HITACHI Mini Excavator EX30 Undercarriage Spare Parts Professional Quench-Tempering Sprockets with High Guarantee

1. What Is Sprocket?

* A sprocket is a contoured wheel with teeth or cogs that interlock with a chain, track, or other perforated/notched components. The term “sprocket” broadly refers to any wheel with radial projections designed to engage with a chain traveling over it.

* Sprockets can be mounted on either the front or rear of a vehicle—sometimes both. In specific configurations, an additional elevated sprocket may also be included to power the track.

* Sprockets are crafted using materials such as G33MnCrMo5, G33Mn4, SCMnCr4B, ZG40Mn, and ZG35Mn—selections tailored to the specific model, size, and operating conditions. After undergoing precision heat treatment, these sprockets achieve a surface hardness of HRC 48–56, with a minimum hardened layer depth of 5–10mm (maintaining HRC 45 at the layer core). This engineering ensures they thrive in harsh operating environments, boasting long-lasting wear resistance and significantly extended service life—ultimately lowering our customers’ operational costs.
