Product Description

Oil seals, or rotary shaft seals, are pivotal components in any rotating or moving assembly. They ingeniously seal grease, liquids, or dirt, ensuring a meticulous stabilizing of the space between stationary and moving parts in mechanical equipment. An oil seal is skillfully composed of three essential elements:
The assembly is expertly crafted with a sealing material (rubber component), robust metal casings, and reliable springs, providing an adaptable and versatile sealing solution.
Our diverse range includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and others, meeting a wide array of sealing requirements and needs.
Delve into our expansive selection of premium rubber materials, intricately tailored for crafting high-performance oil seals. These materials are engineered to withstand a broad spectrum of chemicals and endure volatile 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 excel in creating customizable non-standard oil seals using top-tier materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring exceptional quality and performance.

[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 masterfully forms an oil film through the precise interaction between its lip and the shaft, utilizing spring pressure and material elasticity to its advantage. During rotation, frictional heat causes the lip to contract, improving the seal; while stationary, it maintains steadfast contact, ensuring the seal's integrity.

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

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