Product Description

Product Description

 

Oil seals, also known as rotary shaft seals, play an indispensable role in sealing grease, liquids, or dirt. They are a vital component in any rotating or moving assembly, expertly maintaining the delicate equilibrium between stationary and mobile parts within mechanical equipment. An oil seal typically comprises three core elements that work in harmony to ensure optimal performance:
A sealing material (rubber component), resilient metal casings, and robust springs. This trifecta forms a highly adaptable sealing assembly, crafted to meet diverse requirements.
We offer a comprehensive range of types: from TC, TG, TA, SA, SB, SC, to DC, MC, MG, TCV, TCN, and TC4, among numerous others, catering to every technical need.
Our extensive array of rubber materials for oil seal manufacturing ensures adaptability for myriad operating conditions. Our advanced, high-performance rubber materials withstand a wide spectrum of chemicals and endure the harshest of temperatures, both scorching hot and bitterly 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 those requiring bespoke solutions, our customizable non-standard oil seals are crafted from premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your unique specifications.

[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 expertly forms an oil film through the sophisticated interaction between the lip and the shaft. It achieves dynamic sealing with the aid of spring tension and the natural elasticity of the materials. During rotation, frictional heat causes the lip to contract, thereby reinforcing the seal. When stationary, it maintains a steadfast contact to ensure ongoing sealing efficacy.

[Oil seal application fields]
Our oil seals are essential in engines, gearboxes, hydraulic pumps, reducers, and beyond. They excel in high-temperature, high-speed, and corrosive environments, where traditional rubber oil seals falter. Notably, PTFE oil seals deliver up to 20 times the longevity of regular oil seals, effectively sealing water, acid, gas, and more.

[Oil seal selection and installation]
Consideration of the shaft's rotation speed, temperature, pressure, and medium characteristics is crucial. Proper vertical shaft installation prevents tilting, while applying grease to the lip mitigates dry grinding, ensuring seamless operation.
