💡 Frequently Asked Questions
Q: How can buyers evaluate the true strength of a Chinese excavator undercarriage parts manufacturer?
A: Focus primarily on four indicators: 1. Production history and industry experience (e.g., Fortrak has over 15 years of manufacturing expertise); 2. Precision of core equipment (whether it possesses automated forging and heat treatment lines); 3. Quality inspection equipment (spectrometer, CMM, and hardness testing); 4. Warranty standards (commitment to no less than 1 year or 2,000 hours warranty).
High Strength Steel and Forging Heat Treatment
Construction machinery undercarriage components operate long-term in severe working conditions involving mud, sand, rocks, and heavy loads, making materials and heat treatment processes critical factors in determining their service life. Fortrak strictly selects premium high-strength structural steel (such as 40Mn2, 50Mn), ensuring superior hardenability and impact toughness through precise chemical composition control.
In manufacturing procedures, we employ advanced precision forging or high-strength casting technologies based on the stress characteristics of individual components. Subsequently, all products undergo fully automated microcomputer-controlled deep heat treatment (such as overall quenching and tempering), forming an optimized metallographic structure across the surface and core area. The surface hardness of the components reaches HRC52-58 with a deep hardened layer, significantly improving wear resistance and fatigue strength.
| Part Name | Material | Process | Hardness | Hardened Depth |
| Track Roller | 40Mn2 / 50Mn | Precision Forging + Deep Heat Treatment | HRC 52 – 58 | 8mm – 12mm |
| Carrier Roller | 50Mn | Precision Casting/Forging + Quenching | HRC 50 – 56 | 6mm – 10mm |
| Sprocket | ZG35SiMn / 35SiMn | Casting + High-Frequency Tooth Quenching | HRC 50 – 55 | 7mm – 10mm |
| Idler | 35SiMn / 40Mn2 | Precision Casting + Tread Quenching | HRC 52 – 56 | 8mm – 12mm |
💡 Frequently Asked Questions
Q: How does the heat treatment depth of track rollers and idlers affect service life?
A: Deep heat treatment ensures that as the component undergoes spalling and wear, the interior maintains extremely high hardness and strength. Fortrak‘s 8-12mm deep hardened layer increases wear life by more than 30% compared to standard parts, effectively preventing outer ring deformation and premature damage.
