Oil seals, often known as rotary shaft seals, play a vital role in safeguarding mechanical assemblies. They ensure the seamless containment of grease, liquids, or dirt, serving as a cornerstone in the stability of rotating systems. By effectively bridging the gap between stationary and dynamic components of machinery, oil seals maintain optimal function and longevity. Typically, these indispensable seals are crafted with three core elements:
A robust sealing material (rubber component), durable metal casings, and reliable springs form the essential framework of this versatile sealing assembly, ensuring efficiency across a multitude of applications.
We provide a wide array of types, including but not limited to: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, meeting diverse industrial needs.
Our extensive range of rubber materials guarantees the manufacturing of oil seals that are tailored for various operational contexts. These premium materials are engineered to withstand a spectrum of chemical exposures and endure both high and low extreme temperatures, thereby ensuring reliability and performance.
[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 |
