Daewoo DH55 Bulldozer Undercarriage Spare Parts High Duty Forged Steel Top Carrier Roller With Heat-treatment

1. What is Carrier Roller?

Carrier rollers are critical to undercarriages—supporting conveyor belts and material weight, with their quality directly affecting excavator/dozer service life. For belt conveyors, rollers are equally essential: diverse in type, high in quantity, they bear belt/material loads, account for 35% of total conveyor cost, and generate over 70% of system resistance (making quality vital). They come in two main materials: steel and plastic.

For heavy machinery undercarriage carrier rollers, materials (40Mn2, 40MnB, 50Mn) are chosen by working conditions. They go through strict manufacturing: precision forging → normalization → overall heat treatment, achieving HRC52-60 surface hardness and 7-10mm hardened layer (HRC45)—ensuring durability, impact resistance, and wear resistance.

Fitted with high-quality floating seals and reliable lubrication systems, track/carrier rollers adapt to diverse climates. They work stably in severe conditions or -45℃ to 120℃ temperatures, staying maintenance-free—ideal for mining and construction.

2.Unrivaled Performance and Durability

2.1 Forged for Tough Conditions

Crafted from high-strength alloy steel via advanced hot-forging, carrier rollers offer top-tier durability. Built to withstand extreme loads and impacts, they excel in construction/mining—performing reliably even on rocky terrain or compacted soil.

2.2 Precision for Optimal Function

Rigorously precision-designed for flawless track alignment, these rollers cut friction/wear, extending undercarriage life by 40% vs. traditional models. This means fewer replacements, lower maintenance costs, and higher on-site productivity.

2.3 User-Friendly Maintenance

Designed with hassle-free upkeep in mind: sealed lubrication (reduces dirt intrusion) and tool-free disassembly cut maintenance time by 30%. Less wear also means longer service intervals, minimizing downtime.
