Dingtai manufactures Kobelco track guards engineered to shield idlers, rollers, and sprockets from rock, debris, and impact damage in tracked undercarriages.
We provide factory-direct supply and complete OEM manufacturing services, producing replacement guards matched to Kobelco mounting points for distributors and end users worldwide.
These guards prevent premature roller and idler failure and track derailment by blocking debris ingress, reducing unplanned downtime and repair costs.
With over 20 years of undercarriage manufacturing experience, Dingtai holds ISO9001 and SGS certifications, ensuring consistent quality across every production batch.
We use 35MnB alloy steel and deep quenching to deliver high hardness, impact resistance, and long service life under severe load conditions.
Core Advantages
- Premium 35MnB Material: Forged 35MnB alloy steel resists cracking and deformation under repeated heavy rock impact, extending guard service intervals and protecting expensive undercarriage parts.
- Deep Quenching/Heat Treatment: Uniform hardness to HRC 45-52 ensures wear resistance without brittleness, maintaining structural strength in harsh mining and quarrying conditions.
- Global Brand Compatibility: Direct replacement for Kobelco SK series and other major excavator models, with OEM hole patterns guaranteed for bolt-on installation.
- 100% QC Inspection: Every guard passes dimensional checks and hardness testing before shipment, reducing installation downtime and field rework.
Our catalog of Kobelco Track Guard includes various specifications, fully compatible with Kobelco SK series excavators and similar undercarriage platforms.

Technical Features
Our track guards use heavy-duty steel plate and ribbed reinforcement to absorb impact energy without bending or cracking under extreme load.
The mounting brackets are precisely aligned to Kobelco frame holes, preventing stress concentration and simplifying installation with standard tools.
Hardened wear surfaces resist abrasive rock scouring, while the full-length guard body blocks debris from entering the track frame.
Applications
- Mining operations with abrasive rock and ore handling
- Road construction and site preparation
- Quarrying and aggregate processing
- Demolition and heavy civil works
- Forestry and land clearing
Frequently Asked Questions
What is the minimum order quantity for Kobelco track guards?
Minimum order quantity is usually 1-5 pieces for standard Kobelco track guards; custom orders may vary by drawing requirements.
What is the delivery time?
Standard production takes 15-30 days after drawing confirmation. Shipping time depends on the destination port.
How deep is the heat treatment?
Deep quenching reaches HRC 45-52, with hardened depth typically 8-15 mm depending on material thickness and guard design.
What warranty do you provide?
We offer 12 months against manufacturing defects under normal operating conditions. Misuse and normal wear are excluded.
How do I match part numbers?
Send your Kobelco part number or frame drawing. Our engineers verify interchange and mounting dimensions before quotation.
Can you manufacture non-standard sizes?
Yes, we customize length, width, and mounting hole positions to match modified undercarriages or special application requirements.
Do you provide material certification?
Material test certificates and third-party SGS inspection reports are available on request for each shipment.
How are Kobelco track guards installed?
They are bolt-on replacements using original frame holes. No welding or frame modification is required for standard Kobelco models.
Maintenance Guide
- Inspect guard mounting bolts every 250 hours; torque to specification to prevent loosening.
- Check for severe gouges or cracks after impact; replace if structural integrity is compromised.
- Keep debris from packing between guard and track frame; hose down regularly.
- Verify alignment with idlers and rollers during undercarriage service to avoid interference.
