Product Description

Oil seals, often recognized as rotary shaft seals, are pivotal in preventing the ingress of grease, liquids, or dirt. They serve as indispensable components in any rotating or moving assembly, ensuring stability between stationary and dynamic parts in mechanical setups. Typically, an oil seal comprises three core components:
These include a sealing material, primarily a rubber component known for its flexibility, metal casings for structural support, and springs to maintain constant pressure, culminating in a versatile sealing assembly.
Our range features a variety of types, such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many others, each tailored to specific requirements.
We proudly offer a vast selection of premium rubber materials for crafting oil seals, meticulously chosen to withstand diverse operational challenges. These advanced materials excel in resisting a wide spectrum of chemicals and can endure both extreme heat and 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.

Our customizable, non-standard oil seals are crafted using high-grade materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, providing tailored solutions 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 oil seal expertly forms a protective oil film through the intimate contact between its lip and the shaft, utilizing the synergy of spring pressure and material elasticity to achieve dynamic sealing. As it rotates, frictional heat causes the lip to contract, enhancing the seal; when stationary, it maintains contact to secure the seal.

[Oil Seal Application Fields]
Our oil seals are indispensable in critical components like engines, gearboxes, hydraulic pumps, and reducers. They excel in high-temperature, high-speed, and corrosive environments where traditional seals falter. PTFE oil seals offer exceptional longevity, up to 20 times longer than standard seals, adeptly handling water, acid, gas, and other challenging media.

[Oil Seal Selection and Installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium properties. Ensure the vertical shaft is correctly installed to prevent tilting, and apply grease to the lip to minimize dry friction.
