Product Description

Oil seals, also known as rotary shaft seals, are vital components in any rotating or moving assembly. They expertly seal grease, liquids, or dirt, ensuring the fluid integrity and longevity of mechanical equipment. Serving as a stabilizing force between stationary and moving parts, oil seals are indispensable in maintaining operational efficiency. Typically, an oil seal encompasses three core elements:
The sealing material, often a robust rubber component, metal casings, and resilient springs. This versatile sealing assembly is engineered for a broad range of applications.
Our lineup includes various types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, providing tailored solutions for specific needs.
We offer an extensive array of superior rubber materials for crafting oil seals, each chosen for their adaptability to diverse operational scenarios. These high-performance materials withstand an array of chemicals and tolerate extreme temperatures, ensuring reliability under the harshest conditions.
[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 customizable non-standard oil seals are crafted from a selection of premium materials, including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet specific performance 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 sophisticated design of the oil seal creates an oil film through the precise contact between the lip and the shaft. This dynamic sealing is achieved by harnessing spring pressure and material elasticity. When in motion, the lip contracts due to frictional heat, enhancing the seal; when stationary, it maintains contact to ensure continued sealing efficacy.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and other machinery. They are particularly effective in high-temperature, high-speed, and corrosive environments where conventional seals may fail. For example, PTFE oil seals provide up to 20 times the lifespan of traditional seals, adeptly handling water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the rotation speed, temperature, pressure, and medium characteristics of the shaft. Ensure a vertical installation to prevent tilting and apply grease to the lip to minimize dry friction, thereby extending the seal's lifespan.
