Product Description

Product Description

Oil seals, also heralded as rotary shaft seals, serve a pivotal role in sealing grease, liquids, or dirt efficiently. They are indispensable components in any rotating and moving assembly, diligently maintaining the balance between stationary and moving parts within mechanical equipment. Typically, an oil seal is composed of three crucial elements:
These vital elements include a sealing material (rubber component), robust metal casings, and resilient springs. This combination forms a profoundly versatile sealing assembly.
Our offerings encompass a wide array of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, amongst others.
We present an extensive variety of premium rubber materials for manufacturing oil seals, ensuring compatibility with diverse operating conditions. These high-performance materials are engineered to withstand a broad spectrum of chemicals and endure extreme temperatures, whether scorching or 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.

We specialize in the production of customizable non-standard oil seals, utilizing advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber to meet specific demands.

[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 oil seal functions by forming an oil film through the interaction between the lip and the shaft, achieving dynamic sealing through a combination of spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing sealing power; when stationary, it sustains contact to maintain the seal's integrity.

[Oil seal application fields]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and various other equipment, especially under high temperatures, high-speed conditions, corrosive environments, or where traditional rubber oil seals fall short. Remarkably, PTFE oil seals offer durability up to 20 times greater than standard oil seals, adeptly sealing water, acid, gas, and more.

[Oil seal selection and installation]
Considerations for selecting and installing oil seals include the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to avert tilting and apply grease to the lip to mitigate dry friction.
