Product Description

Product Description

Oil seals, also known as rotary shaft seals, are indispensable in mechanical systems. They expertly prevent leaks and block contaminants such as grease, liquids, or dirt from infiltrating crucial components. As a linchpin in moving assemblies, these seals ensure seamless integration between stationary and dynamic parts. Each oil seal is ingeniously crafted with three primary elements:
The trio of components includes a resilient sealing material (rubber component), sturdy metal casings, and robust springs. Together, they form a highly adaptable sealing assembly, ensuring effective performance across diverse applications.
Our product range covers a spectrum of types including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, among others.
Explore our extensive array of rubber materials designed for crafting oil seals, tailored to withstand various operational demands. These high-performance materials boast resilience against a myriad of chemicals and endure extreme temperature fluctuations, both high and 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.

For specialized applications, we offer fully customizable non-standard oil seals. Materials include premium options like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, ensuring top-tier adaptability.

[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 innovative design of the oil seal employs an oil film generated by the lip's contact with the shaft. This ensures dynamic sealing through the synergistic effect of spring pressure and material elasticity. During rotation, frictional heat causes the lip to contract, amplifying sealing efficiency, while in rest, it holds firm, preserving the seal integrity.

[Oil seal application fields]
Our oil seals are engineered for use in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, outperforming traditional seals. Remarkably, PTFE oil seals enhance durability by lasting up to 20 times longer, effectively sealing diverse media like water, acid, and gas.

[Oil seal selection and installation]
When selecting and installing oil seals, account for factors such as rotation speed, temperature, pressure, and the shaft's medium characteristics. Ensure the vertical alignment of the shaft to prevent tilting and apply grease to the lip for reduced wear and tear.
