Product Description

Oil seals, also known as rotary shaft seals, are indispensable components of any rotating or dynamic assembly. These seals expertly manage the containment of grease, liquids, or dirt, ensuring the flawless stabilization of the space between stationary and moving parts within mechanical equipment. An oil seal is composed of three pivotal elements:
The assembly consists of a high-quality sealing material (rubber component), durable metal casings, and dependable springs, providing an adaptable sealing solution for various applications.
Our offerings include a variety of types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, designed to meet diverse and specific sealing requirements.
Discover our wide range of superior rubber materials, specifically designed for the manufacture of high-performance oil seals. These materials are crafted to resist a wide spectrum of chemicals and endure extreme high and low temperatures.
[Introducing 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 excel in the creation of tailor-made non-standard oil seals, utilizing premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber to ensure optimal performance.

[Oil Seal Core Structure Types]

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 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 Its Sealing Principle]
The oil seal forms an oil film through the precise interaction between its lip and the shaft. This dynamic sealing process benefits from both the spring pressure and the material's elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal's effectiveness; while at rest, it maintains contact to preserve the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals are broadly applied in engines, gearboxes, hydraulic pumps, reducers, and more. They perform exceptionally in high-temperature, high-speed, and corrosive environments, surpassing traditional rubber oil seals. Notably, PTFE seals extend lifespan by up to 20 times, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
Consider the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to reduce dry grinding and enhance longevity.
