Product Description

Oil seals, often referred to as rotary shaft seals, play a pivotal role in safeguarding machinery by effectively sealing grease, liquids, or dirt. These seals are indispensable components in any rotating and dynamic assembly, maintaining stability between the stationary and moving parts within mechanical equipment. Generally, an oil seal is composed of three core elements:
This includes a sealing material, typically a robust rubber component, accompanied by metal casings and resilient springs, making it a highly versatile sealing assembly.
Our range offers numerous types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, each tailored for specific applications.
We proudly offer a comprehensive selection of premium rubber materials for crafting oil seals, ensuring their adaptability to a vast array of operational conditions. Our high-performance rubbers are engineered to withstand a spectrum of chemicals and endure extreme temperatures, be it scorching heat or freezing cold.

[Oil seal material introduction]

We specialize in the customization of non-standard oil seals crafted from advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, meeting the unique demands of any application.

[Oil seal and sealing principle]

The efficiency of the oil seal is achieved through the oil film created by the contact of the lip and the shaft, utilizing spring pressure and material elasticity for dynamic sealing. During operation, the lip contracts from frictional heat, intensifying the seal's effectiveness; when not in motion, it remains in contact to uphold the seal.

[Oil seal application fields]

Oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and a multitude of other devices, especially those subjected to high temperatures, high speeds, or corrosive media, where conventional seals fall short. Notably, PTFE oil seals offer extraordinary durability, lasting up to 20 times longer than traditional variants, and are adept at sealing water, acid, gas, and additional media.

[Oil seal selection and installation]

When selecting and installing oil seals, consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. For optimal performance, ensure the vertical shaft is installed to prevent tilting and apply grease to the lip to minimize 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
