Product Description

Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in sealing grease, liquids, or keeping out dirt. They are indispensable in any rotating or moving assembly, serving to stabilize the space between stationary and moving components within mechanical equipment. An oil seal typically comprises three essential elements:
These elements include a sealing material (rubber component), robust metal casings, and resilient springs, forming a versatile sealing assembly that ensures optimal performance.
The types of oil seals available include TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among a plethora of other specialized variants.
Our extensive range of rubber materials for oil seal manufacturing are carefully chosen to meet various operational conditions. These high-performance materials are capable of withstanding a wide array of chemicals and extreme temperatures, ensuring reliability in both high and low-temperature 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 customization of non-standard oil seals, using materials such as superior fluorine rubber, versatile silicone rubber, fine rubber composites, and durable propylene rubber, to meet unique specifications.

[Types of Oil Seal Core 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

[The Principle Behind Oil Seal and Sealing Efficiency]
The oil seal achieves its dynamic sealing prowess by forming an oil film through the contact between its lip and the shaft, using the elasticity of the material and the pressure of the spring. As the shaft rotates, frictional heat causes the lip to contract, enhancing the sealing effect. When at rest, the lip maintains contact, preserving the seal's integrity.

[Fields of Application for Oil Seals]
Oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and other machinery. They are particularly effective in conditions involving high temperatures, high speeds, corrosive media, or where traditional rubber oil seals have underperformed. Notably, PTFE oil seals deliver remarkable durability, lasting up to 20 times longer than conventional seals, and can adeptly seal water, acid, gas, and other challenging media.

[Guidelines for Oil Seal Selection and Installation]
When selecting an oil seal, consider the shaft's rotation speed, temperature, pressure, and medium characteristics holistically. Ensure the vertical installation of the shaft to avoid misalignment, and apply grease to the lip to minimize dry grinding and enhance longevity.
