Delve into the fascinating world of oil seals, also known as rotary shaft seals. These indispensable components are expertly designed to maintain the integrity of mechanical assemblies by effectively sealing grease, liquids, and dirt. Playing a crucial role in stabilizing the space between stationary and moving parts, oil seals are vital to ensuring the seamless operation of rotating and moving assemblies. Typically, an oil seal is crafted from three essential elements:
a precision-engineered sealing material (rubber component), robust metal casings, and resilient springs. This versatile assembly ensures a dependable sealing solution for a multitude of applications.
Explore our extensive range of types including: TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, tailored to meet diverse demands.
We proudly offer a wide array of premium rubber materials for the production of oil seals, meticulously selected to guarantee optimal performance under varied operational conditions. Our high-performance materials are crafted to withstand the harshest chemicals and extreme temperatures, be they soaring highs or plummeting lows.
[Discover the exceptional qualities of our oil seal materials]
| 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 |
