Caterpillar D10N Track Drive Sprocket Heat-Treated Undercarriage Part

Sprockets are precision-engineered wheels featuring a unique contour with teeth or cogs designed to interlock seamlessly with chains, tracks, or punctured/recessed materials. These components can be installed at both the leading and trailing ends of a vehicle (or either end individually), and in some mechanisms, an elevated auxiliary sprocket is integrated to actuate the track.

For sprocket manufacturing, materials such as G33MnCrMo5, G33Mn4, SCMnCr4B, ZG40Mn, and ZG35Mn are selected based on model specifications, size, and operational conditions. Through advanced heat treatment, the sprockets achieve HRC48-54 surface hardness with a minimum hardness depth of 5-10mm (HRC45), ensuring exceptional durability under harsh conditions.
