Product Description
E312/200B/320/330/325/330 Excavator Sprocket Undercarriage Parts
for Construction Machinery
1. What Is sprocket ?
The excavator sprocket of an excavator constitutes a vital part of its propulsion system, serving an indispensable function. Its fundamental roles span four pivotal areas: the efficient conveyance of mechanical power, the provision of sturdy structural support and traction to guarantee smooth operation, the augmentation of operational stability and resistance to seismic forces, and ultimately, the direct influence it wields on work efficiency and production output.

2. Advantages / Features
The materials for the driving wheel can be selected based on the machine size and mining application, including options such as G33MnCrMo5, G33Mn4, SCMnCr4B, ZG40Mn, and ZG35Mn. After being normalized, the base hardness of the driving wheel blank reaches above HB235. The driving teeth, after being induction hardened around the entire circumference and tempered at low temperature, achieve a surface hardness of HRC48-54, with a hardening depth of 5-10mm (HRC45) or more. This ensures precise power transmission even in harsh working conditions and provides excellent wear resistance, significantly extending the product's service life and reducing customer operating costs.
