Product Description

Oil seals, or rotary shaft seals, are the unsung champions of machinery, adeptly preventing grease, liquids, or dirt from compromising the system's performance. These essential components maintain stability between stationary and moving parts in mechanical equipment, ensuring both reliability and operational efficiency. Typically, an oil seal incorporates three core elements:
The sealing assembly is a marvel of precision engineering, featuring a sealing material (rubber component), metal casings, and springs. This versatile design is synonymous with durability and dependability.
Discover our expansive selection of seals, including types like TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the groundbreaking TC4, among others.
Our collection of high-performance rubber materials for oil seals is unmatched, expertly designed to endure exposure to a vast array of chemicals and extreme temperatures. Crafted to perfection, they operate seamlessly across various conditions, whether enduring 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.

For specialized requirements, we provide custom non-standard oil seals crafted from unique materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, delivering tailored solutions for your distinct challenges.

[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 an intricate principle, forming an oil film through the dynamic interaction between the lip and the shaft. By leveraging spring pressure and the natural elasticity of materials, it guarantees a strong seal. During operation, frictional heat causes the lip to contract, enhancing the seal, while when inactive, it retains its grip to ensure integrity.

[Oil seal application fields]
Our oil seals are crucial in engines, gearboxes, hydraulic pumps, reducers, and more. They thrive in high-temperature, high-speed, and corrosive environments where conventional seals may falter. For instance, our PTFE oil seals boast a durability up to 20 times greater than traditional seals, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, it is crucial to consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure a vertical installation to avoid tilting, and apply grease to the lip to prevent dry grinding, thereby prolonging the lifespan and enhancing the efficiency of the seal.
