Product Description

Oil seals, also known as rotary shaft seals, are indispensable for sealing grease, liquids, or dirt. They play a crucial role in any rotating and moving assembly by ensuring a stable barrier between stationary and moving parts in mechanical equipment. Fundamentally, an oil seal is crafted with three essential components:
The assembly comprises a robust sealing material (rubber component), resilient metal casings, and dependable springs, making it a versatile and reliable sealing solution.
Available types include TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, each designed to meet specific requirements.
We provide a vast array of rubber materials tailored for oil seal production, ensuring they meet diverse operational demands. These cutting-edge rubber materials withstand an extensive range of chemicals and extreme temperatures, whether scorching 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 can be crafted using premium materials such as fluorine rubber, silicone rubber, refined rubber, and propylene rubber, catering to unique needs.

[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 operates by forming an oil film through the dynamic interaction between the lip and the shaft. It achieves a secure dynamic seal using spring pressure and the innate elasticity of materials. During rotation, frictional heat causes the lip to contract, amplifying the sealing effect, while when stationary, it maintains a tight grip to ensure the seal remains intact.

[Oil seal application fields]
These seals are extensively used in engines, gearboxes, hydraulic pumps, reducers, and more, especially under conditions of high temperatures, high speeds, and corrosive media. In scenarios where traditional rubber oil seals fall short, PTFE oil seals excel, lasting up to 20 times longer and effectively sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting oil seals, consider the shaft’s rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilt and apply grease to the lip to minimize dry friction, maximizing performance and longevity.
