Product Description

Product Description

Oil seals, also known as rotary shaft seals, are indispensable for the effective sealing of grease, liquids, or dirt. These seals play a crucial role as a stabilizing component within any rotating or moving assembly, expertly managing the space between stationary and dynamic parts of mechanical equipment. The construction of a traditional oil seal encompasses three primary elements: a sealing material (rubber component), metal casings, and springs, creating a highly adaptable sealing assembly.
A sealing material (rubber component), metal casings, and springs. It is a versatile sealing assembly.
Types include: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others.
Our extensive array of rubber materials for oil seal manufacturing is meticulously chosen to ensure compatibility with a variety of operational environments. These superior rubber materials are resilient, capable of withstanding a wide spectrum of chemicals as well as extreme temperature conditions, whether excessively high or low, providing unparalleled 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.

We offer production of customizable non-standard oil seals using high-quality materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailoring solutions to meet unique specifications and challenging applications.

[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 functions through an intricate balance of contact between the lip and the shaft, forming an oil film that achieves dynamic sealing. This is facilitated by the combined effects of spring pressure and the elasticity of the material. During rotation, frictional heat causes the lip to contract, thereby intensifying the sealing effectiveness. In a stationary state, the lip maintains its contact to ensure the seal remains intact.

[Oil seal application fields]
Our oil seals are extensively employed across multiple domains, including engines, gearboxes, hydraulic pumps, reducers, and other machinery, especially in environments characterized by high temperatures, rapid speeds, corrosive media, or where traditional rubber oil seals have proven inadequate. PTFE oil seals, for instance, dramatically outlast conventional models by up to 20 times and proficiently seal against water, acid, gas, and various other substances.

[Oil seal selection and installation]
When selecting and installing oil seals, it is imperative to consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensuring the vertical alignment of the shaft prevents tilting, and applying grease to the lip minimizes dry friction and enhances longevity.
