Modern construction, mining and agricultural operations are shifting toward high-intensity, round-the-clock operation, placing stringent requirements on the durability and stable performance of core machinery parts. Harsh working environments including heavy dust, mud and variable temperatures easily cause component wear and equipment failure, making high-quality sealing technology the key barrier to safeguarding continuous machine operation.
Persistent operational wear, frequent equipment downtime and insufficient high-end spare part supply have long plagued the global construction, mining and agricultural machinery sectors. As industrial equipment operates under harsher working conditions and higher load intensities worldwide, durable, precision-engineered sealing components have become a core determinant of machinery stability and service life.
(1) Precision casting type
This type of sealing ring is mostly made of high-chromium molybdenum alloy cast iron and is precision cast using paraffin shell molds. The hardness of the blank is (40-50) hrc, and the surface hardness of the finished product can reach (65-72) hrc. The roughness of the working surface is R, which ranges from 0.2 to 0.4um. Normally, the R value is 0.1. um, the service life can reach 4000~6000 hours. There are many manufacturing processes for this material, and many manufacturers use this method.
(2) Mechanical die-casting mold
This type of floating seal ring is made of alloy cast iron and is die-cast. The finished metallographic structure is relatively fine. However, the cost is slightly higher. The roughness R value of the working surface is 0.2-0.4um. The R value of the bright band is 0.09~0.15um. The service life is About 4000~6000h.
(3) Powder metallurgy hot satin type
This kind of sealing ring is mostly made of powder metallurgy through high-temperature hot forging. The working surface roughness R value is generally 0.4um, the finished product surface hardness (40~62) hrc, and the service life is about 2000~4000 hours.
(4) Thermal spray type.
The base body of the sealing ring is ordinary cast iron. It is thermally sprayed with 0.05~0.20mm high chromium molybdenum powder on the working surface and then grinded. The surface hardness reaches (55~65) hrc, and the service life can reach 4000~6000 hours. This type of process saves rare metals, but it is subject to equipment constraints, low productivity and high cost.
