Product Description

Oil seals, also known as rotary shaft seals, are integral to the smooth operation of mechanical equipment. They expertly seal grease, liquids, or dirt, ensuring the longevity and performance of any rotating and moving assembly. Essential for stabilizing the interaction between stationary and dynamic parts, oil seals typically encompass three key elements:
Featuring a sealing material (a robust rubber component), sturdy metal casings, and resilient springs, this versatile sealing assembly delivers unmatched reliability in various applications.
Explore our array of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each designed for specific applications and conditions.
Our extensive selection of high-performance rubber materials ensures our oil seals are tailored for diverse operating environments. These materials withstand a broad spectrum of chemicals and endure extreme temperatures, both high and low, for optimal performance.
[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.

Custom non-standard oil seals can be expertly crafted using materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, catering to specific needs.

[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 leverages the contact between its lip and the shaft to form an oil film, achieving dynamic sealing through a synergy of spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, optimizing the seal. When stationary, it maintains a firm contact to ensure lasting effectiveness.

[Oil seal application fields]
Our oil seals are indispensable in engines, gearboxes, hydraulic pumps, reducers, and more, especially in challenging conditions like high temperatures, high speeds, and corrosive environments. Our PTFE oil seals, for instance, offer up to 20 times the longevity of conventional seals, efficiently sealing water, acid, gas, and beyond.

[Oil seal selection and installation]
When selecting an oil seal, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. For installation, ensure the vertical shaft is precisely positioned to avoid tilting, and apply grease to the lip to mitigate dry grinding and enhance durability.
