Product Description

Oil seals, also known as rotary shaft seals, serve as vital protectors against grease, liquids, and dirt. As a critical component, they stabilize the interplay between static and dynamic parts in mechanical systems. Typically, an oil seal is composed of three core elements, ensuring optimal performance and reliability.
These essential elements consist of a sealing material (rubber component), robust metal casings, and resilient springs, forming a highly adaptable sealing assembly that suits various mechanical applications.
We offer a range of oil seal types, including but not limited to TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4. Each type is engineered to meet specific requirements, providing flexibility and efficiency.
Our extensive selection of premium rubber materials ensures the optimal performance of oil seals across diverse operating conditions. These materials excel in withstanding harsh chemicals and extreme temperatures, providing reliable sealing solutions for both high and low-temperature environments.
[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 requiring specialized solutions, we offer customizable non-standard oil seals crafted from advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet unique specifications and performance demands.

[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 by forming an oil film through the delicate contact between the lip and the shaft, achieving dynamic sealing with the aid of spring pressure and the natural elasticity of the material. This design ensures an enhanced sealing effect during rotation, as the lip contracts from frictional heat, while maintaining its seal when at rest.

[Oil seal application fields]
Our oil seals are indispensable across a variety of industries, prominently used in engines, gearboxes, hydraulic pumps, and reducers. They excel in environments exposed to high temperatures, high speeds, and corrosive media where conventional seals may falter. PTFE oil seals, for instance, boast a lifespan up to 20 times greater than traditional seals, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, it's crucial to account for the shaft's rotation speed, temperature, pressure, and medium characteristics. The vertical shaft must be correctly installed to prevent tilting, and grease should be applied to the lip to minimize dry friction and ensure longevity.
