Product Description

Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in maintaining the seamless operation of mechanical systems by preventing the escape of lubricants and blocking the intrusion of contaminants. They form a vital part of any rotating or moving assembly, bridging the gap between stationary and dynamic components with precision. An oil seal is composed of three key elements:
A dynamic combination of sealing material (rubber component), metal casings, and springs. This trio constitutes a highly adaptable sealing assembly.
Explore our extensive range of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
Our extensive array of rubber materials for oil seal manufacturing guarantees adaptability to diverse operational environments. These superior rubber materials withstand a wide spectrum of chemicals and extreme temperatures, delivering consistent performance in both high and low-temperature scenarios.
[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.

We offer customizable, non-standard oil seals crafted from advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet unique requirements.

[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 operates on a sophisticated principle, forming an oil film via contact between its lip and the shaft. This dynamic interaction achieves effective sealing through the synergistic action of spring pressure and material elasticity. During rotation, the lip contracts due to friction-generated heat, enhancing the seal, while maintaining contact in a stationary state to ensure ongoing protection.

[Oil seal application fields]
Our oil seals are extensively utilized across engines, gearboxes, hydraulic pumps, reducers, and other equipment, excelling in high-temperature, high-speed, and corrosive media scenarios. Exemplifying their durability, PTFE oil seals outperform traditional variants, lasting up to 20 times longer, effectively sealing 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 for optimal performance. Ensure vertical shaft installation to avoid tilting and apply grease to the lip, reducing the risk of dry grinding.
