Oil seals, often recognized as rotary shaft seals, play a pivotal role in safeguarding mechanical integrity by effectively sealing grease, liquids, or dirt. These indispensable components are crucial in any rotating and moving assembly, ensuring the seamless operation of mechanical equipment by stabilizing the interface between stationary and dynamic parts. An oil seal typically comprises three integral elements that work harmoniously to maintain perfect sealing effectiveness.
The fundamental components of an oil seal include a resilient sealing material made from high-grade rubber, robust metal casings for structural support, and durable springs for consistent tension. This versatile sealing assembly is engineered for exceptional performance, offering reliability and adaptability across varied applications.
Our comprehensive range of oil seal types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, catering to diverse sealing requirements with precision and effectiveness.
We provide an extensive array of premium rubber materials for manufacturing oil seals, ensuring optimal performance in a variety of challenging operating conditions. Our high-performance rubbers are engineered to withstand exposure to a broad spectrum of chemicals and endure extreme temperatures, whether they are soaring highs or freezing lows.
[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 |
