Product Description

Product Description

 

Oil seals, often known as rotary shaft seals, play a crucial role in maintaining the integrity of mechanical systems by sealing grease, liquids, or preventing contaminants like dirt from entering the system. As indispensable components of any rotating and moving assembly, oil seals ensure stability and efficiency by effectively separating stationary and mobile parts. These seals typically comprise three essential elements:
A versatile sealing assembly composed of a sealing material (rubber component), metal casings, and springs, designed to meet various industrial needs.
Our range of oil seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse requirements.
We provide an extensive array of rubber materials meticulously selected for oil seal manufacturing to ensure optimal suitability across different operating conditions. These high-performance materials are engineered to withstand a wide spectrum of chemicals and extreme temperature variations, whether intensely high or low.
[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 from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to unique demands.

[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 a dynamic and effective seal by forming an oil film via contact between the lip and the shaft. This process is optimized through the combined effects of spring pressure and the elasticity of the material. During rotation, the lip's contraction due to frictional heat enhances the seal, while in a stationary state, it maintains a tight contact, ensuring the seal's integrity.

[Oil seal application fields]
Our oil seals are extensively employed in engines, gearboxes, hydraulic pumps, reducers, and other machinery, especially in high-temperature, high-speed, and corrosive environments where traditional rubber seals falter. Notably, PTFE oil seals offer remarkable durability, with a lifespan up to 20 times longer than conventional seals, and are capable of effectively sealing media such as water, acid, and gas.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and the characteristics of the medium. Ensure the vertical installation of the shaft to prevent tilting and apply grease to the lip, which minimizes dry friction and prolongs the seal's lifespan.
