Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in the machinery world. These indispensable components efficiently prevent the leakage of grease, liquids, or dirt, maintaining an impeccable seal within any rotating or moving assembly. Oil seals adeptly bridge the gap between stationary and moving parts of mechanical equipment, ensuring smooth operation and longevity. Typically, an oil seal is ingeniously composed of three fundamental elements:
A sophisticated blend of a sealing material (rubber component), robust metal casings, and resilient springs. This versatile sealing assembly is designed to cater to a wide range of applications with commendable adaptability.
A multitude of types are available to suit diverse needs: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering a tailored solution for every sealing challenge.
Our extensive selection of premium rubber materials empowers the manufacturing of oil seals to excel under varied operating conditions. Our high-performance materials endure a spectrum of chemicals and withstand extreme temperatures, whether scorching hot or icy cold, ensuring reliability and durability.
[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 are adept at producing customizable non-standard oil seals, utilizing materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, to perfectly meet your specific needs and operational demands.

[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]
Ingeniously engineered, the oil seal crafts an oil film via the precise contact between the lip and the shaft. This dynamic sealing marvel leverages spring pressure and material elasticity. During rotation, frictional heat prompts the lip to contract, enhancing the seal, while at rest, the lip maintains contact to ensure a steadfast seal.

[Oil seal application fields]
Our oil seals are extensively utilized across various high-demand applications, including engines, gearboxes, hydraulic pumps, and reducers. They are particularly effective in environments of high temperatures, high speeds, and corrosive media, where conventional rubber oil seals may falter. PTFE oil seals, with their impressive longevity—lasting up to 20 times longer—securely handle water, acid, gas, and other challenging media.

[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 comprehensively. Ensure the vertical shaft is installed without tilting, and apply grease to the lip to minimize dry friction, maximizing efficiency and lifespan.
