All GEE ESS Sugar Chain wheels are now manufactured from carbon steel plate En8 (equates to the analysis of SAE 1040).
Very accurate profiles are assured by magic eye guided flame cutters. Mild steel bosses are made to suit shaft size used a avoid unnecessary weight and are argon arc welded both sides to full depth plate to complete the fabrication.
The assembly is then furnace normalized to remove stresses set up in manufacture. Teeth sides above the PCD are chamfered to ensure easy entry between sidebars. After this process, the teeth surfaces can be flame hardened to resist wear in every arduous condition but in roller chain applications we find this is rarely required.
