Product Description

Product Description

Oil seals, also known as rotary shaft seals, are indispensable guardians in mechanical equipment, expertly sealing grease, liquids, or dirt. These seals form the backbone of rotating and moving assemblies, maintaining the critical balance between stationary and moving components. Each oil seal is meticulously crafted with three core elements:
These three components include the sealing material (rubber component), metal casings, and robust springs, coming together to form a highly adaptable sealing assembly.
Our oil seal offerings encompass a wide range of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
We take pride in offering an extensive variety of rubber materials for oil seal manufacturing, ensuring perfect compatibility with diverse operating conditions. Our high-performance rubber materials are designed to withstand a broad spectrum of chemicals and extreme temperatures, whether intense heat or severe cold.
[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.

Our production capabilities extend to crafting customizable non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[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 operates by forming an oil film through precise lip-to-shaft contact, achieving dynamic sealing with the aid of spring pressure and material elasticity. As the shaft rotates, frictional heat causes the lip to contract, enhancing the sealing effect; when stationary, it maintains continuous contact to secure the seal.

[Oil Seal Application Fields]
Our oil seals excel in a wide range of applications, including engines, gearboxes, hydraulic pumps, and reducers, especially in demanding environments featuring extreme temperatures, high speeds, or corrosive media. PTFE oil seals, in particular, outlast conventional seals by up to 20 times and can effectively seal water, acids, gases, and more.

[Oil Seal Selection and Installation]
To ensure optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. It's crucial to install the vertical shaft to prevent tilting and apply grease to the lip, minimizing frictional wear.
