Why Choose Tianyou Spare Parts?
Precision manufacturing for ultimate pelleting performance.
Bearing Steel Forging
High-quality bearing steel forging eliminates internal defects.
Precision Assembly
Each assembly is balanced and tested for smooth operation.
Sealed Bearing System
Premium sealed bearings protect against dust contamination.
Premium Material & Extended Lifespan
Forged from high-grade 20CrMnTi (Alloy Steel), our replacement ring dies and roller shells offer superior resistance against corrosion and abrasive wear during high-temperature pelleting. Processed through advanced vacuum heat treatment, we ensure a uniform hardness (typically HRC 52-56), which maximizes output capacity while minimizing the cost per ton of feed produced.
