Product Description

Product Description

Oil seals, often known as rotary shaft seals, are pivotal in maintaining the integrity of your machinery. They are expertly crafted to seal grease, liquids, and fend off dirt effectively. As a critical component in any rotating or moving assembly, the oil seal ensures the seamless operation by stabilizing the interface between stationary and dynamic parts of mechanical equipment. Typically, an oil seal is composed of three key elements:
A sealing material made of robust rubber, sturdy metal casings, and resilient springs. This trifecta forms a highly adaptable sealing assembly designed to meet diverse industrial demands.
Our extensive range of seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, catering to various specific applications.
We offer an impressive variety of high-grade rubber materials for crafting oil seals, ensuring they meet the demanding requirements of different operational environments. These superior rubber materials are designed to withstand an array of chemicals and endure extreme temperatures, both high and low, 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.

Our customizable non-standard oil seals are expertly manufactured using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, precisely tailored for your unique specifications.

[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 innovative oil seal leverages the interaction between the lip and the shaft to generate an oil film, achieving exceptional dynamic sealing. This is accomplished by utilizing spring pressure and the elasticity of the materials used. During rotation, the frictional heat induces the lip to contract, elevating the sealing efficacy; when the equipment is stationary, contact is maintained to ensure the seal remains intact.

[Oil seal application fields]
Our oil seals are extensively employed in engines, gearboxes, hydraulic pumps, reducers, and other equipment, especially in conditions with high temperatures, high speeds, and corrosive media, or where traditional rubber oil seals have underperformed. Notably, PTFE oil seals offer longevity, with a lifespan up to 20 times longer than conventional seals, effectively sealing water, acid, gas, and other media.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics holistically. Ensure the vertical shaft is installed to prevent tilting and apply grease to the lip to mitigate dry friction, maximizing the seal's efficiency and lifespan.
