Product Description

Oil seals, also known as rotary shaft seals, are indispensable in mechanical assemblies, expertly sealing grease, liquids, or contaminants. They play a pivotal role in stabilizing spaces between stationary and moving parts, ensuring seamless operation of mechanical equipment. An oil seal is typically composed of three critical components:
1. A sealing material (rubber component) 2. Metal casings 3. Springs. This ingenious assembly provides versatile sealing solutions for a myriad of applications.
Types of oil seals offered include the versatile TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4 models, catering to diverse sealing needs.
Our diverse selection of premium rubber materials for oil seal manufacturing guarantees optimal performance across various operating conditions. These advanced materials withstand a wide array of chemicals and extreme temperature fluctuations, both hot and cold.

[Oil seal material introduction]

Custom non-standard oil seals are available, crafted from high-grade materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your specific requirements.

[Oil seal and sealing principle]

The oil seal achieves a superior dynamic seal by forming an oil film through the contact between the lip and shaft, powered by the spring's pressure and the material's elasticity. During rotation, the lip contracts from frictional heat, enhancing the seal, while maintaining contact when stationary to ensure a lasting seal.

[Oil seal application fields]

Our oil seals are integral to engines, gearboxes, hydraulic pumps, and reducers, excelling in high-temperature, high-speed, and corrosive environments where traditional seals fail. PTFE oil seals, for example, deliver up to 20 times the lifespan of conventional seals, expertly sealing water, acid, gas, and more.

[Oil seal selection and installation]

For optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to reduce wear from dry grinding.

[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.

[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
