Product Description

Oil seals, often known as rotary shaft seals, serve a pivotal role in sealing grease, liquids, or dirt. As a vital component in any rotating or moving assembly, oil seals ensure stability and reliability by maintaining the space between stationary and moving parts within mechanical equipment. Typically, an oil seal is crafted with precision and incorporates three fundamental elements:
Sealing material (rubber component), metal casings, and springs-all culminating in a versatile sealing assembly that adapts to various applications.
Our diverse range of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, catering to a multitude of requirements.
We present an extensive selection of high-quality rubber materials for oil seal manufacturing, guaranteeing optimal suitability for a wide range of operating conditions. These high-performance rubbers withstand diverse chemicals and endure extreme temperatures, both high and low, delivering reliability in challenging 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.

For customizable non-standard oil seals, we employ premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering tailored solutions to meet specific needs.

[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 ingeniously forms an oil film through the contact between its lip and the shaft. This dynamic sealing is achieved by harnessing spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, thereby amplifying the seal; when stationary, it maintains contact, preserving its sealing prowess.

[Oil seal application fields]
Our oil seals find extensive use in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in environments marked by high temperatures, high speeds, corrosive media, and where traditional seals fall short. For instance, our PTFE oil seals outlast conventional counterparts by up to 20 times, adeptly sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, it's crucial to consider the shaft's rotation speed, temperature, pressure, and medium characteristics. A vertical shaft installation prevents tilting, while applying grease to the lip minimizes dry grinding, promoting longevity and efficiency.
