Oil seals, often recognized as rotary shaft seals, are indispensable components in mechanical assemblies. These seals play a crucial role in preventing the leakage of grease, liquids, or dirt, thereby maintaining the integrity of rotating and moving assemblies. By bridging the space between stationary and dynamic parts, oil seals ensure the smooth operation and longevity of machinery. Typically, a standard oil seal comprises three main elements:
A sealing material, typically a robust rubber component, metal casings for structural support, and springs for maintaining the needed tension. This amalgamation creates a highly adaptable sealing solution.
Our range includes a variety of types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the versatile TC4, alongside many others.
At Ningbo Zhongmu Rubber Products Co., Ltd, we offer an extensive selection of rubber materials tailored for oil seal production. Our high-quality materials are engineered to withstand diverse operational conditions, including exposure to various chemicals and extreme temperature variations, ensuring reliability in both high and low-temperature 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 |
