Product Description

Oil seals, also known as rotary shaft seals, are pivotal in safeguarding mechanical systems by sealing grease, liquids, or dirt, thus preserving the harmony between stationary and moving components. These seals are indispensable in rotating assemblies, as they meticulously stabilize the space between the parts. An oil seal primarily comprises three essential constituents:
1. A sealing material, often a rubber component, 2. Robust metal casings, and 3. Resilient springs. This combination delivers a highly adaptable sealing assembly suitable for various applications.
The range of types available is extensive, including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, catering to diverse sealing needs.
Ningbo Zhongmu Rubber Products Co., Ltd proudly offers an extensive array of rubber materials tailored for oil seal manufacturing. Our materials are engineered to thrive under a spectrum of operating conditions, showcasing resilience against various chemicals and withstanding extreme temperatures, whether scorching or freezing.
[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 ability to produce customizable non-standard oil seals is unparalleled. We utilize premium materials, including fluorine rubber, silicone rubber, fine rubber, and propylene rubber, to meet specific client 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 sealing prowess of our oil seal lies in its ability to create an oil film through the delicate interaction between the lip and the shaft. This dynamic sealing process harnesses spring pressure and material flexibility. Upon rotation, the lip contracts due to friction-induced heat, enhancing the seal's efficacy; when still, it remains intact to ensure continuous sealing.

[Oil seal application fields]
Our oil seals are extensively employed across a multitude of applications, such as engines, gearboxes, hydraulic pumps, and reducers. Designed for high temperatures, rapid speeds, and corrosive environments, they excel where traditional seals falter. Notably, PTFE oil seals deliver remarkable longevity, enduring up to 20 times longer than conventional counterparts, sealing water, acid, gas, and more.

[Oil seal selection and installation]
The meticulous selection of oil seals demands a comprehensive assessment of shaft rotation speed, temperature, pressure, and medium characteristics. To ensure flawless installation, maintain a vertical shaft alignment and apply grease to the lip, minimizing dry grinding and enhancing longevity.
