Fit Machine: Komatsu D85 Heavy Crawler Bulldozer
This sprocket segment (track segment) is a heavy-duty aftermarket replacement undercarriage wear part for Komatsu D85 engineering bulldozers. Manufactured from high-strength alloy steel with full-tooth carburizing deep quenching heat treatment, it meshes smoothly with matched track chains and delivers stable driving power under heavy-load working conditions such as earthmoving, stone quarries and open-pit mines.
Core Advantages

Deep Hardened Drive Teeth
Ultra-high hardness tooth surface features outstanding wear resistance, significantly extending service life on rocky and muddy mine construction sites.
High Toughness Steel Body
Effectively resists cracking and permanent deformation during long-duration full-load pushing operations of heavy bulldozers.
Precision CNC Machining Tooth Profile
Enables seamless meshing with track links to lower track abrasion and efficiently avoid track jumping and derailment.
