Product Description

Oil seals, also known as rotary shaft seals, play a critical role in safeguarding mechanical assemblies. These indispensable components effectively seal grease, liquids, or dirt, maintaining the integrity between stationary and mobile parts in various equipment. An oil seal is conventionally comprised of three core elements:
A sealing material (typically a rubber component), metal casings, and springs. This combination results in a highly adaptable sealing assembly.
Our range includes various types like TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse needs.
Our extensive selection of premium rubber materials for oil seal production ensures adaptability to a multitude of operating environments. These advanced materials are engineered to withstand an array of chemicals and endure extreme temperature variations, whether exceedingly high or 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.

For those requiring bespoke solutions, our customizable non-standard oil seals can be crafted using a variety of materials, including fluorine rubber, silicone rubber, fine rubber, and propylene rubber.

[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 forms a protective oil film through the interaction between the lip and shaft, facilitating dynamic sealing with the help of spring pressure and material elasticity. As the assembly rotates, frictional heat causes the lip to contract, intensifying the seal; when stationary, the lip remains in contact to ensure uninterrupted protection.

[Oil seal application fields]
Perfectly suited for use in engines, gearboxes, hydraulic pumps, reducers, and more, these oil seals thrive in high-temperature, high-speed, and corrosive environments, outperforming traditional seals. Notably, PTFE oil seals offer up to 20 times the lifespan of conventional options, adeptly sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
When selecting and installing oil seals, consider the rotation speed, temperature, pressure, and shaft medium characteristics comprehensively. It is crucial to install the vertical shaft correctly to prevent tilting and apply grease to the lip to minimize dry friction and prolong seal life.
