Product Description

Oil seals, elegantly known as rotary shaft seals, serve as vital guardians, meticulously sealing grease, liquids, and dirt. Acting as the heart of rotating and moving assemblies, they maintain harmony between stationary and dynamic components within mechanical equipment. These indispensable seals typically consist of three essential components:
A sophisticated sealing material (rubber component), robust metal casings, and precision-engineered springs. This assembly is celebrated for its versatility and reliability.
Diverse types of oil seals include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, along with many other specialized variants.
Our extensive array of rubber materials for oil seal manufacturing guarantees suitability for a myriad of operating conditions. These premium rubber materials are engineered to withstand an extensive range of chemicals and extreme temperatures, encompassing both high and low spectra.
[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.

Tailor-made non-standard oil seals can be crafted from elite materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring the perfect fit for any application.

[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 intricate interplay between the lip and the shaft, achieving dynamic sealing through the synergy of spring pressure and material elasticity. As it rotates, frictional heat causes the lip to contract, amplifying the sealing prowess. When at rest, it maintains its grip, safeguarding the seal's integrity.

[Oil seal application fields]
Ubiquitously employed in engines, gearboxes, hydraulic pumps, reducers, and myriad other apparatus, oil seals excel in high-temperature, high-speed, and corrosive environments where traditional rubber oil seals falter. Notably, PTFE oil seals offer an astounding longevity, enduring 20 times longer than conventional options, effectively sealing water, acids, gases, and more.

[Oil seal selection and installation]
A holistic evaluation of the shaft's rotation speed, temperature, pressure, and medium characteristics is crucial. Ensure vertical shaft installation to avert tilting and apply grease to the lip to diminish dry grinding, safeguarding the seal's performance.
