Product Description

Oil seals, also known as rotary shaft seals, are pivotal in safeguarding machinery. They are expertly designed to seal grease, liquids, or dirt, serving as a critical component that supports the seamless operation of rotating and moving systems. Their primary role is to stabilize and seal the space between stationary and moving parts within mechanical assemblies. Generally, an oil seal is composed of three essential elements:
These elements include a sealing material (a durable rubber component), resilient metal casings, and reliable springs, forming a versatile sealing assembly that adapts to various conditions.
Among the range of types are TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored for specific applications.
We present an extensive range of premium rubber materials for crafting our oil seals, thus ensuring compatibility with diverse operational requirements. These robust materials are engineered to withstand various chemicals and endure extreme temperature fluctuations, from scorching heat to icy cold.
[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.

For customizable non-standard oil seals, we use specialized materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering tailored solutions for 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 forms a crucial oil film at the interface of the lip and the shaft, achieving superior dynamic sealing through the synergy of spring pressure and material elasticity. As the shaft rotates, the lip's contraction due to frictional heat amplifies the sealing effect; when still, it maintains essential contact to preserve the integrity of the seal.

[Oil seal application fields]
Our oil seals find extensive application across engines, gearboxes, hydraulic pumps, reducers, and more, particularly in harsh conditions involving high temperatures, rapid velocities, corrosive media, or when conventional rubber oil seals fall short. Notably, PTFE oil seals offer longevity up to 20 times greater than traditional variants and proficiently seal water, acids, gases, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics meticulously. Ensure the vertical installation of the shaft to avert tilting and apply grease to the lip to diminish the risk of dry grinding.
