Product Description

Oil seals, or rotary shaft seals, are integral to any rotating or moving assembly. They masterfully seal grease, liquids, or dirt, meticulously stabilizing the space between stationary and moving parts in mechanical equipment. An oil seal is composed of three essential elements:
The assembly includes a sealing material (rubber component), robust metal casings, and reliable springs, offering a versatile sealing solution.
Our types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse sealing needs.
Explore our extensive selection of premium rubber materials, tailored for manufacturing high-performance oil seals. These materials are engineered to withstand an array of chemicals and endure extreme temperatures, both high and low.
[Introducing Oil Seal Materials]

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-quality materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[Oil Seal Core Structure Types]

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)

[Essential 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 Its Sealing Principle]
The oil seal crafts an oil film through the precise contact between its lip and the shaft. This dynamic sealing leverages spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal; while stationary, it maintains contact, preserving the seal's integrity.

[Fields of Oil Seal Applications]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and other equipment. They excel in high-temperature, high-speed, and corrosive environments, outperforming traditional rubber oil seals. For instance, PTFE seals offer up to 20 times the lifespan, effectively sealing water, acid, gas, and more.

[Selection and Installation of Oil Seals]
Consider the shaft's rotational speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to mitigate dry grinding.
