Oil seals, often recognized as rotary shaft seals, serve as the unsung heroes of mechanical assemblies, playing a crucial role in safeguarding systems by sealing in grease, liquids, or excluding dirt. An indispensable component for any rotating and moving setup, oil seals ensure harmony between stationary and dynamic parts, cementing their importance in mechanical equipment. These seals are typically crafted from three key elements, forming a robust barrier against unwanted leaks.
The essential components of an oil seal include a resilient sealing material comprising a specialized rubber component, durable metal casings, and robust springs, making it an exceptionally adaptable sealing solution. This trifecta works in unison to provide reliable sealing performance across a multitude of applications.
We proudly offer a comprehensive array of oil seal types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others. Each type caters to a specific application, ensuring that whatever your sealing needs may be, we have the right solution to meet your requirements.
Our product line features a wide variety of superior rubber materials crafted specifically for oil seal manufacturing, guaranteeing optimal performance under diverse operating conditions. These premium rubber compositions are engineered to withstand an extensive range of chemicals and endure extreme temperatures, from scalding to freezing, without compromising on efficiency.
[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 |
