Kato Track Group Manufacturing & Supply
Dingtai manufactures complete Kato track groups—link assemblies, pins, bushings, shoes, and hardware—forming the excavator’s primary undercarriage traction system on crawler machines.
Factory-direct from China, Dingtai supplies full OEM replacement track groups to global distributors and fleet owners, offering competitive pricing, engineering support, and production flexibility.
Our heat-treated track groups resist elongation, cracking, and pin wear under heavy loads, reducing unplanned downtime and extending undercarriage service intervals in demanding conditions.
With 20+ years in undercarriage manufacturing and ISO9001/SGS-certified processes, Dingtai ensures consistent metallurgy, dimensional accuracy, and verified wear life on every batch.
Track links use 35MnB steel with deep induction quenching to HRC 48–55, providing high tensile strength, impact resistance, and controlled wear across the chain.
Core Selling Points
- Global Brand Compatibility: We produce Kato track groups matching OEM dimensions for HD and other series, ensuring direct bolt-on installation without field modification.
- Premium 35MnB Material: Forged and machined from 35MnB steel, our track links provide high tensile strength and resistance to bending under severe excavator loads.
- Deep Quenching/Heat Treatment: Induction hardening achieves specified case depth and HRC 48–55 on link rails and pin surfaces, maximizing wear life and reducing downtime.
- 100% QC Inspection: Each track group undergoes dimensional checks, hardness testing, and assembly verification before shipment, ensuring zero-defect delivery to your warehouse or job site.

Technical Features
Track links are precision forged and induction hardened to create deep wear-resistant rail surfaces while maintaining a ductile core for impact resistance.
Sealed and lubricated track groups use floating seals to retain internal lubricant and block abrasive sand, extending pin and bushing service life.
Pitch accuracy and link face alignment are tightly controlled during machining to reduce sprocket engagement shock and improve undercarriage stability.
Applications

- Road Construction
- Quarrying
- Demolition
- Heavy Earthmoving
- Forestry
Frequently Asked Questions
1. What is the minimum order quantity for Kato track groups?
Standard MOQ is one set, with better pricing for container quantities. Mixed models are acceptable.
2. What is the typical delivery time?
Standard production takes 20–30 days. Custom dimensions or special packing may require additional lead time.
3. What heat treatment depth and hardness do you guarantee?
We guarantee HRC 48–55 on link rails and controlled case depth on pins and bushings per OEM requirements.
4. How do I confirm part number compatibility?
Send your Kato part number, pitch, shoe width, and link count. Our engineers verify before production.
5. What warranty is provided?
We provide a 12-month warranty against material and manufacturing defects under normal operating conditions.
6. Can you produce custom shoe widths or link pitch?
Yes. We manufacture to customer drawings, including non-standard shoe widths, link pitch, and bolt patterns.
Maintenance Guide
- Inspect track sag daily and adjust tension to OEM specifications to prevent accelerated rail and sprocket wear.
- Check pin/bushing lubrication leaks and shoe bolt torque every 250 operating hours.
- Measure link rail wear and bushing outside diameter; replace at 20–30% wear to protect sprocket life.
- During installation, align the master pin correctly and retorque shoe bolts after 8–10 operating hours.
