Product Description

Product Description

Oil seals, often known as rotary shaft seals, are a vital safeguard for your machinery. They prevent the ingress of contaminants like dirt, while sealing in lubricants and fluids essential for smooth operation. Acting as a crucial component in any rotating or moving assembly, oil seals maintain balance between stationary and dynamic parts, enhancing the lifespan and efficiency of mechanical equipment. These indispensable seals are composed of:
A specialized sealing material, typically a rubber component, combined with robust metal casings and durable springs, creates a versatile and reliable sealing assembly that meets diverse industrial needs.
Our oil seal options are vast, including types such as: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, ensuring we can meet any specification you require.
Our extensive range of rubber materials for oil seal manufacturing is designed to withstand varying operational conditions. These high-grade, high-performance rubbers endure exposure to a wide spectrum of chemicals and both extreme high and low temperatures, providing unparalleled durability and resilience.
[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.

Achieve superior sealing performance with our customizable non-standard oil seals, crafted from top-tier materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber. Tailored for your specific needs, these materials promise enhanced functionality.

[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 engineering genius creates a protective oil film via contact between the lip and shaft, leveraging spring pressure and the elastic properties of the material to achieve dynamic sealing. As rotation induces heat-driven contraction of the lip, the sealing efficacy is amplified, while stationary periods ensure continued seal integrity.

[Oil seal application fields]
Our oil seals excel in demanding environments, such as engines, gearboxes, hydraulic pumps, and reducers. They shine in high-temperature, high-speed, corrosive conditions, or where traditional seals falter. Notably, PTFE oil seals deliver up to 20 times the longevity of conventional options, effectively sealing water, acids, gases, and other challenging media.

[Oil seal selection and installation]
For optimal performance, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. A careful installation of the vertical shaft, preventing tilting, and application of grease to the lip reduces the risk of dry grinding, ensuring longevity and functionality.
