Product Description

Oil seals, also known as rotary shaft seals, are the unsung heroes of machinery, expertly sealing grease, liquids, or dirt to ensure smooth operation. These vital components stabilize the space between stationary and moving parts in mechanical equipment, offering reliability and efficiency. Typically, an oil seal consists of three fundamental elements:
The sealing assembly is a marvel of engineering, comprising a sealing material (rubber component), metal casings, and springs. This versatile design is the hallmark of durability and reliability.
Explore our extensive range of types including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
Our selection of high-performance rubber materials for oil seals is second to none, engineered to withstand a myriad of chemicals and extreme temperatures. They are meticulously crafted to perform under various operating conditions, whether facing the intensity of high heat or the chill of low temperatures.
[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.

For those unique needs, we offer customizable non-standard oil seals crafted from specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring bespoke solutions for your specific challenges.

[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 on a sophisticated principle, creating an oil film through the dynamic interaction between the lip and the shaft. Utilizing spring pressure and the inherent elasticity of the materials, it ensures a robust seal. During operation, frictional heat causes the lip to contract, enhancing the seal, while in rest mode, it maintains its grip to ensure integrity.

[Oil seal application fields]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, where traditional seals might fail. Take, for example, our PTFE oil seals, which offer longevity up to 20 times that of conventional seals, effectively sealing water, acids, gases, and beyond.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical installation to prevent tilting, and apply grease to the lip to mitigate dry grinding, thereby extending the longevity and efficiency of the seal.
