Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in sealing grease, liquids, or dirt. These indispensable components are vital to any rotating or moving assembly, stabilizing the space between the stationary and moving parts within mechanical equipment. An oil seal is elegantly constructed from three primary components:
A versatile sealing assembly comprising a sealing material (often a high-quality rubber component), metal casings, and springs. This combination ensures reliability across various applications.
Our selection includes multiple types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, catering to diverse needs.
We present a wide array of premium rubber materials for manufacturing oil seals, carefully designed for various operational conditions. These high-performance materials excel in withstanding a spectrum of chemicals and extreme temperatures, whether soaring highs or chilling 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.

We can tailor-make non-standard oil seals using specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering bespoke solutions for unique requirements.

[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)

[Essential 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

[Understanding Oil Seal and Sealing Principles]
The oil seal ingeniously forms an oil film through the contact between the lip and the shaft, achieving effective dynamic sealing by utilizing spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, amplifying the sealing efficacy; while stationary, it sustains contact to preserve the integrity of the seal.

[Application Fields of Oil Seals]
Our oil seals find widespread use in engines, gearboxes, hydraulic pumps, reducers, and other equipment, especially in high-temperature, high-speed, or corrosive environments, where traditional rubber oil seals fall short. For example, PTFE oil seals boast a lifespan up to 20 times longer than conventional ones and can seamlessly seal water, acid, gas, and more.

[Selecting and Installing Oil Seals]
Consider key factors like rotation speed, temperature, pressure, and the medium's characteristics for optimal performance. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry grinding and extend the seal's longevity.
