Product Description

Oil seals, also known as rotary shaft seals, are indispensable in maintaining the integrity of machinery by effectively sealing grease, liquids, or dirt. These vital components play a crucial role in any rotating or moving assembly, ensuring a stabilized interface between stationary and dynamic parts in mechanical systems. Typically, an oil seal comprises three core elements:
A highly adaptable sealing assembly, composed of a durable rubber sealing material, robust metal casings, and resilient springs.
Our extensive range includes numerous types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among many others.
We pride ourselves on offering a broad spectrum of top-tier rubber materials tailored for the production of oil seals, ensuring they meet the demands of various operating conditions. Our high-performance rubbers withstand a diverse array of chemicals and endure extreme temperature variations, both high and low.
[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 specialize in fabricating customizable non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, meeting the unique demands of your application.

[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 ingenious design of the oil seal forms an oil film through the interaction between the lip and the shaft, achieving dynamic sealing enhanced by the pressure from springs and the elasticity of materials. During rotation, the lip contracts due to frictional heat, boosting the seal's effectiveness; when stationary, it maintains contact to ensure a reliable seal.

[Oil seal application fields]
Our expertly engineered oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and other critical equipment. They excel in challenging scenarios characterized by high temperatures, high speeds, and corrosive media, where traditional rubber oil seals may falter. Notably, PTFE oil seals demonstrate remarkable durability, lasting up to 20 times longer than conventional types, with the capability to seal water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, carefully consider the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft alignment to prevent tilting and apply grease to the lip to minimize dry grinding for optimal performance.
