Product Description

Oil seals, also known as rotary shaft seals, are indispensable components in sealing grease, liquids, and dirt, playing a crucial role in stabilizing spaces between stationary and moving parts in mechanical assemblies. An oil seal typically comprises three vital elements:
These elements include a sealing material (rubber component), metal casings, and springs, forming a highly adaptable sealing assembly.
Our lineup encompasses a variety of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others.
We offer an extensive range of premium rubber materials for manufacturing oil seals, ensuring unmatched compatibility with diverse operating conditions. These top-tier materials withstand a broad spectrum of chemicals and extreme temperatures, safeguarding performance in both high and low thermal environments.
[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.

Our customizable non-standard oil seals are crafted using advanced materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet 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)

[Key Structural Components of Oil Seals]

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

[Principle of Oil Seal and Sealing Technique]
The oil seal expertly forms an oil film through the precision contact between its lip and the shaft, achieving dynamic sealing through spring pressure and material elasticity. The lip contracts due to frictional heat when rotating, enhancing sealing efficacy, and maintains contact when stationary to uphold the seal.

[Fields of Application for Oil Seals]
Our oil seals find extensive use in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in challenging conditions such as high temperatures, fast speeds, and corrosive environments where traditional seals fall short. Particularly, PTFE oil seals offer longevity, lasting up to 20 times longer than regular seals, effectively sealing water, acids, gases, and more.

[Selection and Installation of Oil Seals]
When selecting and installing, consider shaft rotation speed, temperature, pressure, and medium characteristics holistically. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry friction.
