Product Description

Oil seals, also known as rotary shaft seals, are pivotal in safeguarding machinery by sealing grease, liquids, or dirt. They are critical components in any rotating and moving assembly, ensuring the stability of the space between stationary and moving parts in mechanical equipment. Typically, an oil seal is composed of three primary elements:
These include a sealing material (rubber component), metal casings, and springs, forming a versatile sealing assembly that adapts to a range of applications.
Our oil seal types encompass a wide variety, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse operational needs.
We offer an extensive selection of rubber materials for crafting oil seals, tailored to meet various operational demands. These high-performance materials withstand exposure to numerous chemicals and endure extreme temperature fluctuations, from soaring highs to freezing lows.
[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.

Our customizable non-standard oil seals are available in materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring versatility and adaptability to specific 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 achieves dynamic sealing by forming an oil film through the lip's contact with the shaft, leveraging spring pressure and material elasticity. In motion, frictional heat causes the lip to contract, enhancing sealing efficacy, while in rest, continuous contact preserves the seal.

[Oil seal application fields]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and more, especially under challenging conditions involving high temperatures, speeds, corrosive media, or where traditional seals fail. For instance, PTFE oil seals can outperform conventional ones, lasting up to 20 times longer, and are adept at sealing water, acid, gas, and various other media.

[Oil seal selection and installation]
Consider the shaft's rotation speed, temperature, pressure, and medium characteristics thoroughly. Ensure the vertical shaft is correctly installed to prevent tilting, and apply grease to the lip to minimize dry grinding.
