Product Description

Oil seals, often referred to as rotary shaft seals, are crucial in safeguarding mechanical equipment by sealing grease, liquids, and dirt. As indispensable components in any rotating or moving assembly, they stabilize the interface between stationary and moving parts. An oil seal typically comprises three essential elements:
These elements include a sealing material, which is a rubber component, along with robust metal casings and durable springs. This results in a highly adaptable sealing assembly.
Our oil seals come in a variety of types to meet diverse requirements, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring that there is a perfect match for every application.
Our extensive range of rubber materials for oil seal manufacturing ensures compatibility with a variety of operating conditions. Designed to withstand harsh chemicals and extreme temperature fluctuations, our materials guarantee exceptional performance in challenging 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.

We offer the flexibility of producing customizable non-standard oil seals using premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to specific client requirements and environmental conditions.

[Core Structural 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 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

[Principles of Oil Sealing]
The oil seal plays a vital role by forming an oil film through the interaction between the lip and the shaft. This creates dynamic sealing powered by the interplay of spring pressure and material elasticity. When in motion, frictional heat causes the lip to contract, intensifying the seal, while in a stationary state, it maintains a steadfast seal.

[Application Fields for Oil Seals]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and other high-demand equipment. They excel in conditions of high temperatures, high speeds, and exposure to corrosive media. For example, PTFE oil seals offer extraordinary longevity, lasting up to 20 times longer than conventional counterparts, while expertly sealing water, acid, gas, and more.

[Selecting and Installing Oil Seals]
To ensure impeccable performance, consider the shaft's rotational speed, temperature, pressure, and the characteristics of the medium. Properly install the vertical shaft to avert tilting, and apply grease to the lip to mitigate dry friction and extend seal life.
