Product Description

Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in mechanical assemblies, safeguarding against the intrusion of grease, liquids, or dirt. These indispensable components maintain the delicate balance between stationary and moving parts, ensuring smooth operation and longevity of the equipment. Typically, an oil seal is composed of three essential elements:
The assembly includes a sealing material (rubber component), sturdy metal casings, and resilient springs, showcasing its versatility in a variety of applications.
Our range of oil seal types encompasses TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, offering tailored solutions for diverse needs.
We provide an extensive selection of premium rubber materials for oil seal manufacturing, catering to varied operational demands. Our high-performance materials are engineered to withstand a spectrum of chemicals and extreme temperatures, ensuring reliability in both high and low-temperature environments.
[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.

Customizable non-standard oil seals can be expertly crafted using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, delivering superior performance tailored 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]
Our oil seals achieve an effective dynamic sealing mechanism by forming an oil film through precise contact between the lip and shaft. Utilizing spring pressure and the innate elasticity of the material, our seals ensure optimal performance. During rotation, frictional heat causes the lip to contract, enhancing the seal; when stationary, it maintains contact to preserve integrity.

[Oil seal application fields]
Our oil seals excel in engines, gearboxes, hydraulic pumps, reducers, and other equipment, particularly in challenging scenarios involving high temperatures, high speeds, corrosive media, or where traditional seals falter. Notably, PTFE oil seals offer exceptional durability, lasting up to 20 times longer than conventional counterparts, effectively sealing water, acid, gas, and more.

[Oil seal selection and installation]
For optimal selection and installation, consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry friction, extending service life.
