Product Description

Oil seals, often referred to as rotary shaft seals, play a crucial yet understated role in machinery. They effectively seal out grease, liquids, or dirt, ensuring the seamless operation of equipment. These indispensable components act as a bridge between stationary and moving parts, providing unwavering reliability and efficiency. The architecture of a typical oil seal is ingeniously simple, comprising three essential elements:
The sealing assembly is a testament to engineering brilliance, featuring a composite of sealing materials (including a resilient rubber component), robust metal casings, and supportive springs. This multifaceted design underpins its durability and trustworthiness, making it a reliable choice.
Delve into our vast selection of oil seal types, including the classic TC, TG, TA, SA, SB, SC, DC, MC, MG, and the advanced TCV, TCN, along with the groundbreaking TC4, and more.
Our unparalleled collection of high-performance rubber materials for oil seals is designed to withstand a diverse range of chemicals and extreme thermal conditions. These materials are engineered with precision to thrive in various operating environments, whether enduring the searing heat or the biting 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 specialized requirements, we present customizable non-standard oil seals made from bespoke materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring tailored solutions to meet your specific challenges with precision.

[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 operates on an intricate principle, forming an oil film through the vibrant interaction between the lip and shaft. By employing spring tension and the natural elasticity of materials, it creates a secure seal. During operation, the frictional heat causes the lip to contract, strengthening the seal, while at rest, it maintains its grip for continued integrity.

[Oil seal application fields]
Our expertly crafted oil seals are crucial in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, where traditional seals often falter. Our PTFE oil seals, for example, boast a lifespan up to 20 times longer than conventional seals, providing robust sealing against water, acids, gases, and beyond.

[Oil seal selection and installation]
When selecting and installing oil seals, it's vital to consider the shaft's rotational speed, ambient temperature, pressure, and the characteristics of the medium. Ensure vertical installation to avoid tilting, and apply a layer of grease to the lip to prevent dry grinding, effectively extending the seal's lifespan and efficiency.
