Product Description

Oil seals, also known as rotary shaft seals, play an indispensable role in mechanical assemblies. These crucial components are designed to effectively seal grease, liquids, and dirt, ensuring the seamless operation of rotating and moving assemblies. By maintaining the delicate balance between stationary and dynamic elements, oil seals stabilize mechanical equipment. Typically, an oil seal is composed of three vital components:
The sealing material (rubber component), robust metal casings, and high-tension springs. These elements combine to create a highly adaptable sealing assembly.
Our extensive range includes various types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the versatile TC4, among others.
We take pride in offering an extensive selection of premium rubber materials specifically engineered for oil seal production. Our materials are meticulously chosen to withstand a broad spectrum of operating conditions, including exposure to diverse chemicals and extreme temperature variations, be it scorching highs or freezing lows.
[Introduction to Oil Seal Materials]

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 capabilities allow for the production of bespoke, non-standard oil seals crafted from advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet your unique specifications.

[Core Structural Types of Oil Seals]

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)

[Principal Structural Elements of Oil Seals]

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

[Principle of Oil Sealing]
Our oil seals ingeniously form an oil film through the interaction between the lip and the shaft. This dynamic sealing is achieved by leveraging the pressure from a spring and the inherent elasticity of the material. As the system rotates, frictional heat causes the lip to contract, thereby enhancing the sealing efficacy; when stationary, the lip maintains a firm contact, ensuring the seal's integrity.

[Applications of Oil Seals]
Our oil seals are indispensable in applications ranging from engines, gearboxes, hydraulic pumps, to reducers, especially under challenging conditions involving high temperatures, rapid speeds, or corrosive environments where traditional seals falter. Remarkably, PTFE oil seals can outlast standard oil seals by up to 20 times, sealing a variety of media such as water, acids, gases, and more.

[Criteria for Oil Seal Selection and Installation]
When selecting and installing an oil seal, consider the rotational speed, temperature, pressure, and medium characteristics of the shaft. Ensure that the shaft is installed vertically to prevent tilting and apply grease to the lip to minimize dry grinding for optimal performance.
