D500/D600 Bulldozer Bottom Track Rollers with Temperature Range -45℃ to 120℃ and Precision Forging for Heavy Load Capacity

As a core component of belt conveyors, the roller comes in diverse types and large volumes, serving to support the conveyor belt and bear the weight of transported materials. It accounts for 35% of a belt conveyor's total cost while contributing to over 70% of the conveyor's total resistance—making its quality critically important.

Track rollers are manufactured from 40Mn2, 40MnB, or 50Mn steel, selected based on specific operating conditions. These rollers undergo precision forging followed by normalization and full heat treatment, achieving:

• Surface hardness of HRC 52-56
• Hardened layer depth over 7-10mm (maintaining HRC 45 at core)
• Exceptional durability with strong impact resistance
• Superior surface wear resistance at contact points

• Through quench-tempering processes for excellent mechanical properties
• High strength and superior wear resistance to bending and breakage
• Surface hardness HRC40-55 for reduced wear and longer life
• Heavy load capacity up to 50 tons
• Temperature range: -45℃ to 120℃
• Maintenance-free operation with high-performance floating seals
