    1. Our carrier rollers use special steel and produced by new process. Every procedure goes through strict inspection and the property of compressive resistance and tension resistance can be ensured .
    2. The raw material used is national standard 40Mn2 steel. The steel undergoes overall quenching and tempering, as well as intermediate frequency heat treatment.This process ensures that the surface hardness can reach HRC55-60.
    3. The high-standard production and processing load-bearing shaft has excellent mechanical properties against wear, high load, and high rigidity. This greatly prolongs the service life of the assembly.
