Product Description

Oil seals, also known as rotary shaft seals, are indispensable components in mechanical assemblies. They expertly seal grease, liquids, and dirt, ensuring flawless operation by bridging stationary and moving parts. An oil seal's brilliance lies in its three primary elements:
These elements include a resilient sealing material (rubber), sturdy metal casings, and robust springs, forming a versatile and durable sealing assembly.
Our diverse array of types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others.
We provide a rich selection of premium rubber materials for oil seal manufacturing. Designed to withstand tough operating conditions, these high-performance materials bravely endure diverse chemicals and extreme temperatures, both scorching and freezing.
[Introduction to Oil Seal Materials]

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.

We offer customizable non-standard oil seals crafted from materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet your specific needs.

[Core Structure Types of Oil Seals]

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)

[Essential 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

[Understanding Oil Seal and Sealing Principles]
Oil seals function by forming an oil film through the precise interaction of the lip with the shaft. This dynamic seal is perfected by the harmonious blend of spring pressure and material elasticity. Upon rotation, the lip contracts from frictional heat, enhancing the seal; when at rest, it maintains contact to uphold its sealing prowess.

[Fields of Application for Oil Seals]
Our oil seals are trusted in engines, gearboxes, hydraulic pumps, reducers, and other machinery, excelling in high temperatures, high speeds, and corrosive environments where traditional seals falter. For example, PTFE oil seals can dramatically outlast conventional alternatives by 20 times, effectively sealing water, acid, gas, and more.

[Guidelines for Oil Seal Selection and Installation]
When selecting and installing oil seals, consider shaft rotation speed, temperature, pressure, and medium characteristics. Ensure the vertical shaft is properly installed to avoid tilting, and apply grease to the lip to minimize dry grinding.
