Product Description

Product Description

 

Discover the essential role of oil seals, often known as rotary shaft seals, in safeguarding and sealing your machinery. These components are indispensable in maintaining the integrity of moving assemblies, expertly sealing grease, liquids, or dirt to create a dependable barrier. Every oil seal serves as a stabilizing force between stationary and moving parts in mechanical equipment, ensuring smooth and efficient operation. Typically, an oil seal is composed of three core elements:
It includes a robust sealing material (rubber component), reinforced metal casings, and resilient springs, crafting a versatile and reliable sealing assembly.
Explore a wide array of types including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored to meet unique requirements.
Our offerings include an extensive range of rubber materials designed specifically for oil seal manufacturing, ensuring adaptability to various operating conditions. These high-performance materials withstand a broad spectrum of chemicals and endure extreme temperatures, both high and low, providing robust reliability.
[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 superior materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored for 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]
Our oil seals masterfully create an oil film through strategic lip and shaft contact, achieving dynamic sealing with the synergy of spring pressure and material elasticity. As rotation occurs, the lip contracts due to frictional heat, heightening the sealing effect. When stationary, it maintains a firm contact, safeguarding the seal.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, excelling in high-temperature, high-speed, and corrosive environments. They are particularly beneficial where traditional rubber oil seals fall short. For example, PTFE oil seals offer up to 20 times the longevity of conventional types, efficiently sealing water, acid, gas, and more.

[Oil seal selection and installation]
Consideration of shaft rotation speed, temperature, pressure, and medium characteristics is crucial. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry grinding, optimizing seal longevity and performance.
