Komatsu D475 Undercarriage Spare Parts - Bottom Single Flange/Double Flange Heavy Duty Track Roller 198-30-00544/198-30-00653


1. What is a track roller?

Track rollers form the bulldozer’s frontline defense: carrying its full weight, enduring punishing ground impacts, and producing over 70% of operational resistance. To ensure battlefield-grade reliability, every unit is subjected to rigorous 0.6 MPa (6 bar) gas pressure testing – a benchmark 60% stricter than industry requirements. This proactive leak prevention at the source yields assemblies proven for >3,000 operational hours, unfazed by perpetual immersion in mud/sand abrasives.
