Restoration of the dimensions of the outer diameter wear area.

We perform restoration and repair related to railways. We can restore and regenerate worn or damaged parts and restore dimensions, allowing us to regenerate expensive components without discarding them.

This is an introduction to the research and development conducted by Kōei Techno System Co., Ltd., aimed at enhancing the quality of parts, improving wear resistance, heat resistance, and corrosion resistance, similar to preventive healthcare, with a focus on the repair, regeneration, extension of life, and maintenance of components. Regenerated parts reduce CO2 emissions compared to manufacturing new parts, making them suitable for environmental conservation. Our main techniques include thermal spraying, welding, and machining. 【Dimension Restoration of Outer Diameter】 Restoration of wear on oil seal areas ● Build-up thermal spraying (13Cr stainless steel) ⇒ Photo 1 ● Grinding ⇒ Photo 2 ● After finishing processing ⇒ Photo 3 【Processing Examples】 Dimension restoration of various electronic shaft bearing areas with reduced thickness ● Restoration of wear on bearing areas ⇒ Photo 4 ● Restoration of wear on bearing and coupling areas ⇒ Photo 5, ⇒ Photo 6 【Processing Examples】 Dimension restoration of various construction reduced thickness areas ● Various shafts: Restoration of wear on oil seal and bush areas ⇒ Photo 7 ● Flange ⇒ Photo 8 ● Taper sealing rod: Restoration of wear on oil seal area ⇒ Photo 9 【Cross-sectional Structure of Thermal Sprayed Coating】 ● Cross-sectional structure of thermal sprayed coating ⇒ Photo 10
