Dingtai manufactures replacement Sumitomo track shoes. Each shoe bolts to the track chain, transfers machine weight, and provides traction in demanding undercarriage applications.
We provide factory-direct OEM manufacturing services. Global clients receive machined, heat-treated track shoes built from verified drawings and material specifications.
Our track shoes solve premature wear and breakage. Controlled hardness and precision bolt holes reduce downtime and prevent track chain misalignment on job sites.
With over 20 years of engineering experience, Dingtai operates under ISO9001 quality systems. SGS material reports verify every production batch.
We forge from 35MnB steel and apply deep induction quenching. This produces a wear-resistant surface and a tough core for high-impact undercarriage loads.

Technical Features
Each Sumitomo track shoe uses precision-forged 35MnB steel. Induction hardening creates a wear-resistant surface while preserving core toughness for impact loads.
CNC-machined bolt holes and contact faces ensure accurate fit with OEM track chains. Correct pitch alignment reduces uneven wear and extends undercarriage life.
Available grouser profiles—single, double, and triple grouser—match traction requirements and machine weight distribution in demanding terrain.
Applications
- Mining and quarry loading
- Heavy civil construction
- Road building and grading
- Demolition and material handling
- Forestry and land clearing

- Can you match Sumitomo OEM part numbers?
- Yes, send the OEM part number, drawing, or sample. We cross-reference and confirm all dimensions.
- Do you offer samples?
- Sample orders are accepted before bulk production to verify fitment and quality.
- How do I confirm bolt pattern compatibility?
- Provide track pitch, bolt hole diameter, bolt center distance, and shoe width. Our engineers verify compatibility.
- Are material certificates available?
- Yes, SGS material certificates can be provided with each shipment for full traceability.
Maintenance Guide
- Check bolt torque after initial 50 operating hours; loose bolts accelerate shoe and chain wear.
- Inspect grouser height regularly. Replace shoes when grouser wear exceeds 25% or cracking appears near bolt holes.
- Keep undercarriage clean of packed debris. Abrasive material between shoes and chain increases wear.
- Use uniform bolt torque across all shoes. Uneven torque causes track misalignment and premature failure.
