Product Description

Product Description

Revel in the ingenuity of our rotary shaft seals, commonly recognized as oil seals, which diligently safeguard against grease, liquids, or dirt infiltration. A pivotal component in any rotating and moving assembly, these seals masterfully stabilize the interface between stationary and dynamic parts in mechanical apparatus. Traditionally, an oil seal is comprised of three core components:
A robust sealing material (rubber component), resilient metal casings, and dynamic springs, creating a versatile sealing assembly that adapts to myriad applications.
Our array of types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse needs.
Choose from our extensive range of premium rubber materials crafted for oil seals, ensuring exceptional adaptability to various operational environments. These high-performance materials withstand exposure to a spectrum of chemicals and endure extreme temperature fluctuations.
[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.

We offer the flexibility of producing bespoke non-standard oil seals using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your specific 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]
Our oil seal achieves dynamic sealing through an oil film generated by the lip-shaft contact, leveraging both spring pressure and material elasticity. During rotation, the lip contracts due to frictional heat, enhancing the seal; when stationary, it maintains contact to secure the sealing integrity.

[Oil seal application fields]
Our oil seals find widespread application in engines, gearboxes, hydraulic pumps, and reducers, particularly excelling in high-temperature, high-speed, and corrosive environments. When traditional rubber seals fall short, PTFE oil seals shine, boasting durability up to 20 times longer and capable of sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
Consider the shaft's rotational speed, temperature, pressure, and the medium's characteristics meticulously. Ensure vertical installation to prevent tilting and apply grease on the lip to minimize dry grinding, prolonging the seal’s life.
