Mitsubishi Track Link Assembly
Dingtai manufactures Mitsubishi track link assemblies connecting track shoes into a sealed track chain that transfers drive force through the undercarriage.
We supply factory-direct track link assemblies with full OEM manufacturing services for US and global heavy equipment distributors.
Our through-hardened links resist elongation, sprocket skipping, and pin turn, reducing unplanned downtime in abrasive undercarriage environments.
With over 20 years of undercarriage manufacturing and ISO9001/SGS-certified processes, Dingtai provides repeatable quality for critical Mitsubishi fleet applications.
We use 35MnB steel, induction hardening, and precision machining to deliver track link assemblies with consistent hardness and extended service life.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB alloy steel for high tensile strength, impact resistance, and longer wear life in demanding undercarriage applications.
- Deep Quenching/Heat Treatment: Track links are induction-hardened to HRC 48–56, creating a deep hardened case that resists abrasive wear and elongation.
- Global Brand Compatibility: Direct interchange with Mitsubishi OEM part numbers and common aftermarket dimensions for excavator and bulldozer undercarriages.
- 100% QC Inspection: Each link assembly passes dimensional, hardness, and magnetic particle inspection before release, ensuring zero-defect batch consistency.

Technical Features
Track link assemblies use precision-machined pin and bushing interference fits to maintain press engagement and prevent internal wear.
Induction hardening creates a martensitic wear layer on the rail surface while retaining a tough core, resisting cracking.
Sealed and lubricated designs keep fine abrasives from entering the pin-bushing joint, extending track chain life.
Applications
- Mining operations
- Road construction
- Quarrying and aggregate
- Demolition
- Forestry and land clearing
- Heavy civil earthworks
Frequently Asked Questions
What is the MOQ for Mitsubishi track link assemblies?
Standard MOQ is one full track chain assembly or 20 link sections, depending on the model. Sample links may be available for inspection.
How long is delivery?
Standard production time is 20–30 days after drawing confirmation. FOB Quanzhou shipping to US ports adds 15–25 days.
What heat treatment depth is applied?
Link rail surfaces are induction-hardened to HRC 48–56 with a hardened case depth of 4–8 mm depending on link size.
What is the warranty policy?
12 months or 2,000 working hours from shipment, whichever occurs first, covering material and manufacturing defects under normal use.
Can you match part numbers?
Yes. Provide the OEM part number or track pitch, link quantity, and shoe bolt pattern; we confirm interchange before production.
Are these compatible with aftermarket chains?
Yes, we manufacture to standard Mitsubishi pitch and bushing dimensions for direct replacement on OEM and aftermarket chains.
Maintenance Guide
- Installation: Check track tension and pin boss alignment before installation; never force links with hydraulic pressure.
- Daily Inspection: Inspect link rail wear height, sprocket tooth engagement, and pin retention every 250 operating hours.
- Signs of Wear: Replace link assemblies when rail height is worn to service limit or pin/bushing internal clearance exceeds OEM tolerance.
- Replacement Interval: Under normal conditions, inspect at 1,500 hours and plan replacement between 3,000–4,000 hours depending on abrasion.
