Product Description

Oil seals, often known as rotary shaft seals, are indispensable guardians of your machinery, adeptly sealing grease, liquids, or dirt. They play a crucial role in any rotating or moving assembly, expertly stabilizing the gap between stationary and moving components within mechanical equipment. Typically, an oil seal is crafted from three essential elements:
These elements include a robust sealing material (rubber component), durable metal casings, and resilient springs, combining to form a highly versatile sealing assembly tailored for diverse applications.
Our range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring we meet every sealing need with precision.
We provide a comprehensive array of premium rubber materials for crafting oil seals, ensuring they are perfectly suited to a wide array of operating conditions. These high-performance materials are engineered to withstand a broad spectrum of chemicals and extreme temperatures, whether soaring or freezing.
[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.

Our customizable non-standard oil seals are crafted using specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering tailored solutions for unique specifications.

[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 forms an oil film through the contact between the lip and the shaft, achieving dynamic sealing by leveraging spring pressure and the inherent elasticity of the material. During rotation, the lip contracts due to frictional heat, significantly enhancing the sealing effect; while stationary, it maintains contact to ensure the integrity of the seal.

[Oil seal application fields]
Our oil seals are extensively used in engines, gearboxes, hydraulic pumps, reducers, and more, particularly in high-temperature, high-speed, or corrosive environments where traditional rubber oil seals fall short. For example, PTFE oil seals offer longevity up to 20 times that of conventional seals, adeptly sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
For optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics comprehensively. It's crucial to install vertical shafts to prevent tilting and to apply grease to the lip to minimize dry grinding, ensuring smooth operation.
