Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in safeguarding components by sealing in grease, liquids, or dirt. As an indispensable element of any mechanical assembly, the oil seal ensures seamless operation by maintaining the crucial separation between stationary and moving components. Typically, these seals are composed of three essential elements:
A sealing material (rubber component), metal casings, and springs unite to form a highly adaptable sealing assembly, designed to meet varied requirements with precision.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, alongside numerous other innovative variants.
We provide an extensive array of rubber materials to manufacture oil seals, tailoring them to diverse operational contexts. These advanced rubber materials are engineered to withstand a broad spectrum of chemicals and temperatures ranging from extreme heat to severe cold, ensuring optimal performance.
[Comprehensive 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.

For non-standard oil seals, we offer customization with an array of superior materials including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring a perfect fit for specific needs.

[Core Structure 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)

[Critical Structural Components 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

[Principles of Oil Sealing and Mechanisms]
The ingenious design of the oil seal ensures a flawless oil film, created by the precise contact between the lip and shaft. This dynamic sealing exploits the synergy of spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal, while at rest, the lip maintains contact to preserve the integrity of the seal.

[Versatile Applications of Oil Seals]
Oil seals find extensive applications in engines, gearboxes, hydraulic pumps, and reducers. They excel in high-temperature, high-speed, or corrosive environments where traditional seals falter. Remarkably, PTFE oil seals can outlast standard seals by up to 20 times, efficiently sealing water, acid, gas, and diverse media.

[Guidelines for Oil Seal Selection and Installation]
When selecting an oil seal, consider the shaft's rotational speed, temperature, pressure, and the medium's characteristics. Ensure vertical installation to prevent misalignment and apply grease to the lip to minimize dry friction, thereby extending the seal's lifespan.
