Product Description

Oil seals, often known as rotary shaft seals, are vital components in mechanical assemblies. They expertly seal grease, liquids, and dirt, thereby stabilizing the space between static and dynamic parts within machinery. Each oil seal is ingeniously crafted with three primary elements:
A robust sealing material made from rubber, durable metal casings, and resilient springs. Together, they form a versatile and reliable sealing assembly suitable for myriad applications.
Types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, offering a comprehensive range to fit diverse needs.
Our offerings include an extensive array of premium rubber materials that are meticulously selected to craft oil seals, ensuring they meet the demands of various conditions. These elite materials withstand a broad spectrum of chemicals as well as extreme temperatures, 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 crafting customizable non-standard oil seals using superior materials such as fluorine rubber, silicone rubber, 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]
An oil seal works by forming an oil film through the contact between its lip and the shaft, achieving a dynamic seal using spring pressure and material elasticity. The lip contracts due to frictional heat when rotating, enhancing the seal's efficacy; it maintains contact even when stationary to preserve integrity.

[Oil seal application fields]
Our oil seals are indispensable across engines, gearboxes, hydraulic pumps, reducers, and beyond, thriving in high-temperature, high-speed, and corrosive conditions, where conventional seals falter. PTFE oil seals excel with longevity up to 20 times greater, and adeptly seal water, acid, gas, and more.

[Oil seal selection and installation]
Consideration of the shaft's rotation speed, temperature, pressure, and medium characteristics is crucial. Ensure proper installation by maintaining the vertical alignment of the shaft to prevent tilting and apply grease to the lip to mitigate dry grinding.
