Oil seals, often known as rotary shaft seals, are indispensable in preventing the ingress of grease, liquids, or dirt. These seals play a crucial role by bridging the space between moving and stationary parts in mechanical equipment, maintaining stability and efficiency. Typically, an oil seal is crafted from these three core elements:
A sealing material (rubber component), metal casings, and springs make up this highly adaptable sealing assembly.
Our product range includes various types: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, TC4, and more, catering to diverse needs.
We provide an extensive variety of rubber materials to manufacture oil seals, tailored to suit a broad range of operational conditions. These premium rubber materials are engineered to withstand extreme chemical exposures and drastic temperature variations, be it high or low, ensuring durability and reliability.
[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 |
When installing, consider the shaft's rotation speed, temperature, pressure, and medium characteristics to ensure optimal performance. It is crucial to install the vertical shaft precisely to avoid tilting and to apply grease to the lip to minimize dry grinding.
