Product Description

Oil seals, often known as rotary shaft seals, serve a crucial role in sealing grease, liquids, or dirt, ensuring the flawless operation of mechanical assemblies. As indispensable elements in any rotating and moving setup, they effectively stabilize the interplay between stationary and mobile components within the machinery. An oil seal typically comprises three vital components:
The robust and versatile sealing assembly includes a sealing material (rubber component), metal casings, and supportive springs.
We offer a comprehensive array of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4.
Our diverse selection of rubber materials for crafting oil seals guarantees adaptability across various operational scenarios. These high-performance rubbers withstand a broad spectrum of chemicals and extreme temperatures, 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.

Tailored non-standard oil seals can be crafted from top-grade materials like fluorine rubber, silicone rubber, fine rubber, and propylene rubber, meeting diverse industrial needs.

[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 ingenious design of the oil seal forms an effective oil film via lip and shaft contact, achieving superior dynamic sealing through the synergy of spring pressure and material elasticity. During rotation, the lip contracts from frictional heat, enhancing the seal's integrity; while stationary, it maintains essential contact to ensure sealing efficacy.

[Oil seal application fields]
Our oil seals are extensively utilized across engines, gearboxes, hydraulic pumps, reducers, and other critical equipment. They excel in high-temperature, high-speed, and corrosive environments where traditional rubber seals falter. Notably, PTFE oil seals outlast conventional versions by up to 20 times, sealing water, acid, gas, and varied media with precision.

[Oil seal selection and installation]
Considerations for optimal selection include shaft rotation speed, temperature, pressure, and medium properties. For installation, ensure vertical shaft placement to avoid tilting and apply grease to the lip to prevent dry grinding, enhancing durability.
