Product Description

Oil seals, also known as rotary shaft seals, are indispensable in sealing grease, liquids, and dirt, making them a key element in any rotating or moving assembly. These seals are vital for maintaining stability between stationary and moving components in mechanical equipment. Generally, an oil seal is comprised of three essential elements:
A sealing material (rubber component), robust metal casings, and resilient springs. This combination forms a versatile and efficient sealing assembly.
Our oil seal types include a variety of models such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the versatile TC4, among others.
We proudly offer an extensive range of premium rubber materials for creating oil seals, ensuring they meet diverse operational demands. These high-performance materials withstand numerous chemicals and extreme temperatures, whether soaring highs or frigid lows.
[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 provide fully customizable non-standard oil seals crafted from materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, adapted to your specific 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 between the lip and shaft, achieving dynamic sealing through the synergy of spring pressure and material elasticity. As rotation occurs, the lip contracts from frictional heat, bolstering the seal; when motion ceases, it maintains contact to ensure continuous sealing.

[Oil seal application fields]
Our oil seals are extensively used in engines, gearboxes, hydraulic pumps, reducers, and more, especially under high temperature, high-speed, corrosive media conditions, or when traditional seals fall short. For example, PTFE oil seals can outlast conventional seals by up to 20 times, effectively sealing water, acid, gas, and other media.

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