Daewoo DH55 High Duty Forged Steel Top Carrier Roller with HRC52-60 Hardness and 7-10mm Hardened Layer ISO9001 Certified

Carrier rollers are critical components in undercarriage systems, supporting conveyor belts and bearing material weight. Their quality directly impacts the service life of excavators and bulldozers. For belt conveyors, rollers account for 35% of total conveyor cost and generate over 70% of system resistance, making quality essential. Available in two main materials: steel and plastic.

For heavy machinery undercarriages, carrier rollers are manufactured from high-grade materials (40Mn2, 40MnB, 50Mn) selected for specific working conditions. The production process includes:

• Precision forging
• Normalization
• Overall heat treatment

This achieves HRC52-60 surface hardness with 7-10mm hardened layer (HRC45), ensuring exceptional durability, impact resistance, and wear resistance.

• Equipped with high-quality floating seals and reliable lubrication systems
• Operates in temperatures from -45℃ to 120℃
• Maintenance-free design ideal for mining and construction applications

Crafted from high-strength alloy steel through advanced hot-forging, these carrier rollers offer superior durability. Designed to withstand extreme loads and impacts, they perform reliably in demanding environments including rocky terrain and compacted soil.

Precision-engineered for perfect track alignment, these rollers reduce friction and wear, extending undercarriage life by 40% compared to traditional models. This results in fewer replacements, lower maintenance costs, and increased productivity.

Designed for easy upkeep with sealed lubrication (reducing dirt intrusion) and tool-free disassembly, cutting maintenance time by 30%. Reduced wear means longer service intervals and minimized downtime.
