Hitachi ZAX330 Excavator Undercarriage Spare Parts Track Bottom Roller With ISO9001 Certification


1. How is the roller's quality?


Our products boast superior quality and are offered at affordable rates, backed by ISO9001:2008 certification. They are meticulously designed, engineered, and produced under stringent quality management systems. Additionally, we are capable of tailoring our manufacturing to meet OEM specifications. Furthermore, we have the capability to develop new products based on customer-provided samples, design specifications, or technical blueprints.


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. Rollers are primarily available in two materials: steel and plastic.

For track rollers, the choice of material—40Mn2, 40MnB, or 50Mn—depends on specific operating conditions. These rollers undergo precision forging followed by normalization, prior to full heat treatment. This rigorous process achieves a surface hardness of HRC 52–56, with a hardened layer depth of over 7–10mm (maintaining HRC 45 at the layer core). The result is exceptional durability: the rollers deliver strong impact resistance and superior surface wear resistance at their contact points, even under heavy loads. To adapt to varying climates and temperatures, we integrate high-performance floating seals and a specialized lubrication system. This design enables both track rollers and carrier rollers to operate reliably in harsh working environments or climates, with a temperature range of -45℃ to 120℃, while ensuring the components remain maintenance-free.




2. Track Rollers Excavator Advantages


  • By employing heat treatment techniques such as quenching and tempering, we guarantee that our products possess superior mechanical characteristics, exceptional strength, and enhanced resistance to wear, bending, and fracture.
  • The surface hardness levels of HRC40 to 55 are maintained to minimize wear and prolong the lifespan of the products, thereby enhancing their value and contributing to the longevity of your business by ensuring the products' endurance.
  • Our products are meticulously designed and crafted for secure installation and optimal performance under heavy loads, capable of supporting up to 50 tons, while ensuring the reliable operation and quality of excavators. They offer a high cost-performance ratio and excellent service, making them the top choice for your needs.
