Product Description

Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding machinery by sealing grease, liquids, or dirt. They are indispensable to any rotating or moving assembly, ensuring stability between stationary and dynamic parts. Typically crafted from three essential components:
the sealing material (a robust rubber component), metal casings, and resilient springs. This combination creates a highly adaptable sealing assembly.
Our extensive range includes types like TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others.
We proudly offer a broad spectrum of premium rubber materials for manufacturing oil seals, each tailored to thrive under diverse operational conditions. These materials are engineered to resist a wide array of chemicals and endure the harshest of temperatures, be it scorching heat or freezing 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.

Our customizable, non-standard oil seals can be crafted from an array of materials including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to specific needs.

[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]
Oil seals ingeniously create an oil film through the interaction of the lip and shaft, achieving dynamic sealing via spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, enhancing sealing efficiency, while at rest, it maintains contact to uphold the seal.

[Oil seal application fields]
These seals are indispensable in engines, gearboxes, hydraulic pumps, and reducers, excelling in high-temperature, high-speed, and corrosive environments where conventional seals falter. For instance, PTFE oil seals can outlast traditional ones by 20 times, effectively sealing water, acid, gas, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, factors like shaft rotation speed, temperature, pressure, and medium characteristics must be evaluated. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to minimize dry friction.
