Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in safeguarding your machinery. They expertly seal in grease, liquids, or protect against dirt, becoming indispensable in any rotating or moving assembly. These seals are vital to ensure a stable interspace between the stationary and moving components of mechanical equipment. An oil seal typically comprises three core elements:
A superior sealing material (the rubber component), robust metal casings, and resilient springs, culminating in a versatile sealing assembly that stands the test of time.
Explore our diverse range of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, each designed to cater to specific needs.
Our vast selection of high-quality rubber materials ensures that our oil seals meet the demands of various operating conditions. These materials are crafted to withstand a wide array of chemicals and endure extreme temperatures, from the scorching heat to the biting cold.
[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 bespoke solutions, we can craft non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your exact 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]
The brilliance of the oil seal lies in its ability to create a dynamic oil film through the strategic contact between the lip and the shaft. This is achieved by harnessing the pressure of a spring and the innate elasticity of the material. During rotation, the lip contracts due to frictional heat, enhancing the seal's effectiveness; when stationary, it ensures continuous contact to maintain the seal.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and beyond. They shine in high-temperature, high-speed, and corrosive environments, outperforming traditional rubber oil seals. For instance, PTFE oil seals offer an impressive lifespan, lasting up to 20 times longer and effectively sealing diverse media like water, acid, and gas.

[Oil seal selection and installation]
For optimal performance, consider the rotation speed, temperature, pressure, and characteristics of the medium. It's crucial to install the shaft vertically to prevent tilting and ensure the application of grease on the lip to minimize dry grinding.
