Product Description

Oil seals, also known as rotary shaft seals, are indispensable in sealing grease, liquids, or dirt. As a pivotal component of any rotating and moving assembly, they stabilize the space between stationary and moving parts in mechanical equipment. Typically, an oil seal is composed of three fundamental elements:
A sealing material (rubber component), metal casings, and springs. This combination results in a versatile and effective sealing assembly.
Types of oil seals encompass a variety of options including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored for specific applications.
We offer an extensive array of rubber materials for oil seal manufacturing, ensuring optimal performance across diverse operating conditions. These high-performance materials are designed to withstand a wide range of chemicals and extreme temperatures, whether blistering hot or freezing cold.

[Oil seal material introduction]

We specialize in creating customizable, non-standard oil seals with premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific requirements.

[Oil seal and sealing principle]

The oil seal achieves dynamic sealing by forming an oil film through the interaction of the lip and shaft, leveraging spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the sealing effect; it retains contact when stationary to ensure seal integrity.

[Oil seal application fields]

Our oil seals excel in demanding applications like engines, gearboxes, and hydraulic systems, performing exceptionally well in high-temperature, high-speed, or corrosive environments. PTFE oil seals, for example, can last up to 20 times longer than traditional seals, efficiently sealing elements like water, acid, and gas.

[Oil seal selection and installation]

Consideration of shaft variables such as rotation speed, temperature, pressure, and medium characteristics is crucial. The vertical shaft should be installed to prevent tilting, and grease should be applied to the lip to minimize dry grinding, ensuring optimal performance.

[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.

[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
