Introduction to track roller material
1. Cast steel rollers
Cast steel rollers usually use low-alloy structural steel and carbon steel as the main raw materials, which have the advantages of high strength, wear resistance, and impact resistance. The manufacturing process of cast steel rollers is relatively simple and can withstand larger loads, so they are more common in the production of large crawler machines.
2. Forged steel rollers
Compared with cast steel rollers, forged steel rollers have higher strength, hardness and toughness, and are an excellent material. The manufacturing process of forged steel rollers is relatively complex and requires multiple process steps such as pore removal, trimming, and annealing. Forged steel rollers are widely used in high-end crawler machines due to their excellent performance and cost considerations.
3. Cast iron rollers
Cast iron rollers have good wear resistance and strength, but compared to cast steel and forged steel, cast iron material has poorer strength and toughness. Cast iron rollers occupy a better balance point in terms of manufacturing cost and performance, and are therefore widely used in some small and medium-sized crawlers.
4. Rubber rollers
Rubber rollers are rollers made of rubber. They have the characteristics of light weight, good shock absorption, and reduced ground damage. They are widely used in small crawlers and some special occasions.
