Komatsu DH55 Excavator Sprocket Undercarriage Track Parts Standard Dimension

The DH55 Sprocket is a precision-engineered component designed for excavators in demanding projects. This vital wear part in the undercarriage system of Komatsu DH55 excavators ensures durability, excellent load-bearing capacity, and smooth operation in compact construction machinery.

The DH55 Sprocket works in conjunction with track chains, idlers, and rollers to guide the track chain along its correct path, reduce friction between moving components, and support the excavator's weight during tasks like digging, pushing, and traversing rough terrain. Proper maintenance is essential to minimize downtime and extend the undercarriage lifespan.

Our production involves rigorous quality-controlled processes:

• High-grade Material Selection: Components are crafted from premium materials for maximum durability
• Outer Race/Shell: High-carbon chromium bearing steel (SUJ2) for superior hardness and wear resistance
• Inner Roller/Spindle: Alloy steel (SCM440) engineered to withstand significant radial and axial loads
• Seals & Lubrication: Nitrile rubber (NBR) seals for oil resistance with lithium-based grease for long-term lubrication
• Quality Assurance: All materials undergo thorough inspection for chemical composition and mechanical properties using spectrometers and hardness testers
