Why YSM Forged D155 Bottom Rollers Outperform Standard Alternatives

  • Precision Brand Compatibility: Engineered specifically for the heavy-duty demands of D155 bulldozer models. Dimensions, tolerances, and seals perfectly match Komatsu and Shantui undercarriage systems for a seamless swap-out.
  • Superior 40Mn2 Forging Quality: Unlike common cast iron rollers that fracture under extreme load, our 40Mn2 forged steel body provides the essential internal density required for high-impact rock and earthmoving projects.
  • Flawless Japanese Friction Welding: Utilizing imported machinery from Japan, the friction welding joints on our lower roller assemblies guarantee flawless structural integrity, eliminating the risk of oil seals breaking mid-operation.
  • Trusted Global OEM Quality: With a robust track record executing contract manufacturing for major global aftermarket brands like ITR, YSM guarantees international wholesalers the highest tier of manufacturing reliability directly from China.
