Dingtai manufactures Hitachi-compatible track guards that protect track rollers, idlers, and final drives from rock impact and debris ingress in undercarriage systems.
We provide factory-direct supply and full OEM manufacturing services, supporting global distributors, dealers, and equipment fleets with precision-matched track guard production.
These guards reduce unplanned downtime by shielding undercarriage components from abrasive rock damage, frame stress, and costly track derailment or roller failure.
With over 20 years of engineering machinery experience and ISO9001/SGS-certified processes, Dingtai delivers traceable material quality and repeatable dimensional accuracy.
Our guards use 35MnB high-strength steel and deep quenching technology, delivering high-hardness wear surfaces and tough cores for extreme site conditions.
Core Selling Points
- Premium 35MnB Material: High-yield 35MnB steel gives the guard superior resistance to impact, bending, and abrasive wear in rocky or high-debris undercarriage environments.
- Deep Quenching/Heat Treatment: Controlled deep quenching raises surface hardness to HRC 42–52 while maintaining core toughness, reducing cracking and extending service life.
- Global Brand Compatibility: Direct replacement for Hitachi track systems, with OEM-matched mounting hole positions, bolt spacing, and profile dimensions for fast installation.
- 100% QC Inspection: Every batch undergoes dimensional inspection, hardness testing, and surface checks before packing, ensuring consistent fit and performance.

Delivery & Logistics
We provide factory-direct pricing, sturdy export packing, and flexible order quantities. Standard shipping uses plywood pallets or steel frames to prevent transport damage.
Technical Features
Track guards act as sacrificial barriers, absorbing rock strikes and sliding abrasion before they reach rollers, idlers, and final drive housings.
Reinforced vertical ribs and precision pre-drilled mounting holes distribute impact energy across the undercarriage frame, preventing stress concentration and bolt loosening.
Deep quenching creates a hard wear surface while retaining core ductility, resisting abrasive wear and avoiding brittle fracture in mining applications.
Applications
- Mining: Protects undercarriages from fractured rock, ore spillage, and heavy shock loads.
- Road Construction: Shields track components from crushed concrete, demolition debris, and curb contact.
- Quarrying: Reduces abrasive wear caused by blasted rock loading and haul road debris.
- Heavy Civil Works: Guards against pipe, rebar, and mixed spoil damage during deep excavation.
Frequently Asked Questions
1. What is the MOQ for Hitachi track guards?
Standard MOQ is 4 units per part number. Mixed specifications are accepted for initial trial orders.
2. What is the delivery time?
Stock specifications ship in 15–25 days. Custom OEM production usually requires 30–45 days depending on quantity and machining.
3. What heat treatment depth and hardness do you provide?
Typical effective hardening depth is 6–12 mm, with surface hardness controlled between HRC 42 and HRC 52 based on plate thickness.
4. What is the warranty policy?
We provide a 12-month warranty against material and manufacturing defects. Normal wear, abuse, or improper installation is not covered.
5. Can you match Hitachi part numbers?
Yes. Send OE part numbers or drawings; we cross-check specifications and produce direct replacement guards with correct bolt-hole spacing.
6. Do you offer sample orders?
Yes. Sample orders are available for evaluation. Sample cost is typically credited against the first bulk order.
7. What certifications do you have?
Dingtai holds ISO9001:2015 certification. SGS or third-party mill test reports are available on request.
Maintenance Guide
- Installation: Verify bolt-hole alignment before torquing. Use grade 10.9 fasteners and tighten in a diagonal sequence to seat the guard evenly.
- Routine Inspection: Check guards every 250 service hours for cracks, deformation, or loose bolts, especially after rock impact or high-debris operations.
- Wear Limits: Replace when thickness is reduced by 30% or mounting holes become elongated. Delayed replacement can transfer damage to the track frame.
- Surface Care: Keep mounting surfaces clean and repaint exposed steel after installation. Do not weld cracked guards under load-bearing areas.
