Product Description

Oil seals, also known in the industry as rotary shaft seals, are indispensable elements designed to ensure the integrity and performance of mechanical systems. By effectively sealing grease, liquids, or dirt, these seals are vital in maintaining a smooth operation. The oil seal plays a crucial role in any rotating or moving assembly, as it stabilizes the space between stationary and moving components. Typically, it comprises three principal components that ensure its functionality:
These components include a sealing material (often a robust rubber component), sturdy metal casings, and resilient springs. This trifecta forms a highly adaptable sealing assembly that can meet a multitude of requirements.
Our extensive range of oil seals includes various types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each crafted to meet specific demands and applications.
We provide a rich assortment of rubber materials for oil seal production, tailored to accommodate diverse operational conditions. Each high-performance rubber material is designed to withstand various chemicals and endure extreme temperatures, whether high or low, ensuring longevity and reliability.
[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.

For non-standard oil seals, customization is key. We offer production using select materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, enabling us to meet unique specifications and performance criteria.

[Core Types of Oil Seal Structures]

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

[Principles of Oil Sealing]
The sealing efficacy of an oil seal is achieved through the formation of an oil film, created by the contact between the lip and the shaft. This dynamic sealing is further enhanced by the spring's pressure and the material's elasticity. During rotation, frictional heat causes the lip to tighten, improving the seal; when motion ceases, the lip maintains contact, ensuring continued sealing integrity.

[Fields of Application for Oil Seals]
Our oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and various equipment, excelling in environments characterized by high temperatures, high speeds, or corrosive media. In situations where conventional rubber oil seals fall short, our PTFE oil seals stand out, offering up to 20 times the longevity and sealing capabilities for water, acid, gas, and more.

[Oil Seal Selection and Installation Guidelines]
When selecting and installing oil seals, factors such as rotation speed, temperature, pressure, and medium characteristics must be carefully evaluated. It is crucial to install the vertical shaft properly to prevent tilting and apply grease to the lip for reduced friction and wear, ensuring optimal performance.
