Product Description

Product Description

Oil seals, also known as rotary shaft seals, are indispensable components in machinery, expertly designed to seal in grease and liquids while keeping dirt out. These seals play a crucial role in maintaining the integrity of rotating and moving assemblies by providing a stable barrier between stationary and moving parts, thereby ensuring smooth mechanical operation. Typically, an oil seal is crafted from three core elements:
A robust sealing material (rubber component), durable metal casings, and resilient springs. This combination forms a highly adaptable sealing assembly.
Our extensive range of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each engineered for specific applications.
We offer a vast array of premium rubber materials for crafting oil seals, guaranteeing their suitability for diverse operating conditions. These materials are engineered to withstand a wide spectrum of chemicals and temperature extremes, ensuring reliability in both high and low thermal 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 tailored needs, we produce customizable non-standard oil seals using high-grade materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, each selected for its resilience and performance characteristics.

[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 sealing prowess of an oil seal lies in its ability to form a protective oil film through the interaction between the lip and the shaft. This dynamic seal is achieved by harnessing the spring's pressure and the material's inherent elasticity. During operation, frictional heat causes the lip to contract, which enhances the sealing effectiveness; while at rest, it maintains a secure contact to ensure continued protection.

[Oil seal application fields]
Our oil seals find wide-ranging applications in engines, gearboxes, hydraulic pumps, reducers, and other critical equipment. They excel in challenging environments characterized by high temperatures, high speeds, and corrosive media, where conventional rubber seals may fall short. Notably, PTFE oil seals demonstrate remarkable longevity, lasting up to 20 times longer than traditional options, and they are adept at sealing diverse media such as water, acids, and gases.

[Oil seal selection and installation]
When selecting and installing oil seals, 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 mitigate dry grinding, thus ensuring optimal performance and longevity.
