in the industry as rotary shaft seals, are indispensable for maintaining the integrity of machinery by effectively sealing grease, liquids, and dirt. They play a crucial role in any rotating or moving assembly, ensuring stability by bridging the gap between stationary and dynamic components in mechanical systems. An oil seal typically comprises three key elements:
These elements include a sealing material (rubber component), robust metal casings, and durable springs, forming a versatile sealing assembly that meets diverse industrial needs.
Our extensive range of oil seal types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to various application requirements.
We provide an expansive variety of specialized rubber materials designed to manufacture oil seals tailored to diverse operating conditions. Our high-performance rubber materials are engineered to withstand a wide array of chemicals and endure extreme temperatures, guaranteeing optimal performance regardless of the environmental challenges.
[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 seeking tailored solutions, we offer customizable non-standard oil seals crafted from high-quality materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring exceptional performance in demanding applications.

[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 expertly creates an oil film by utilizing the precise contact between the lip and the shaft, achieving dynamic sealing through the combined forces of spring pressure and the intrinsic elasticity of the material. Upon rotation, the lip contracts due to frictional heat, enhancing the seal; when stationary, it maintains a steadfast contact, ensuring continuous sealing integrity.

[Oil seal application fields]
Our oil seals are extensively employed in engines, gearboxes, hydraulic pumps, reducers, and various high-performance equipment. They excel in environments characterized by high temperatures, high speeds, and corrosive media, where conventional oil seals may falter. Notably, our advanced PTFE oil seals can outlast traditional counterparts by up to 20 times, effectively sealing water, acid, gas, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the rotational speed, temperature, pressure, and medium characteristics. Ensure vertical installation to prevent tilting and apply grease to the lip to minimize dry grinding, thereby enhancing longevity and performance.
