Product Description
EX200 Bulldozer Front IdlerFor Bulldozer Construction parts
1. What Is front idler ?
The Idler is fundamental for maintaining uninterrupted chain motion and correcting misalignment. It also absorbs a portion of the load, reinforcing connection points and reducing earth pressure from these mechanisms. Positioned at the core, a support beam holds each chain segment, allowing bidirectional guidance. A small separation between the Idler and the rotating part improves alignment and directional accuracy, ensuring dependable and efficient operation.

2. Advantages / Features
High Quality
The material is treated with normalization for better performance, and the rail's outer surface is hardened via medium-frequency induction, achieving a hardness range of HRC48 to HRC58, with a minimum hardened zone depth of 4-6mm (attaining HRC45 at this precise measurement).
High Precision
The guide wheel incorporates a unique design, is subjected to precise thermal processing for increased robustness, and withstands shocks, featuring a toughened surface with a deeply hardened zone, extending service duration and maintaining track steadiness. High-performance sealing components enhance reliability, ensuring smooth and consistent functionality.
