Caterpillar Bulldozer D5K Heat-Treatment Undercarriage Spare Parts for Track Drive Sprocket Segment
1. What Is Sprocket?
Sprockets are core precision-engineered gear wheels featuring a unique tooth profile contour, designed to mesh seamlessly with chains, tracks, or perforated materials via interlocking teeth or cogs. Specifically, they are defined by radial teeth that engage chains during rotation, serving as critical transmission components in tracked and chain-driven systems. Versatile in application, they install at vehicle leading or trailing ends (or both)—and in some setups, a high-position auxiliary sprocket is integrated for track actuation.
Crafted from premium alloys (including G33MnCrMo5, G33Mn4, SCMnCr4B, ZG40Mn, and ZG35Mn) selected based on model specifications, dimensions, and operational demands, sprockets undergo advanced heat treatment to achieve HRC48-54 surface hardness with a 5-10mm hardened depth (HRC45). This ensures extreme durability even in harsh environments like construction and mining, delivering superior wear resistance, a significantly extended service life, and reduced operational costs by cutting down on replacement frequency and operational downtime.
