Caterpillar D68EX Bulldozer Heat-Treatment and Heavy Duty Undercarriage Spare Parts for Track
Drive Sprocket with OEM Quality
1. What Is Sprocket?
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. These versatile components can be installed
at either the leading or trailing ends of a vehicle—or both—and in certain mechanisms, a high-position auxiliary sprocket is integrated to drive the track motion.
For manufacturing, sprockets are crafted from premium alloys such
as G33MnCrMo5, G33Mn4, SCMnCr4B, ZG40Mn, and ZG35Mn, carefully selected based on model requirements, dimensions, and operational conditions. Through advanced heat treatment processes, they achieve HRC48-54 surface hardness with a minimum hardened layer depth of 5-10mm (HRC45), ensuring extreme durability even in harsh environments. This results in superior wear resistance and a significantly extended service life, directly reducing our customers’ operational costs by minimizing replacement frequency and downtime.
