Product Description

Oil seals, also known as rotary shaft seals, are pivotal for maintaining the integrity of moving assemblies. They expertly seal grease, liquids, or debris, ensuring seamless operation across mechanical equipment. By stabilizing the interface between stationary and dynamic components, they become indispensable in the machinery ecosystem. Typically, each oil seal is engineered with three critical elements:
a resilient sealing material (rubber component), robust metal casings, and precisely calibrated springs. Together, these elements form a versatile sealing assembly, adept at adapting to a multitude of applications.
Our comprehensive range includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among many others, each tailored for specific operational needs.
We proudly offer a wide array of premium rubber materials for crafting oil seals, ensuring unmatched performance across various operational environments. These materials are engineered to withstand a spectrum of chemicals and extreme temperatures, both high and low, providing durable and dependable sealing solutions.
[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 are crafted from materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, allowing for bespoke solutions to meet unique operational demands.

[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 operates by forming an oil film through the interaction of the lip and shaft. This dynamic sealing is achieved via the synergy of spring pressure and material elasticity. During rotation, frictional heat induces lip contraction, enhancing the sealing efficacy; when stationary, it maintains contact, ensuring uninterrupted sealing.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more. They excel in high-temperature, high-speed, and corrosive environments, where conventional seals fall short. For instance, PTFE oil seals can outlast traditional counterparts by up to 20 times, proficiently sealing water, acid, gas, and other challenging media.

[Oil seal selection and installation]
A holistic approach to selection includes considering shaft characteristics like rotation speed, temperature, pressure, and medium. Proper installation is crucial: ensure vertical shaft alignment to prevent tilting and apply grease to the lip to minimize dry friction and prolong seal life.
