Dingtai manufactures heavy-duty track guards that shield the undercarriage system from rock intrusion, impact damage, and debris accumulation on excavators and bulldozers.
As a factory-direct supplier, we offer complete OEM manufacturing—from precision forging and heat treatment to final machining—tailored for global heavy machinery buyers.
Our robust guard design prevents premature wear on track chains and rollers, reducing unscheduled downtime and costly final drive repairs in severe working conditions.
Backed by over 20 years of expertise and ISO9001/SGS certification, our manufacturing consistently meets exacting international quality and performance requirements.
Forged from 35MnB boron steel and deep induction quenched, the guards achieve a surface hardness of 52-58 HRC, delivering exceptional resistance to abrasion and impact.
Core Advantages
- Premium 35MnB Material: High-tensile boron steel with excellent hardenability delivers superior strength and fatigue resistance compared to standard carbon steel castings.
- Deep Quenching/Heat Treatment: Induction hardening penetrates 4-8 mm deep, creating a wear-resistant martensitic surface while retaining a tough, shock-absorbent core.
- Precision Forging/Casting: Closed-die hot forging ensures isotropic grain flow and eliminates internal voids, providing structural integrity that cast alternatives cannot match.
- Global Brand Compatibility: Engineered to exactly replace Caterpillar track guards; dimensional accuracy and bolt-pattern alignment guarantee a seamless fit on all listed models.
Our catalog of Caterpillar Track Guard includes various specifications, fully compatible with Caterpillar excavators and bulldozers.

Technical Features
Forged from solid 35MnB billets, each guard features isotropic grain flow that yields dramatic toughness improvements over cast guards, effectively resisting impact cracks in rocky terrain.
Deep induction hardening transforms the outer layer into a hard martensitic shell with 52-58 HRC, while the softer core absorbs heavy shock loads without brittle fracture.
Mounting bosses are precision bored and reinforced with thicker cross-sections to eliminate bolt loosening under sustained vibration, preserving guard alignment over thousands of hours.

Frequently Asked Questions
- What is the minimum order quantity (MOQ)?
- Our standard MOQ is 10 pieces per part number, but we often accommodate smaller trial orders for first-time buyers.
- What is the typical delivery time?
- Standard production lead time is 25-35 days after order confirmation; express air freight can be arranged for urgent requirements.
- What heat treatment depth do you guarantee?
- We guarantee a minimum induction hardening depth of 4 mm, typically reaching 8 mm, achieving a consistent 52-58 HRC rockwell hardness.
- What is the warranty policy?
- All track guards carry a 12-month or 2000-working-hour warranty against manufacturing defects under normal operating conditions.
- Can you cross-reference Caterpillar part numbers?
- Yes, we match OEM numbers such as 234-2508, 234-2509, and 8E-5366, ensuring precise form, fit, and function.
Maintenance Guide
- Inspect track guards weekly for cracks, deformation, or loose bolts—paying special attention to lower impact zones.
- Re-torque all mounting bolts to factory specifications (typically 600-800 Nm) after the first 50 hours of operation.
- Replace any guard when material thickness is worn beyond 30% of the original dimension or if structural welds are compromised.
- Remove packed debris between guard and track frame regularly to prevent stress concentrations and hidden corrosion.
