Core Information

Function: Supports the upper portion of the track, reducing sag and vibration during operation to maintain proper tension and prevent friction with the frame. Simultaneously guides the track for smooth rotation, minimizing wear and noise in the travel system.

Features: Manufactured from high-strength cast steel with surface hardening for wear resistance; dual-flange design ensures precise alignment with track guides; integrated sealed bearings prevent mud ingress, suitable for harsh environments like mines and muddy terrain.

The idler wheel is mounted above the track, with its wear rate closely linked to track tension. Routine maintenance requires periodic inspection of the idler wheel's surface wear and bearing seal integrity. Excessive wear increases the risk of track sagging and derailment, while seal failure can cause bearing seizure, abnormal noise, and other malfunctions.
