Oil seals, often known as rotary shaft seals, serve as critical guardians against the intrusion of grease, liquids, or dirt. Essential for any dynamic assembly, they deftly bridge the gap between stationary and moving components within mechanical systems. At the heart of these seals are three integral elements, working in harmony to ensure seamless operation.
Crafted from premium sealing materials, typically rubber, these components are reinforced with sturdy metal casings and resilient springs. Their versatile design makes them indispensable in various applications.
Our extensive range includes types such as TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and the advanced TC4, catering to a myriad of operational needs.
Explore our comprehensive selection of rubber materials engineered for durability and excellence. Specifically formulated, these high-performance rubbers withstand harsh chemicals and drastic temperature fluctuations, both high and low, ensuring reliability across diverse conditions.
[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 for optimal performance. Ensure the vertical alignment of the shaft to avoid tilting and generously apply grease to the lip to mitigate dry grinding.
