Product Description
DH220 DH220-7 DH370-7 Excavator Sprocket Undercarriage Parts
for Construction Machinery
1. What Is sprocket ?
It plays the role of driving the track, is fixed on the walking motor, and transmits the driving force of the walking motor to the track through the gear structure. tongThere is usually 1 on each walking motor.

2. Advantages / Features
The blank of the driving wheel made of materials such as SCMnCr4B, ZG40Mn, and ZG35Mn is heat-treated by normalizing, with the base hardness reaching HB235 or above. The driving teeth are heat-treated by a full-circle medium-frequency induction quenching and low-temperature tempering process, with the surface hardness reaching HRC48-54 and the hardening depth exceeding 5-10mm (HRC45). Even under harsh working conditions, this driving wheel can ensure the precision of power transmission and exhibit outstanding wear resistance, thus significantly extending the service life of the product and lowering the customer's usage cost.
