The E345 idler is a critical undercarriage component designed to guide the track chain and maintain proper track tension. Built for Caterpillar E345 excavators, it offers excellent durability, stability, and long service life under heavy-duty working conditions.

Product Description
Main features of the products:
The Mitnik E345 Idler is specifically engineered for Caterpillar E345 excavators, commonly used in mining, quarrying, and large-scale earthmoving operations.
Manufactured from high-strength cast steel, the idler body is precision-machined and heat-treated to withstand high impact loads and continuous operation. The robust shaft and bushing system ensures smooth rotation and accurate track guidance, reducing track chain deviation and abnormal wear.
With a reliable sealing structure and reinforced design, the E345 front idler performs consistently in harsh environments such as mud, sand, gravel, and rocky conditions, making it an ideal replacement part for undercarriage repair and maintenance.
