Product Description

Oil seals, also renowned as rotary shaft seals, are indispensable in safeguarding machinery from grease, liquids, or dirt intrusion. As a vital component of rotating and moving assemblies, oil seals play a critical role in stabilizing the interface between stationary and moving parts within mechanical equipment. Typically, an oil seal is composed of three primary elements:
These are a sealing material (the rubber component), metal casings, and resilient springs. This versatile sealing assembly is engineered for adaptability and performance in diverse applications.
Our array of oil seal types is extensive, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed to meet specific sealing requirements.
We provide a comprehensive selection of top-grade rubber materials for crafting oil seals, ensuring their performance under varying operating conditions. These high-performance rubber materials are engineered to withstand a wide spectrum of chemicals and extreme temperatures, whether soaring high or plummeting low.
[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.

Tailor-made, non-standard oil seals can be crafted using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering bespoke sealing solutions.

[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 forms an effective oil film via the interaction between the lip and the shaft, achieving dynamic sealing through spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, thereby intensifying the sealing effect, while at rest, it maintains contact to uphold the seal.

[Oil seal application fields]
Our oil seals are widely applied in engines, gearboxes, hydraulic pumps, reducers, and various equipment, particularly in challenging environments involving high temperatures, high speeds, or corrosive media, where conventional rubber oil seals falter. PTFE oil seals, for example, can surpass traditional oil seals in longevity, lasting up to 20 times longer, and are adept at sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
To ensure optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Proper installation involves preventing tilting by mounting the shaft vertically and applying grease to the lip to minimize dry friction.
