Product Description

Product Description

Oil seals, often referred to as rotary shaft seals, are quintessential components in mechanical assemblies. Expertly designed to seal grease, liquids, or dirt, they stabilize the crucial interface between stationary and moving parts. Comprised typically of three core components, these seals ensure smooth and efficient operations:
A robust sealing material (rubber component), durable metal casings, and resilient springs. This versatile sealing assembly is integral to performance and reliability.
Our extensive range includes types like TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse industrial applications.
We offer a broad selection of advanced rubber materials for oil seal manufacturing, tailored to meet a variety of operating conditions. These high-performance materials withstand a wide spectrum of chemicals and 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.

For specific needs, we customize non-standard oil seals using premium materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber to ensure exceptional performance.

[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 operates by forming an oil film at the lip-shaft interface, achieving dynamic sealing through spring force and material elasticity. During rotation, lip contraction due to frictional heat enhances sealing; while stationary, it maintains contact, preserving the seal.

[Oil seal application fields]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, and reducers, especially in harsh conditions like high temperatures, high-speed operations, or corrosive environments. Superior PTFE oil seals offer up to 20 times the lifespan of conventional seals, effectively sealing water, acid, gas, and beyond.

[Oil seal selection and installation]
When selecting and installing oil seals, consider shaft rotation speed, temperature, pressure, and media characteristics. Ensure the vertical shaft is installed to avoid misalignment and apply grease to the lip for reduced friction and wear.
