Product Description

Oil seals, also known in the industry as rotary shaft seals, are indispensable in the manufacturing and engineering worlds. These seals are pivotal for containing grease, liquids, or preventing the ingress of dirt. They form a crucial barrier within any assembly involving rotation and movement, ensuring stability between the stationary and moving components of mechanical equipment. An oil seal is typically crafted with three essential elements:
These elements include a sealing material, often a high-quality rubber component, robust metal casings, and durable springs, making it a versatile and efficient sealing assembly.
The variety of oil seals includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, catering to a wide array of needs.
Our extensive range of rubber materials for oil seal production ensures adaptability to diverse operating conditions. These high-performance materials can withstand an impressive spectrum of chemicals and extreme temperature variations, from scorching heat to icy cold.
[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 capability to produce customizable non-standard oil seals using specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific requirements.

[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 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 Behind Oil Seal Functionality]
Our oil seals operate by creating a fine oil film through the strategic contact between the lip and the shaft. This design achieves dynamic sealing through a synergy of spring pressure and the inherent elasticity of the materials. During rotation, the lip efficiently contracts due to frictional heat, enhancing its sealing capability. When stationary, it maintains its contact to preserve the integrity of the seal.

[Applications of Oil Seals]
Oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and numerous other types of equipment. They excel in high-temperature, high-speed, or corrosive environments where traditional seals may falter. Notably, PTFE oil seals offer longevity up to 20 times greater than conventional seals and adeptly seal water, acid, gas, and a variety of other media.

[Guidelines for Oil Seal Selection and Installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure that the vertical shaft is aligned to prevent tilting, and apply grease to the lip to minimize dry friction.
