Product Description

Oil seals, often known as rotary shaft seals, play a pivotal role in mechanical assemblies by securely sealing grease, liquids, and dirt. These indispensable components stabilize the gap between stationary and moving parts, ensuring seamless function. Each oil seal is crafted with three essential elements:
A robust sealing material (rubber component), durable metal casings, and reliable springs, making it a highly adaptable sealing assembly.
Our array of types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among a wide selection.
At Ningbo Zhongmu Rubber Products Co., Ltd, we offer an extensive range of rubber materials for oil seals, catering to diverse operational conditions. Our high-performance materials withstand challenging chemicals and extreme temperatures, ensuring durability and reliability.
[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.

Tailor-made non-standard oil seals are expertly crafted from premium materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, offering versatility and resilience.

[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 cutting-edge design of our oil seals features an oil film formed through the dynamic interaction of the lip and shaft, utilizing spring pressure and elasticity for enhanced sealing. As the shaft rotates, frictional heat causes the lip to contract, optimizing the seal; while stationary, it maintains its grip to prevent leakage.

[Oil seal application fields]
Favored in various sectors, including engines, gearboxes, hydraulic pumps, and reducers, our oil seals excel in high-temperature, high-speed, and corrosive environments. Notably, PTFE oil seals surpass traditional options, offering up to 20 times more longevity and the capability to effectively seal water, acid, gas, and more.

[Oil seal selection and installation]
Careful consideration of shaft rotation speed, temperature, pressure, and medium properties is crucial. Ensure vertical installation to avoid misalignment and use grease on the lip to minimize dry friction.
