Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding mechanical systems by effectively sealing grease, liquids, or dirt. Integral to any rotating or moving assembly, they ensure optimal stability between stationary and moving parts. An oil seal typically comprises three essential elements:
These include the sealing material (rubber component), durable metal casings, and robust springs. Together, they form a highly adaptable sealing assembly poised to meet diverse industrial needs.
Our extensive range of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering versatility for various applications.
We provide an array of specialized rubber materials for crafting oil seals, ensuring they can withstand a multitude of operating conditions. These advanced materials endure diverse chemicals and extreme temperatures, ensuring performance in both high and low thermal conditions.
[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 customizable non-standard oil seals, we utilize premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber to cater to 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 a precise oil film via the contact between its lip and the shaft. This is accomplished through spring pressure and the elasticity of the material. During rotation, the lip contracts due to frictional heat, enhancing the seal. When stationary, it retains contact to maintain an effective seal.

[Oil seal application fields]
These oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and similar equipment. They excel in high-temperature, high-speed, and corrosive environments where traditional seals may falter. Notably, PTFE oil seals offer longevity up to 20 times that of conventional counterparts, proficiently sealing water, acid, gas, and more.

[Oil seal selection and installation]
For optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics carefully. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry grinding.
