VOLVO EC200 Excavator Track Drive Sprocket HRC52-58 Heat-Treated

Sprockets are precision-engineered gear wheels featuring a unique tooth profile contour, designed to mesh seamlessly with chains, tracks, or perforated materials through interlocking teeth or cogs. Specifically, the term refers to wheels with radial teeth that engage with a chain during rotation, serving as critical transmission components in tracked or chain-driven systems.

For manufacturing, sprockets are crafted from premium alloys such as G33MnCrMo5, G33Mn4, SCMnCr4B, ZG40Mn, and ZG35Mn, selected based on model specs, size, and operational demands. Through advanced heat treatment, they achieve HRC48-54 surface hardness with a minimum hardened layer depth of 5-10mm (HRC45), ensuring extreme durability in harsh environments like construction or mining.
