Product Description

Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in machinery by effectively sealing grease, liquids, or dirt. As a vital component of any rotating and moving assembly, they ensure the stabilization of the space between stationary and moving parts within mechanical equipment, enhancing operational efficiency and longevity. An oil seal typically encompasses three primary elements:
These elements include a sealing material (often a rubber component), robust metal casings, and supportive springs, forming a versatile and highly effective sealing assembly.
Our comprehensive range of oil seal types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to a wide array of industrial requirements.
We deliver an extensive variety of rubber materials for oil seal production, tailored to meet diverse operational conditions. These high-performance materials withstand a broad spectrum of chemicals and extreme temperature variations, ensuring reliability and durability in both high and low thermal environments.
[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.

Our customizable non-standard oil seals can be crafted from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, meeting specific client requirements.

[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 ingeniously creates an oil film through the contact between its lip and the shaft. This dynamic sealing is achieved by leveraging the combined forces of spring pressure and material elasticity. Upon rotation, the lip contracts due to frictional heat, enhancing the seal; when at rest, it maintains contact to sustain the seal integrity.

[Oil seal application fields]
Our oil seals are widely implemented in engines, gearboxes, hydraulic pumps, reducers, and various other equipment. They excel in high-temperature, high-speed, and corrosive environments where traditional seals falter. For example, PTFE oil seals offer up to 20 times the durability of standard oil seals, capable of effectively sealing diverse media such as water, acids, and gases.

[Oil seal selection and installation]
When selecting an oil seal, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical installation to avoid tilting, and apply grease to the lip to minimize dry grinding, optimizing performance and longevity.
