Product Description

Oil seals, also known as rotary shaft seals, play a pivotal role in safeguarding your machinery. These indispensable components ensure that grease, liquids, or contaminants are securely confined, vital for any rotating or moving assembly. By expertly stabilizing the interface between stationary and moving parts, oil seals are fundamental in maintaining the efficiency and longevity of mechanical equipment. Typically, a high-quality oil seal comprises three key elements:
A sophisticated sealing material (primarily a resilient rubber component), reinforced metal casings, and durable springs. Together, they form a versatile and robust sealing assembly designed to meet a wide array of industrial requirements.
Our diverse range of oil seal types includes: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, among others, allowing for precise application across different machinery.
At Ningbo Zhongmu Rubber Products Co., Ltd, we pride ourselves on offering a comprehensive selection of premium rubber materials, meticulously crafted to manufacture superior oil seals. These high-performance materials are engineered to withstand a multitude of chemicals and endure the most extreme temperature variations, ensuring reliability whether in scorching heat 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.

Our customizable non-standard oil seals can be expertly produced using advanced materials such as fluorine rubber, silicone rubber, fine rubber, and propylene rubber, adaptable to your specific 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 oil seal operates by creating a protective oil film through the precise contact between the lip and the shaft, achieving an impeccable dynamic sealing effect. Leveraging the combination of spring pressure and material elasticity, the lip's frictional heat during rotation causes contraction, thus enhancing the seal's efficacy. When stationary, it maintains optimal contact, thereby preserving the integrity of the seal.

[Oil seal application fields]
Our oil seals are universally applied across engines, gearboxes, hydraulic pumps, reducers, and various other industrial equipment. They excel in challenging environments, enduring high temperatures, rapid speeds, and corrosive agents. Notably, our PTFE oil seals outperform traditional variants, lasting up to 20 times longer, and are proficient in sealing media such as water, acid, and gas.

[Oil seal selection and installation]
When selecting and installing an oil seal, consider the rotation speed, temperature, pressure, and medium characteristics of the shaft in detail. Ensure the vertical shaft is installed correctly to prevent tilting, and apply grease liberally to the lip to mitigate dry friction, securing optimal performance and longevity.
