KOMATSU 144-81-30054 Top Roller D65A-8 Carrier Roller

Enhance the efficiency and reliability of your bulldozer with our carrier rollers.The carrier rollers function are to convey the weight of bulldozer to the ground,and also to limit the track to prevent sideslip.The Carrier Roller force the track to slip on the ground when machine turns.Good working and wear-resistance are important.

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.
