Dingtai manufactures complete Mitsubishi track groups, including track chains, shoes, idlers, and rollers, forming the load-bearing foundation of crawler undercarriage systems.
We operate factory-direct, supplying global distributors and OEM buyers with complete track groups engineered to fit Mitsubishi excavator and dozer models without modification.
Our heat-treated track groups resist elongation, bushing cracking, and link breakage, reducing unplanned machine downtime in high-impact digging and grading applications.
With over 20 years of heavy machinery manufacturing experience, Dingtai maintains ISO9001 and SGS verified production quality for consistent aftermarket performance.
Precision-forged 35MnB link steel and deep induction hardening deliver a durable track group with stable pin retention and extended wear life.
Core Selling Points
- Premium 35MnB Material: Forged track links use high-strength 35MnB steel, delivering excellent impact resistance and structural integrity under shock loads.
- Deep Quenching/Heat Treatment: Induction hardening reaches HRC 46-54 on link pin and bushing contact zones, improving wear resistance and extending service intervals.
- 100% QC Inspection: Every track group is measured for pitch, gauge, and bolt torque before dispatch, ensuring field-ready compatibility and correct assembly.
- OEM Capabilities: We manufacture to Mitsubishi drawings, part numbers, and custom specifications, matching OEM dimensional standards for direct replacement use.

Technical Features
Each Mitsubishi track group uses sealed and lubricated track chain joints: pins and bushings run in a sealed oil bath, with floating seals keeping contaminants out.
Forged 35MnB links are induction hardened around pin and bushing bores, while positive pin retention prevents link walk and reduces torsional loosening.
Triple-grouser track shoes provide aggressive traction and self-cleaning action, with hardened bolt holes and matched torque settings for secure shoe mounting.
Applications
- Surface mining and quarrying
- Road and highway construction
- Demolition and site clearing
- Heavy civil infrastructure and utility excavation
Frequently Asked Questions
What is the minimum order quantity?
One set for sample evaluation; bulk orders are negotiable based on container volume or project schedule.
How long is delivery?
Standard production takes 25-35 days; stock items ship in 7-10 days. Ocean transit to US ports adds 15-30 days.
What heat treatment depth do track links receive?
Induction hardening typically reaches 5-8 mm depth on pin and bushing contact surfaces depending on link size.
Does Dingtai offer a warranty?
Yes. We provide a 12-month or 2,000-working-hour warranty against material and manufacturing defects.
Can you match Mitsubishi part numbers?
Yes. Provide your OEM part number or drawing, and we cross-reference or reverse-engineer the correct track group dimensions.
What material are track shoes made from?
Track shoes are 40Mn2 or 45# steel, with optional induction-hardened grousers for abrasive ground conditions.
How do I know if I need a complete track group?
Replace when pitch elongation, bushing cracks, or link bottom wear exceed OEM limits or cause frequent derailment.
Maintenance Guide
- Measure track sag monthly. Replace track chain when pitch elongation exceeds 2-3% of original pitch to prevent drive sprocket damage.
- Inspect idler, sprocket, and roller contact surfaces regularly. Uneven wear often indicates misalignment, incorrect track tension, or contaminated undercarriage conditions.
- Maintain track tension per Mitsubishi OEM specifications. Over-tensioning increases bushing and sprocket wear; under-tensioning causes detracking and impact damage.
- Clean packed soil, rock, and debris from track shoes and undercarriage after operation. Debris increases rolling resistance and accelerates abrasive wear.
- Replace complete track group when link bottom wear exceeds 20-25% or bushings crack, rather than risking sudden failure in the field.
