Product Description

Oil seals, also known as rotary shaft seals, are indispensable components in mechanical machinery. They serve the crucial function of sealing grease, liquids, or dirt, maintaining the integrity of rotating and moving assemblies. By stabilizing the gap between stationary and moving parts, oil seals ensure the seamless operation of various mechanical equipment. Typically, these essential devices are comprised of three core elements:
A sophisticated assembly of sealing material (rubber component), robust metal casings, and resilient springs, making it an incredibly versatile sealing solution.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many more, catering to diverse needs.
We provide an extensive array of high-quality rubber materials for crafting oil seals, each carefully chosen to withstand a variety of operating conditions. These premium materials offer exceptional resistance to chemicals and can endure extreme temperatures, ensuring performance consistency regardless of environmental challenges.
[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 are available, crafted from sophisticated materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring a perfect fit for specific applications.

[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 operates by forming an oil film as the lip meets the shaft, achieving dynamic sealing with the aid of spring pressure and the material's inherent elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal, while in a stationary state, contact is maintained to ensure ongoing protection.

[Oil seal application fields]
Our high-performance oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, and reducers, especially in demanding situations involving high temperatures, rapid speed, or corrosive environments where traditional seals fall short. PTFE oil seals, in particular, boast a lifespan up to 20 times longer than ordinary seals, adept at sealing diverse media like water, acid, and gas.

[Oil seal selection and installation]
When selecting and installing an oil seal, consider the shaft's rotation speed, temperature, pressure, and medium characteristics holistically. It's crucial to mount the shaft vertically to avoid tilting and to apply grease to the lip to minimize dry friction and extend the seal's life.
