Product Description

Product Description

 

Oil seals, also known as rotary shaft seals, are indispensable in the world of mechanical engineering. They serve the crucial role of sealing in grease, liquids, or preventing dirt ingress, and are vital components for all rotating and moving assemblies. By stabilizing the space between stationary and dynamic parts, these seals are the unsung heroes ensuring efficient operation of mechanical equipment. An oil seal typically comprises three core elements:
A sealing material made from a robust rubber component, durable metal casings, and resilient springs. This trinity forms a versatile sealing assembly, adept at meeting diverse application demands.
Our range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
We pride ourselves on offering a vast spectrum of advanced rubber materials for oil seal production, ensuring compatibility across various operational demands. These materials are designed to withstand hostile environments, enduring exposure to an array of chemicals and extreme temperature variations, both scorching and frigid.
[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 niche requirements, we specialize in crafting customizable non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet your specific needs.

[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 genius of the oil seal lies in its ability to create an oil film through precise lip and shaft contact, ensuring dynamic sealing by harnessing the power of spring pressure and material elasticity. As the shaft rotates, frictional heat compacts the lip, amplifying the seal's effectiveness; when stationary, it maintains its grip to ensure a steadfast seal.

[Oil seal application fields]
Our oil seals find their place in engines, gearboxes, hydraulic pumps, reducers, and more-particularly in high-temperature, high-speed, or corrosive environments where ordinary rubber oil seals fall short. Notably, PTFE oil seals exemplify durability, outlasting conventional seals by up to 20 times, and confidently sealing water, acids, gases, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, factors like shaft rotation speed, temperature, pressure, and medium characteristics are vital considerations. Proper installation includes positioning the vertical shaft to prevent tilt and applying grease to the lip, reducing the risk of dry grinding and extending the seal's life.
