What makes the high-quality dozer carrier rollers we produce different?

High-quality bulldozer carrier rollers are typically made from superior materials, such as carburized steel or boron steel, which offer higher wear resistance and strength. In contrast, low-priced, cheap bulldozer carrier rollers may use ordinary steel. While these materials can meet basic requirements, they do not provide the same level of wear resistance and strength as high-quality materials.

Shaft Smoothness:

The shafts of high-quality bulldozer carrier rollers are finely machined with a high level of smoothness, which reduces friction and extends their lifespan. On the other hand, the shafts of low-priced, cheap bulldozer carrier rollers may have lower smoothness, making them prone to metal burrs that can negatively affect lubrication and longevity.

Shaft Thickness:

High-quality bulldozer carrier rollers typically feature thicker shafts to enhance their strength and resistance to deformation. In contrast, the shafts of low-priced, cheap bulldozer carrier rollers may be thinner, making them unable to withstand the same workload.

Heat Treatment Process:

High-quality bulldozer carrier rollers undergo advanced heat treatment processes, such as carburizing, quenching, and tempering, to ensure that the product's hardness and wear resistance meet the necessary requirements. Conversely, low-priced, cheap bulldozer carrier rollers may not utilize the same heat treatment processes, or the process parameters may not be strictly controlled, resulting in insufficient hardness and wear resistance.

Product Hardness:

After rigorous heat treatment, high-quality bulldozer carrier rollers typically have a hardness ranging from HRC 45 to 62, allowing them to withstand heavy loads and prolonged use. In contrast, the hardness of low-priced, cheap bulldozer carrier rollers may be lower, failing to meet the demands for high strength and wear resistance.

Overall, low-priced, cheap bulldozer carrier rollers fall short in material selection, roller surface size, shaft smoothness, shaft thickness, heat treatment processes, and product hardness compared to high-quality bulldozer carrier rollers.
