Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding mechanical equipment. These essential components are adept at sealing grease, liquids, or dirt, maintaining the delicate balance between stationary and moving parts in any machinery setup. Typically, an oil seal is comprised of three vital elements:
A robust sealing assembly consisting of a rubber component, durable metal casings, and resilient springs. This versatile construction ensures reliability and efficacy in various applications.
Our diverse range of oil seal types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
We offer an expansive selection of premium rubber materials for crafting oil seals, each engineered for specific operating conditions. These high-performance materials demonstrate exceptional resilience, withstanding a wide array of chemicals and extreme temperature fluctuations.
[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, customization is available using materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, adapting to your precise 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's excellence lies in its unique sealing mechanism, achieved through the contact between the lip and shaft, forming an effective oil film. The dynamic sealing is enhanced by the spring's pressure and the material's elastic properties. During rotation, frictional heat causes the lip to contract, strengthening the seal. When static, it remains in contact, maintaining the seal effortlessly.

[Oil seal application fields]
Our oil seals are integral to engines, gearboxes, hydraulic pumps, reducers, and beyond, excelling in high temperature, high-speed, and corrosive environments. In cases where traditional rubber oil seals underperform, PTFE oil seals deliver unmatched longevity, lasting up to 20 times longer, and proficiently sealing water, acid, gas, and more.

[Oil seal selection and installation]
To ensure optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium nature. Installation should ensure the vertical alignment of the shaft to prevent tilting, and applying grease to the lip can significantly reduce dry grinding, enhancing longevity.
