Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in safeguarding machinery by effectively sealing grease, liquids, and dirt. These indispensable components stabilize the space between stationary and moving parts in any rotating and moving assembly, ensuring smooth mechanical operation. The oil seal is typically composed of three essential elements:
a robust sealing material (rubber component), durable metal casings, and resilient springs, creating a versatile and highly effective sealing assembly.
Our range of oil seals includes diverse types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, allowing for a wide array of applications.
We provide an extensive selection of premium rubber materials, purposefully chosen to manufacture oil seals that excel in various demanding operating conditions. These high-performance materials are engineered to withstand an array of harsh chemicals and extreme temperatures, both high and low, ensuring reliability and longevity.
[Comprehensive Introduction to Oil Seal Materials]

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 producing customized non-standard oil seals using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet unique specifications.

[Core Structure Types of Oil Seals]

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)

[Essential 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

[Fundamental Principle of Oil Sealing]
Our oil seals master the art of sealing through the creation of an oil film, formed by the contact between the lip and the shaft. This dynamic sealing mechanism leverages the power of spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal; while at rest, it maintains contact to ensure perpetual sealing efficacy.

[Applications of Oil Seals Across Diverse Fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, expertly handling high temperatures, high speeds, corrosive media, and cases where conventional rubber seals fall short. Notably, PTFE oil seals outperform traditional options, lasting up to 20 times longer and effectively sealing water, acid, gas, and various challenging media.

[Guidance on Oil Seal Selection and Installation]
Consider critical factors such as rotation speed, temperature, pressure, and medium characteristics when selecting oil seals. Proper installation involves aligning the vertical shaft to prevent tilting and applying grease to the lip to minimize dry grinding, ensuring optimal performance and longevity.
