Oil seals, also known as rotary shaft seals, are indispensable in safeguarding mechanical systems. These dynamic components excel at sealing grease, liquids, or dirt, making them an essential element in ensuring the efficiency of rotating and moving assemblies. By maintaining a stable barrier between stationary and moving parts, oil seals enhance the reliability and longevity of mechanical equipment. Typically, an oil seal is engineered from three pivotal components:
The sealing element, crafted from durable rubber, robust metal casings, and resilient springs. This versatile assembly ensures optimal performance and adaptability across various applications.
Our diverse range of types includes TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, providing solutions for all sealing needs.
Our expansive selection of premium rubber materials is tailored for oil seals, guaranteeing optimal performance under diverse operating conditions. These top-tier rubber formulations are adept at withstanding a wide array of chemicals and extreme temperatures, whether scorching or freezing.
[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 |
For successful installation, consider the shaft's rotation speed, temperature, pressure, and medium characteristics. Ensure vertical alignment to prevent tilting, and generously apply grease to the lip area to minimize dry friction and maximize seal efficiency.
