Undercarriage Parts

Under this category, BOLTRAC undercarriage parts provide reliable support and smooth mobility for construction machinery such as excavators, bulldozers, crawler loaders, and track-type tractors. As the foundation of your equipment, the undercarriage system bears the machine's weight while delivering stable traction and shock absorption across uneven terrains. Manufactured from high-strength alloy steel with advanced heat treatment processes, BOLTRAC components maximize wear resistance and structural integrity. The product lineup includes precision-assembled track chains with bushings; track shoes available in various widths and patterns; carrier rollers and track rollers engineered for long service life; sprockets for precise drive engagement; and front and rear idlers for proper track tensioning and guidance.
