Product Description

Oil seals, also known as rotary shaft seals, are indispensable in safeguarding against the intrusion of grease, liquids, or dirt. These vital components play a crucial role in stabilizing the space between both stationary and mobile parts within mechanical equipment, ensuring seamless operation. Essential to any rotating assembly, an oil seal typically embodies three core elements:
Comprising a sealing material (rubber component), robust metal casings, and resilient springs, this versatile sealing assembly assures an effective barrier against unwanted substances.
Our diverse array of types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, catering to various needs.
We proudly offer an extensive selection of premium rubber materials for crafting oil seals, perfectly suited to endure diverse operating conditions. These materials are designed to withstand a plethora of chemicals and extreme temperatures, whether scorching hot or freezing cold.
[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.

Custom-designed non-standard oil seals can be crafted from exceptional materials, including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, tailored to your specific 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 ingenious principle involves the creation of an oil film through the delicate contact between the lip and the shaft, achieving dynamic sealing by leveraging spring force and material elasticity. During rotation, the lip contracts from frictional heat, enhancing the seal; while stationary, it maintains contact to preserve integrity.

[Oil seal application fields]
Our oil seals are extensively applied in engines, gearboxes, hydraulic pumps, reducers, and other critical equipment. They excel in high-temperature, high-speed, and corrosive environments, overcoming the limitations of traditional rubber oil seals. For instance, PTFE oil seals offer longevity up to 20 times greater than conventional seals and effectively seal water, acid, gas, and more.

[Oil seal selection and installation]
Consider rotation speed, temperature, pressure, and medium characteristics comprehensively. Ensure precision by installing the vertical shaft correctly to avoid tilting and apply grease to the lip to reduce friction and enhance longevity.
