D65 Sprocket Parts For Bulldozer Undercarriage
After the standard heat treatment of the drive wheel blank of our sprocket, the hardness of the substrate reaches above HB235, and the drive teeth are subjected to medium frequency induction hardening and low temperature tempering. The surface hardness can reach HRC48-54, and the hardening depth is higher than 5-10mm (HRC45). It not only provides accurate power under harsh working conditions, but also has excellent wear resistance and has the effect of extending product life and reducing customer costs.
D65 Carrier Roller Parts For Bulldozer Undercarriage
1. The design of the gap ensures lubrication of the worn surface. 2. Special steel shell not only prevents deformation but also perfectly combines with pressure. 3. A good heat treatment can ensure the depth of hardening and improve wear resistance, while a good support structure prevents deformation. 4. High surface hardness and standard process can guarantee the service life of iron/copper sle.
