Product Description

Oil seals, commonly known as rotary shaft seals, play a crucial role in safeguarding mechanical assemblies by sealing grease, liquids, or dirt. These indispensable components are essential for stabilizing spaces between stationary and moving parts in machinery. A typical oil seal ingeniously comprises three key elements:
A highly effective sealing material (rubber component), robust metal casings, and resilient springs, forming a versatile sealing assembly.
Variants available include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each tailored for specific applications.
We proudly offer a comprehensive array of rubber materials for crafting oil seals, ensuring tailored suitability across diverse operational environments. These superior rubber materials withstand a broad spectrum of chemicals and endure extreme temperatures, both searing and frigid.
[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.

For those requiring bespoke solutions, non-standard oil seals are customizable using specialized materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[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]
Ingeniously designed, the oil seal creates an oil film through the contact between its lip and the shaft, achieving dynamic sealing by utilizing spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, thereby enhancing the sealing effect. When stationary, it remains in contact to preserve the seal, ensuring reliable performance.

[Oil seal application fields]
Our oil seals find extensive use in engines, gearboxes, hydraulic pumps, reducers, and more, especially under challenging conditions like high temperatures, rapid speeds, and corrosive media. When conventional rubber seals falter, our PTFE oil seals stand resilient, offering up to 20 times longer durability, effectively sealing water, acid, gas, and a range of media.

[Oil seal selection and installation]
When selecting an oil seal, consider the shaft's rotation speed, temperature, pressure, and medium characteristics comprehensively. Ensure proper installation by placing the shaft vertically to prevent tilting, and apply grease to the lip to minimize dry grinding and enhance longevity.
