Core Information

Function: Guides the track to rotate correctly, works with the tensioning device to adjust track tension, reduces the risk of track deviation and derailment, while supporting part of the equipment's weight.

Features: Manufactured from high-strength cast steel with wear-resistant surface treatment. The flange is designed with a curved profile to conform to the track guide rail. Incorporates sliding bearings or roller bearings for high load capacity and impact resistance. Sealed construction prevents mud and sand ingress.

Compatible Models: Primarily SD22/SD32, D85/D155 bulldozers, also suitable for similarly sized track Loaders and scrapers.

Guide wheels are typically mounted at the front end of the machine's undercarriage, forming part of the track's support and drive system alongside drive sprockets, idler wheels, and track rollers. Routine maintenance requires regular inspection of guide wheel wear and track tension. Excessive wear accelerates track deterioration and increases travel resistance.
