Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding the integrity of mechanical assemblies. They are instrumental in effectively sealing grease, liquids, or contaminants. Serving as a critical component, oil seals ensure seamless operation by maintaining equilibrium between stationary and dynamic parts within mechanical equipment. Typically, each oil seal is composed of three vital elements:
A robust sealing material (rubber component), durable metal casings, and precision-engineered springs. This versatile assembly exemplifies exceptional sealing capabilities.
Our product range includes a variety of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
We proudly offer an extensive array of rubber materials crafted for the manufacturing of high-quality oil seals, ensuring their adaptability to diverse operating environments. These superior rubber materials are engineered to withstand a broad spectrum of chemicals and extreme temperatures, ensuring reliability in both high and low-temperature conditions.

[Oil seal material introduction]

Our expertise extends to producing customizable non-standard oil seals using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet your specific needs.

[Oil seal and sealing principle]

The precision-engineered oil seal forms a critical oil film through the strategic contact between the lip and the shaft, achieving dynamic sealing excellence. Utilizing the synergy of spring pressure and material elasticity, it adapts seamlessly to both rotary and stationary states. When in rotation, the lip's contraction due to frictional heat enhances the sealing efficiency, while in stationary phases, it ensures a steadfast seal.

[Oil seal application fields]

Our oil seals find extensive applications across engines, gearboxes, hydraulic pumps, and reducers, excelling in high-temperature, high-speed, and corrosive media environments where traditional rubber oil seals fall short. PTFE oil seals, in particular, offer remarkable durability, lasting up to 20 times longer than conventional options, and deliver robust sealing for water, acids, gases, and other challenging media.

[Oil seal selection and installation]

It is essential to consider the shaft's rotational speed, temperature, pressure, and medium characteristics holistically. Ensure precise installation by positioning the shaft vertically to prevent tilting, and apply grease to the lip to minimize friction and enhance longevity.

[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.

[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
