Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding mechanical assemblies by adeptly sealing grease, liquids, or dirt. These indispensable components stabilize the crucial spaces between stationary and moving parts, ensuring the seamless operation of mechanical equipment. Typically, an oil seal is ingeniously composed of three core elements:
A robust sealing material (rubber component), durable metal casings, and resilient springs come together to form this adaptable sealing assembly.
Explore a variety of oil seal types, including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed to meet diverse needs.
Our extensive range of high-performance rubber materials for oil seal manufacturing ensures compatibility with different operating conditions. These materials excel under various chemicals and withstand extreme temperatures, whether scorching hot or frigidly cold.
[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.

We offer customizable non-standard oil seals crafted from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, providing you with tailored solutions.

[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 sophisticated oil seal mechanism forms an oil film through the interaction between the lip and the shaft, achieving dynamic sealing by harnessing spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal; when at rest, it maintains contact to secure the seal.

[Oil seal application fields]
Our oil seals find extensive applications in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in demanding environments with high temperatures, high speeds, and corrosive media, outperforming traditional rubber oil seals. Notably, PTFE oil seals offer up to 20 times more durability, effectively sealing water, acids, gases, and other challenging media.

[Oil seal selection and installation]
Optimal oil seal selection involves a comprehensive assessment of shaft rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical installation of the shaft to prevent tilting and apply grease to the lip to minimize dry abrasion.
