Product Description

Product Description

Oil seals, often known as rotary shaft seals, are indispensable in safeguarding machinery by sealing grease, liquids, or dirt. They ensure the integrity of rotating and moving components by maintaining the critical space between stationary and mobile elements in mechanical systems. A comprehensive oil seal typically comprises three core elements:
This includes a sealing material (the rubber component), metal casings, and springs, forming a versatile sealing solution adaptable to various needs.
We offer a plethora of types, including TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among numerous others, catering to diverse sealing requirements.
Our extensive range of rubber materials for oil seal manufacturing is designed to meet various operational demands, offering exceptional resistance to a broad spectrum of chemicals and 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.

We specialize in crafting customizable non-standard oil seals. Materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber are employed to meet specific client 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 dynamic sealing efficacy of an oil seal is achieved by the interaction between the lip and the shaft, forming an oil film. This is enhanced by spring pressure and material elasticity. Rotational movement generates frictional heat, contracting the lip for improved sealing, while stationary contact maintains the seal.

[Oil seal application fields]
Our oil seals find extensive application in engines, gearboxes, hydraulic pumps, reducers, and more, thriving in high temperatures, high speeds, and corrosive environments. PTFE oil seals, in particular, offer unparalleled longevity—lasting up to 20 times longer—capable of sealing water, acids, gases, and other challenging media.

[Oil seal selection and installation]
Consider shaft rotation speed, temperature fluctuations, pressure dynamics, and medium characteristics for optimal oil seal selection and installation. Ensure vertical shaft alignment to prevent tilting, and apply grease to the lip to minimize dry grinding.
