Product Description

Product Description

 

Oil seals, often termed as rotary shaft seals, are vital components engineered to shield assemblies from grease, liquids, or dirt intrusion. As essential elements, these seals stabilize the interface between stationary and moving components within mechanical systems. Typically, a robust oil seal comprises three core elements:
A resilient sealing material (rubber component), sturdy metal casings, and tension springs. This combination forms a versatile sealing assembly with unmatched adaptability.
Available types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide spectrum of applications.
Our extensive range of premium rubber materials for oil seal manufacturing ensures compatibility across diverse operational environments. These high-grade materials withstand a wide array of chemicals and extreme temperatures, providing reliability whether in high heat or freezing conditions.
[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.

Tailor-made non-standard oil seals can be meticulously crafted using specialized materials such as fluorine rubber, silicone rubber, advanced fine rubber, and propylene rubber, tailored to meet 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]
Through precision contact between its lip and the shaft, the oil seal forms an oil film that facilitates dynamic sealing. By harnessing spring tension and material elasticity, the seal adapts to motion: contracting to enhance sealing during rotations due to frictional heat, while maintaining contact when stationary to ensure a consistent seal.

[Oil seal application fields]
Predominantly utilized in engines, gearboxes, hydraulic pumps, and reducers, these oil seals excel in high-temperature, high-speed, and corrosive environments where traditional seals falter. Notably, PTFE oil seals exhibit a lifespan up to 20 times that of conventional seals, effectively sealing water, acids, gases, and diverse media.

[Oil seal selection and installation]
A holistic assessment of the shaft's rotational speed, temperature, pressure, and media characteristics is crucial for optimal selection. Ensure the vertical installation of the shaft to prevent tilt, and apply grease to the lip to mitigate dry friction.
