Product Description

Oil seals, often known as rotary shaft seals, play a crucial role in sealing grease, liquids, and dirt, forming the backbone of any rotating and moving assembly. These indispensable components stabilize the space between stationary and moving parts in mechanical equipment. An oil seal typically comprises three foundational elements:
The sealing assembly is composed of a robust sealing material (rubber component), durable metal casings, and resilient springs, showcasing its versatile sealing capabilities across various applications.
We offer an array of types including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, to meet diverse sealing needs.
Our broad selection of rubber materials is engineered for manufacturing oil seals, ensuring adaptability to a multitude of operating conditions. These high-performance rubbers are adept at withstanding various chemicals and extreme temperatures, whether soaring high or plunging low.
[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.

Tailored non-standard oil seals can be customized with materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering exceptional flexibility and durability.

[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 oil seal masterfully creates an oil film through the contact between its lip and the shaft, achieving dynamic sealing with spring pressure and material elasticity. While rotating, the lip contracts due to frictional heat, enhancing sealing efficiency; when stationary, it maintains contact to secure the seal.

[Oil seal application fields]
Oil seals are extensively utilized in engines, gearboxes, hydraulic pumps, reducers, and other essential equipment. They excel in scenarios with high temperatures, high speeds, and corrosive media, where traditional rubber oil seals might falter. Notably, PTFE oil seals can endure up to 20 times longer than conventional seals, efficiently sealing water, acid, gas, and other media.

[Oil seal selection and installation]
Consider the rotation speed, temperature, pressure, and medium characteristics of the shaft comprehensively. Ensure vertical shaft installation to prevent tilting and apply grease to the lip to minimize dry grinding, promoting longevity and efficiency.
