Product Description

Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in sealing grease, fluids, or dirt—crucial components within any rotating or moving assembly. They effectively bridge the gap between stationary and moving parts in mechanical equipment. Typically, an oil seal is crafted with three vital elements:
These include a sealing material (the rubber component), robust metal casings, and durable springs, creating a versatile sealing assembly.
Our extensive range features types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse needs.
Explore our broad selection of premium rubber materials tailored for the manufacturing of oil seals, ensuring they meet a variety of operational demands. These high-performance rubbers withstand a spectrum of chemicals and extreme temperatures, from scorching highs to 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 offer customizable non-standard oil seals, skillfully crafted from materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, to meet 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]
By forming an oil film through the precise contact between the lip and the shaft, the oil seal achieves dynamic sealing. It leverages the spring pressure and the elasticity of the material. Upon rotation, the lip contracts from frictional heat, enhancing the seal. When at rest, it maintains contact to ensure the seal remains intact.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, and reducers, excelling in high temperature, high-speed, and corrosive environments where traditional rubber oil seals may falter. Remarkably, PTFE oil seals can last up to 20 times longer than conventional counterparts, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
Consider the shaft's rotational speed, temperature, pressure, and medium characteristics comprehensively. Install the vertical shaft precisely to avoid tilting, and apply grease to the lip to minimize dry friction.
