Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in sealing grease, liquids, or dirt, ensuring efficient operation within mechanical systems. As an indispensable component of any rotating and moving assembly, oil seals stabilize the space between stationary and moving elements, enhancing the integrity of mechanical equipment. Typically, these seals are composed of three key elements:
A sealing material, often a robust rubber component, complemented by durable metal casings and resilient springs, form a versatile and reliable sealing assembly to cater to diverse operational demands.
Our comprehensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, providing tailored solutions for every application.
We proudly offer an extensive array of premium rubber materials for manufacturing oil seals, allowing for exceptional adaptability across various operating environments. These high-performance materials withstand a broad spectrum of chemicals and endure extreme temperatures, whether high or low, ensuring dependability across industries.
[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.

Our expertise extends to producing customizable non-standard oil seals using an array of specialized materials, including fluorine rubber, versatile silicone rubber, high-quality fine rubber, and durable propylene rubber, to meet specific client requirements.

[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

[Oil seal and sealing principle]
The innovative design of the oil seal creates an effective oil film through the contact between the lip and shaft. This dynamic sealing mechanism leverages spring pressure and the inherent elasticity of the material. During rotation, frictional heat contracts the lip, enhancing the sealing effect, while maintaining contact in a stationary state to ensure the seal remains intact.

[Oil seal application fields]
Our oil seals are extensively utilized in a myriad of applications, including engines, gearboxes, hydraulic pumps, and reducers. They shine particularly in challenging conditions such as high temperatures, high speeds, and corrosive environments, where traditional rubber oil seals fall short. For example, our PTFE oil seals offer an impressive lifespan, lasting up to 20 times longer than conventional options, and are adept at sealing water, acids, gases, and more.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to reduce dry grinding and enhance longevity.
