E345 Excavator Front Idler Assy for Caterpillar 34.5-Ton Machines

The E345 Idler Assy is a precision-engineered component designed for Caterpillar 34.5-ton excavators. This front idler assembly ensures durability, excellent load-bearing capacity, and smooth operation in demanding construction environments.The E345 idler assy (short for "idler assembly") is a critical wear part in the undercarriage of compact excavators, designed to work in conjunction with track chains to ensure smooth movement, proper track alignment, and efficient power transmission.

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
