Product Description

Product Description

Oil seals, also known as rotary shaft seals, are indispensable in the world of mechanical assemblies. These seals are meticulously designed to prevent the leakage of grease, liquids, or dirt, ensuring the seamless operation of any rotating and moving equipment. The oil seal plays a critical role by stabilizing the space between stationary and active components. Each seal is ingeniously crafted from three essential elements:
The oil seal assembly is a marvel of engineering, composed of a sealing material (rubber component), robust metal casings, and tension springs. This versatile assembly is adaptable to suit a myriad of applications.
Our extensive range of oil seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, each designed to meet specific sealing needs.
Our collection of oil seals offers a diverse selection of high-performance rubber materials. These expertly crafted materials are designed to withstand a wide variety of chemicals and extreme temperature conditions, be it scorching heat or frigid cold, ensuring durability and reliability.
[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 in need of bespoke solutions, we provide customizable non-standard oil seals using premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[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 a fascinating principle: it forms an effective oil film through the interaction of the lip and shaft, achieving dynamic sealing. The spring's pressure combined with the material's innate elasticity ensures an optimal seal. During rotation, frictional heat causes the lip to contract, enhancing the seal, while in a stationary state, the lip maintains its grip to preserve the integrity of the seal.

[Oil seal application fields]
Our oil seals excel in a broad spectrum of applications, from engines to gearboxes, hydraulic pumps to reducers. Especially in environments characterized by high temperatures, high speeds, corrosive media, or conditions where traditional rubber oil seals fall short. Notably, our PTFE oil seals can outlast their conventional counterparts by up to 20 times, reliably sealing water, acid, gas, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, several factors demand attention: rotation speed, temperature, pressure, and medium characteristics. Proper installation is key; ensure the vertical shaft is aligned correctly to prevent tilting, and apply grease to the lip to minimize dry grinding.
