Advantages of VM® Hitachi Sumitomo Upper Roller:
The VM® manufacturing advantage is clear in our SCX300 top rollers. We use a specialized integrated quenching heat treatment that hardens the entire roller body uniformly, preventing the formation of weak spots. Every unit undergoes rigorous dimensional checks to guarantee a perfect fit with the machine’s track chain and frame, ensuring seamless integration with other undercarriage parts like idlers..
Testing of VM® Hitachi Sumitomo SCX300 Top Roller
Quality is paramount. Every VM® top roller for the SCX300 is subjected to a strict testing protocol. This includes rotational tests under load to verify smooth bearing operation, pressure testing of the sealing system to prevent future leaks, and hardness tests across the surface to confirm uniform treatment.
