Dingtai manufactures Case track guards that protect track chains, rollers, and idlers from rock impact and abrasive debris.
We offer factory-direct supply and full OEM manufacturing services, eliminating intermediaries and ensuring consistent quality for global equipment buyers.
Heavy-duty guard structures reduce track derailment and premature component wear, minimizing unplanned downtime in mining, quarrying, and demolition applications.
With over 20 years of undercarriage manufacturing experience, Dingtai holds ISO9001 and SGS certifications, delivering verified reliability for procurement professionals.
Our track guards use 35MnB steel and deep quenching heat treatment to achieve high surface hardness and impact toughness under extreme load conditions.
Core Selling Points
- Premium 35MnB Material: Manufactured from high-strength 35MnB steel, track guards deliver superior bending fatigue resistance and longer service life in abrasive conditions.
- Deep Quenching/Heat Treatment: Advanced heat treatment produces a hardened wear surface with a tough core, reducing deformation and extending replacement intervals.
- Global Brand Compatibility: Direct replacement for Case excavators and dozers, engineered to match OEM mounting dimensions without field modification.
- 100% QC Inspection: Every batch undergoes dimensional inspection and hardness testing, ensuring consistent fitment and performance before shipment.
Our catalog of Case Track Guard includes various specifications, fully compatible with Case excavators and bulldozers.

Delivery & Logistics
Factory-direct pricing, flexible MOQ, and reliable sea/land freight from Quanzhou ensure cost-efficient delivery to US and global job sites.
Technical Features
The reinforced sloped profile deflects rock and debris away from track links and roller mounting points, reducing direct impact damage.
Deep-quenched 35MnB steel creates a hard wear surface over a ductile core, offering high abrasion resistance without brittle failure.
Precision-machined mounting faces ensure full contact with the track frame, maintaining correct guard alignment and preventing bolt loosening.
Applications
- Mining: protects undercarriage from rock impact and abrasive ore spillage.
- Road Construction: reduces track wear in crushed aggregate and milled asphalt conditions.
- Quarrying: shields track frame components from sharp blast rock and heavy dust.
- Demolition: withstands concrete debris and rebar contact during site clearing.
- Forestry: guards against stumps and slash in rough terrain operations.
Frequently Asked Questions
What is the minimum order quantity for Case track guards?
MOQ is typically 8–10 pieces per specification, depending on casting and machining batch requirements; mixed models are accepted.
How long is delivery?
Standard production takes 25–35 days after deposit; stock items ship within 7 days.
What heat treatment depth is used?
Track guards are deep-quenched to HRC 48–55 on wear surfaces, with an effective hardening depth of 8–12 mm.
What warranty is provided?
We offer a 12-month/2,000-hour warranty against manufacturing defects under normal operating conditions.
Can you produce using Case OEM part numbers?
Yes. Provide the Case part number or drawing; we cross-reference dimensions and produce direct replacement guards.
Are samples available?
Samples can be supplied for evaluation; sample cost is refundable against bulk orders.
Maintenance Guide
- Clean track frame mounting surfaces before installation and verify guard part numbers against the machine model.
- Torque mounting bolts in a cross pattern to OEM values to ensure even clamping and prevent stress concentration.
- Inspect guards every 250 operating hours for cracks, wear grooves, or loose hardware; replace damaged guards immediately.
- Monitor undercarriage alignment and replace guards when wear depth exceeds manufacturer limits to avoid track frame damage.
