DX260 Excavator Front Idler Assy for Doosan 26-Ton Models

The ​​DX260 Idler Assy​​ (short for "idler assembly") is a critical undercarriage component designed for ​​Daewoo DX260 excavators​​, serving to guide and tension the tracks while supporting the machine’s weight. Regular replacement of worn idler assemblies is essential to maintain track alignment, prevent slippage, and extend the lifespan of the entire undercarriage system.

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
