Oil seals, often identified as rotary shaft seals, play a pivotal role in safeguarding mechanical systems. These indispensable components are expertly designed to keep grease, liquids, and dirt at bay, thus preserving the integrity of rotating and moving assemblies. By stabilizing the crucial interface between stationary and moving parts in mechanical equipment, the oil seal ensures seamless operation. Typically, it is crafted from three essential elements:
First, a robust sealing material comprising a specialized rubber component; second, durable metal casings; and third, resilient springs. Together, these elements form a versatile and reliable sealing assembly.
Oil seals come in a variety of types to suit different applications, including the popular TC, TG, TA, SA, SB, SC, DC, MC, MG, TCV, TCN, and TC4, among others, offering broad adaptability.
We take pride in offering an extensive array of sophisticated rubber materials for crafting oil seals, ensuring their suitability across a myriad of operating conditions. These high-performance materials are engineered to withstand a wide spectrum of chemicals and endure the rigors of extreme temperatures, from scorching heat to frigid cold.
[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 |
