Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding the integrity of mechanical assemblies. These indispensable components prevent grease, liquids, or dirt from compromising the delicate interplay between stationary and moving parts in machinery. At the heart of an oil seal's design lie three essential elements:
The artful combination of a sealing material (typically a robust rubber component), durable metal casings, and precision-engineered springs culminates in a versatile sealing assembly.
Our extensive portfolio features an array of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, tailored to meet diverse application needs.
Discover our expansive selection of premium rubber materials, meticulously curated for oil seal manufacturing to ensure compatibility across a spectrum of operating conditions. These cutting-edge materials are engineered to withstand a variety of chemicals and endure extreme temperature fluctuations, ensuring performance even in the harshest climates.
[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 specialize in crafting customizable non-standard oil seals utilizing an array of advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your specific requirements.

[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 innovative design of our oil seals creates a superior oil film through precise contact between the lip and the shaft. Leveraging spring pressure and material elasticity, they achieve dynamic sealing. When in motion, the lip cleverly contracts due to frictional heat, intensifying the seal's effectiveness. At rest, it maintains a consistent contact to ensure a reliable seal.

[Oil seal application fields]
Our oil seals find extensive use across a myriad of applications, including engines, gearboxes, hydraulic pumps, reducers, and more. They excel in demanding environments characterized by high temperatures, high speeds, corrosive media, or where traditional rubber oil seals falter. Notably, PTFE oil seals offer up to 20 times the longevity of conventional counterparts and effectively seal water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, it is crucial to consider the shaft's rotational speed, temperature, pressure, and the nature of the medium. Ensure the vertical shaft is installed to prevent tilting, and apply a generous layer of grease to the lip for reduced dry grinding, enhancing durability and performance.
