Product Description

Oil seals, also known as rotary shaft seals, are indispensable in ensuring the seamless operation of machinery by effectively sealing grease, liquids, or dirt. These vital components play a crucial role in any rotating or moving assembly, creating a stable boundary between stationary and dynamic parts in mechanical equipment. Typically, an oil seal comprises three core elements:
A robust sealing material (typically a rubber component), complemented by durable metal casings and resilient springs, together form a versatile and reliable sealing assembly.
Available variants include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse sealing needs.
Our extensive selection of high-quality rubber materials for manufacturing oil seals ensures adaptability to various demanding operating conditions. These superior rubber compounds can withstand exposure to a wide spectrum of chemicals and extreme temperature variations, ensuring durability and performance.
[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 the flexibility of producing customizable non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet 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 advanced design of the oil seal forms an efficient oil film through the precise contact between the lip and the shaft. This achieves dynamic sealing by exploiting spring tension and material elasticity. During rotation, the lip's frictional heat induces contraction, enhancing the seal; while at rest, it maintains contact to ensure seal integrity.

[Oil seal application fields]
Our oil seals find extensive application across engines, gearboxes, hydraulic pumps, reducers, and more, especially under extreme conditions with high temperatures, high speeds, or corrosive environments where conventional rubber oil seals fall short. For instance, our PTFE oil seals offer remarkable longevity, lasting up to 20 times longer than standard seals, and can effectively seal water, acid, gas, among other media.

[Oil seal selection and installation]
When selecting and installing oil seals, it's vital to consider factors like rotation speed, temperature, pressure, and the characteristics of the medium. Ensuring vertical shaft installation helps prevent tilting, while applying grease to the lip reduces wear from dry friction, optimizing performance.
