Product Description

Oil seals, often referred to as rotary shaft seals, play a crucial, yet often overlooked role in machinery. These components are masterfully designed to seal grease, liquids, or dirt, ensuring the seamless operation of equipment. They stabilize the space between stationary and moving parts within mechanical systems, providing the reliability and efficiency necessary for optimal performance. An oil seal typically comprises three essential elements that work harmoniously together:
The sealing assembly is an engineering wonder, featuring a sophisticated combination of sealing materials (rubber components), metal casings, and springs. This flexible and robust design stands as a testament to unparalleled durability and dependability.
Discover our extensive array of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the cutting-edge TC4, among many others.
Our high-performance rubber materials for oil seals are unmatched, specifically crafted to resist a broad spectrum of chemicals and endure extreme temperatures. Each material is meticulously engineered to perform reliably under varying conditions, whether confronting intense heat or enduring the 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.

For those with unique requirements, we provide customizable non-standard oil seals made from specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber. These bespoke solutions are crafted to meet your specific challenges and applications.

[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 functions on an intricate principle, forming an oil film through the dynamic interaction between the lip and the shaft. By employing spring pressure combined with the natural elasticity of materials, it delivers a robust seal. During operation, the heat generated by friction causes the lip to contract, enhancing the seal, while in rest mode, it maintains its grip to ensure continued integrity.

[Oil seal application fields]
Our oil seals are essential in engines, gearboxes, hydraulic pumps, reducers, and more. They thrive in high-temperature, high-speed, and corrosive environments where standard seals might falter. Take, for example, our PTFE oil seals, which provide longevity up to 20 times longer than traditional seals, effectively sealing not only water, acids, and gases but beyond.

[Oil seal selection and installation]
When choosing and installing oil seals, consider the rotation speed of the shaft, alongside temperature, pressure, and medium characteristics. Ensure vertical installation to avoid tilting, and apply grease to the lip to reduce dry grinding, thus extending the seal's lifespan and maintaining its efficiency.
