Oil seals, often known as rotary shaft seals, play a crucial role in modern mechanical assemblies. Their primary function is to effectively seal grease, liquids, or dirt, preventing contaminants from compromising the functionality of your machinery. As a vital component, oil seals bridge the gap between stationary and moving parts, ensuring smooth and efficient operations across diverse mechanical equipment. Each oil seal is crafted with precision and comprises three key elements:
The fundamental architecture of an oil seal showcases a harmonious blend of a sealing material (rubber component), robust metal casings, and resilient springs. This versatile assembly is designed to tackle various sealing challenges with exceptional endurance and adaptability.
Our range includes an extensive variety of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the innovative TC4, among others, catering to diverse application needs.
Ningbo Zhongmu Rubber Products Co., Ltd takes pride in offering an extensive selection of premium rubber materials for oil seal manufacturing. Our materials are engineered to meet the demands of various challenging operating conditions, withstanding a spectrum of chemicals and extreme temperature fluctuations, whether in high-heat or freezing environments.
[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. |
| 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) |
| 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 |
