Dingtai manufactures complete undercarriage parts for Mitsubishi bulldozers—track rollers, idlers, sprockets, chains, and shoes—to support and propel the machine.
We operate as a factory-direct supplier, offering full OEM manufacturing services to global distributors and equipment owners with precise specifications.
Our components prevent costly downtime by resisting extreme wear and breakage, even in abrasive rock, sand, and clay environments.
With over 20 years of specialization and ISO9001/SGS certifications, we deliver proven quality that meets strict international standards.
Using 35MnB steel and advanced deep induction quenching, our undercarriage parts achieve a surface hardness of 52–58 HRC for superior longevity.
Core Selling Points

Technical Features
Sealed and lubricated track rollers feature floating face seals that permanently retain oil while blocking dirt, water, and abrasive particles.
Forged link chains made of 35MnB are induction-hardened to a depth of 4–8 mm, creating a wear-resistant case with a tough core.
Precision bushing turning and carburizing minimize internal friction, reducing track pitch elongation and extending the entire undercarriage life.
Applications
These undercarriage parts are deployed in heavy-duty operating conditions: mining overburden removal, quarry rock handling, highway construction, land clearing, and demolition.

Maintenance Guide
Check track sag daily; excessive tension accelerates wear on sprockets and rollers. Adjust as needed to manufacturer spec.
Inspect roller oil levels every 250 hours; low oil indicates seal damage. Replace to prevent internal contamination and failure.
Monitor grouser height; replace shoes when worn to 30% of original height to maintain traction and protect track chain.
Rotate or replace sprocket segments regularly to prevent uneven wear and prolong chain life.
