Product Description

Oil seals, also known as rotary shaft seals, play a crucial role in keeping grease, liquids, and dirt at bay. They are the cornerstone of any rotating or moving assembly, bridging the gap between static and dynamic components of mechanical equipment seamlessly. An oil seal is typically composed of three vital elements:
This includes a robust sealing material (such as rubber), durable metal casings, and resilient springs. Together, they form a versatile sealing assembly that ensures optimal performance.
The array of types available includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others.
We provide a diverse range of rubber materials for crafting oil seals, guaranteeing compatibility across various operational scenarios. These high-performance rubber materials are engineered to withstand a vast spectrum of chemicals and extreme temperature variations, both high and 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.

For non-standard oil seals, customization is available using superior 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]
Through the lip-shaft contact, the oil seal creates an oil film, achieving dynamic sealing by leveraging spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, enhancing the seal, while at rest, it maintains contact to ensure continuous sealing.

[Oil seal application fields]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and more, especially under high temperature, high speed, or corrosive conditions where traditional seals falter. Notably, PTFE oil seals boast up to 20 times the longevity of conventional counterparts, effectively sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
Careful consideration of the shaft's rotation speed, temperature, pressure, and medium characteristics is crucial. Ensure vertical shaft installation to prevent tilting, and apply grease to the lip to minimize dry friction.
