Product Description

Oil seals, also known as rotary shaft seals, are indispensable components in mechanical systems, expertly designed to prevent the ingress of grease, liquids, or dirt. These seals play a pivotal role in safeguarding the space between stationary and dynamic parts, ensuring smooth operation of mechanical assemblies. The quintessential oil seal is composed of three core components:
The essential elements include a resilient sealing material (primarily rubber), robust metal casings, and durable springs, forming a versatile and highly effective sealing assembly.
We offer an extensive array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4 variety, among others.
Our range of rubber materials for oil seals is vast, catering to diverse operational needs. These premium materials are engineered to withstand aggressive chemicals and extreme temperature fluctuations, promising reliability in both high and low thermal conditions.
[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 non-standard oil seals, we provide customization using superior materials, including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, meeting specific application 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 sophisticated design of the oil seal facilitates the formation of an oil film via the interplay between the lip and shaft. This dynamic sealing is accomplished through the synergy of spring tension and material flexibility. As rotation induces frictional heat, the lip's contraction enhances sealing efficacy. Even when idle, the seal maintains its integrity by staying in contact.

[Oil seal application fields]
Our oil seals are integral components in engines, gearboxes, hydraulic systems, and reducers, thriving in environments characterized by high temperatures, rapid speeds, and corrosive media. When traditional rubber seals falter, our PTFE oil seals excel, offering durability up to 20 times more and effectively sealing water, acid, gas, and diverse media.

[Oil seal selection and installation]
A comprehensive evaluation of rotational speed, temperature, pressure, and medium properties is crucial for optimal selection. Correct vertical shaft installation is essential to avert tilt, and applying grease to the lip reduces the risk of dry friction.
