Dingtai manufactures complete Case track groups—chains, shoes, pins, bushings, and hardware—for crawler undercarriage traction and stability.
We supply factory-direct track groups with full OEM manufacturing capabilities, supporting North American dealers and aftermarket buyers with consistent specifications and competitive pricing.
Our track groups reduce unplanned downtime by resisting elongation, pin wear, and shoe cracking in abrasive undercarriage conditions on Case machines.
Dingtai has over 20 years of undercarriage manufacturing experience and holds ISO9001/SGS certifications, ensuring traceable quality for every production batch.
We use 35MnB link material, deep quenching, and sealed lubricated track technology to extend service life under heavy impact loads.
Core Selling Points
- Premium 35MnB Material: Track links are forged from 35MnB steel, offering high tensile strength and resistance to bending or cracking under heavy loads.
- Deep Quenching/Heat Treatment: Link and pin surfaces receive deep induction hardening to HRC 52-58, creating a wear-resistant case while retaining core toughness.
- OEM Capabilities: We match original Case part numbers and drawings, producing bolt-on track groups without field modification or fitment risk.
- ISO9001/SGS Certified: Production processes follow ISO9001 quality systems; material batches are verified by SGS reports for full supply chain confidence.
Our catalog of Case track groups includes various specifications, fully compatible with Case excavators, dozers, and track loaders.

Delivery & Logistics
Factory-direct pricing, reliable ocean and express shipping, and flexible MOQs support both urgent replacement orders and large fleet programs.
Technical Features
Sealed and lubricated track (SALT) design retains oil between pin and bushing, minimizing internal wear and reducing track pitch elongation.
Deep induction hardening produces a hard wear surface while maintaining ductile core, preventing brittle fractures under rock impact.
Precision-machined link bores and pressed pins ensure uniform load distribution across the track group, reducing hot spots and premature failure.
Applications
- Mining: hard rock and overburden removal
- Road construction: base preparation and grading
- Quarrying: stone extraction and haul road maintenance
- Land clearing and forestry
- Demolition and site preparation
Frequently Asked Questions
What is the minimum order quantity for Case track groups?
We accept one complete track group per side for trial orders. Bulk production MOQ is typically two units per part number.
How long is delivery?
Standard production takes 15-25 days after deposit confirmation. Urgent stock items can ship within 7 days depending on specification.
How deep is the heat treatment on track links and bushings?
Link wear surfaces are induction hardened to 5-9 mm depth. Bushings receive deep-case carburizing to HRC 55-60.
What is the warranty policy?
Dingtai provides 12 months or 2,000 operating hours against manufacturing defects under normal working conditions.
Can you match Case OEM part numbers?
Yes. Provide the Case part number or drawing. We verify all dimensions before production and confirm interchangeability.
Do you supply complete track groups or individual components?
Both complete assembled track groups and individual links, shoes, pins, bushings, and hardware are available.
Are your track groups compatible with sealed and lubricated track systems?
Yes. SALT track groups are available for Case dozers and excavators requiring sealed and lubricated chain assemblies.
Maintenance Guide
- Verify track tension after installation. Overtightening accelerates pin and bushing wear and increases final drive load.
- Inspect for dry joints, missing shoe bolts, and uneven shoe wear every 250 operating hours.
- Replace track groups when bushing outer diameter wear exceeds 20% or link pitch elongation exceeds 2.5%.
- Remove mud and debris from track frames to prevent packing and accelerated roller flange wear.
- Rotate or replace sprockets with track groups on applicable Case models to avoid mismatched pitch wear.
