Product Description

Oil seals, also known as rotary shaft seals, are indispensable marvels in the world of mechanical engineering. Their primary duty is to impeccably seal grease, liquids, or dirt, ensuring flawless operation. As a vital cog in any rotating and moving assembly, the oil seal plays a heroic role in stabilizing the space between stationary and moving parts, safeguarding the integrity of mechanical equipment. An oil seal's magic resides in its three fundamental elements:
These elements include a top-tier sealing material (the dependable rubber component), robust metal casings, and resilient springs. Together, they form a versatile and dynamic sealing assembly, ready to conquer challenges.
Embrace the diversity with our extensive types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, each engineered for specific tasks.
Our array of rubber materials for oil seals is as diverse as the challenges they meet. Designed for excellence, these high-performance rubbers adapt seamlessly to varied operating conditions, providing unmatched resistance to a spectrum of chemicals and temperature extremes, whether sizzling hot or freezing cold.
[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.

Harness the potential of customization with our non-standard oil seals, crafted from premier materials including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to meet unique demands.

[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]
Witness the brilliance of oil sealing as the lip and shaft unite to create an oil film, achieving dynamic sealing through a perfect blend of spring pressure and material elasticity. When in motion, the lip contracts due to frictional heat, boosting the seal; at rest, it holds steady, ensuring uninterrupted protection.

[Oil seal application fields]
Our oil seals shine in engines, gearboxes, hydraulic pumps, reducers, and more. When faced with high temperatures, rapid speeds, or corrosive environments, our advanced PTFE oil seals outperform traditional counterparts, lasting up to 20 times longer and sealing diverse media such as water, acid, and gas with unwavering precision.

[Oil seal selection and installation]
Comprehensive assessment of shaft rotation speed, temperature, pressure, and medium characteristics is crucial. Precise installation is key: maintain vertical alignment to prevent tilting, and generously apply grease to the lip for smooth, frictionless performance.
