Product Description

Product Description

Oil seals, often known as rotary shaft seals, play a crucial role in maintaining the integrity of mechanical assemblies. They effectively block grease, liquids, or dirt, making them indispensable in stabilizing the gap between stationary and rotating components. Comprising essential ingredients, oil seals ensure seamless movement in machinery.
Typically, an oil seal is crafted from three core elements: a specially designed sealing material (rubber component), robust metal casings, and durable springs. This configuration leads to a highly adaptable sealing assembly suitable for diverse applications.
Various types include the well-recognized TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among numerous others, each tailored to specific needs.
Our extensive range of premium rubber materials for oil seal production guarantees optimal performance under varying operating conditions. These cutting-edge materials stand resilient against a spectrum of chemicals and withstand extreme temperature fluctuations, ensuring reliable sealing under any circumstance.
[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 high-grade materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to specific industrial 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]
By establishing an oil film through lip-to-shaft contact, our oil seal achieves dynamic sealing, thanks to the synergetic action of spring pressure and material elasticity. As the shaft rotates, frictional heat causes the lip to contract, reinforcing the seal, while during stationary phases, it ensures unwavering contact to maintain an airtight seal.

[Oil seal application fields]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and similar equipment, particularly under challenging conditions such as high temperatures, rapid speeds, corrosive environments, or where traditional seals falter. Notably, PTFE oil seals excel with a lifespan up to 20 times longer than standard types, capable of sealing diverse media like water, acid, and gas.

[Oil seal selection and installation]
When selecting and installing oil seals, comprehensive consideration of shaft rotation speed, temperature, pressure, and medium characteristics is vital. Ensuring vertical shaft installation prevents misalignment, while applying grease to the lip minimizes dry friction, prolonging seal longevity.
