Case Bulldozer Track Chain Assembly
We manufacture Case bulldozer track chain assemblies, linking track shoes and transmitting drive force across the undercarriage system under extreme load conditions.
Factory-direct production supports complete OEM manufacturing services, serving replacement markets and equipment distributors globally with consistent quality and competitive pricing.
Through-hardened link pins and bushings resist abrasive wear and elongation, reducing premature failure and costly machine downtime on demanding construction and mining sites.
With over 20 years of experience and ISO9001/SGS-certified processes, Dingtai delivers repeatable quality for heavy machinery procurement professionals worldwide.
Premium 35MnB steel, precision heat treatment, and deep quenching ensure high hardness, impact toughness, and extended service life under continuous track tension.
Core Selling Points
- Premium 35MnB Material: Forged from 35MnB steel to withstand high impact, bending stress, and abrasive wear in severe bulldozer applications.
- Deep Quenching/Heat Treatment: Induction hardening and tempering achieve consistent hardness depth, improving link and bushing fatigue resistance under continuous track tension.
- 100% QC Inspection: Every assembly undergoes dimensional checks, hardness testing, and surface inspection before packing, ensuring zero-defect delivery for critical replacements.
- OEM Capabilities: We produce exact-fit assemblies from customer drawings or samples, matching OEM part numbers and pitch dimensions for Case and other brands.

Technical Features
Track chain pins and bushings operate as wear pairs. Controlled interference fit and lubrication prevent abrasive ingress, reducing internal pitch extension.
Induction-hardened 35MnB links deliver deep hardness layers without brittle cores, improving fatigue strength under rock impact and side loading.
Sealed and lubricated options use floating seals to retain oil and block contamination, extending service intervals in abrasive mining conditions.
Applications
- Mining
- Road Construction
- Quarrying
- Land Clearing
- Heavy Demolition
- Forestry
Frequently Asked Questions
- What is the MOQ for Case bulldozer track chain assemblies?
Standard MOQ is 2-4 pieces depending on specifications; sample orders and trial batches can be arranged. - What is the delivery time?
Standard production takes 20-35 days. Stock items ship faster; container orders depend on quantity and customization. - How deep is the heat treatment?
Link induction hardening typically reaches 4-8 mm depth; pins and bushings are through-hardened or case-hardened to specified HRC. - What warranty policy applies?
Dingtai provides 12 months or 2,000 operating hours warranty against material and manufacturing defects under normal use. - Can you match original Case part numbers?
Yes. Supply OEM part numbers, pitch, link count, or drawings and we produce exact-fit replacements with equivalent specifications. - Do you provide samples?
Yes, sample assemblies or sections can be supplied for inspection, hardness testing, and fitment confirmation before bulk order.
Maintenance Guide
- Inspect track tension weekly. Excessive sag accelerates link and bushing wear, especially in rocky or abrasive working conditions.
- Check pin and bushing wear by measuring track pitch elongation. Replace chains when elongation exceeds 3% of original pitch.
- Clean undercarriage after operation to remove packed debris, which causes friction heat and shortens seal and link life.
- Tighten track shoe bolts to specified torque during first 50 hours and every 250 hours thereafter.
- Replace both track chain assemblies simultaneously to maintain balanced traction and prevent uneven drive component loading.
