Product Description

Oil seals, also known as rotary shaft seals, are the unsung heroes of industrial machinery. They expertly prevent grease, liquids, and dirt from compromising equipment. An indispensable component in any rotating and moving assembly, oil seals stabilize the space between stationary and moving parts, ensuring seamless mechanical operation. Typically, these seals are crafted from three fundamental elements:
A flexible sealing material (rubber component), robust metal casings, and elastic springs, all combining to create a versatile and highly efficient sealing assembly.
We offer an extensive range of oil seal types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and many others, tailored to meet diverse industrial needs.
Our selection of rubber materials for oil seal manufacturing is both broad and specialized, catering to various demanding operating conditions. These high-performance rubbers withstand an array of chemicals and extreme temperatures, whether soaring high or plunging 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.

We provide customizable non-standard oil seals using a variety of high-grade materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, to ensure precise performance under specific conditions.

[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's ingenuity lies in creating a protective oil film through the precise contact of its lip and the shaft. This dynamic sealing is achieved by harmonizing spring pressure with material elasticity. When in motion, frictional heat ingeniously contracts the lip, boosting the seal's efficacy; when at rest, it steadfastly maintains contact, preserving the integrity of the seal.

[Oil Seal Application Fields]
Exemplifying versatility, our oil seals excel in engines, gearboxes, hydraulic pumps, reducers, and more. They are particularly effective in environments burdened with high temperatures, rapid speeds, and corrosive media, where conventional rubber seals falter. Innovative PTFE oil seals, for example, can endure up to 20 times longer than standard options, adeptly sealing water, acid, gas, and other challenging media.

[Oil Seal Selection and Installation]
To select and install the perfect oil seal, consider the shaft's rotation speed, temperature, pressure, and media characteristics comprehensively. Ensure vertical installation to avert tilting, and apply grease to the lip to mitigate dry grinding, ensuring long-lasting performance.
