1. What is a roller?


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 / Features

  • Our track rollers undergo specialized quench-tempering processes, which ensure they deliver excellent mechanical properties, high overall strength, and superior resistance to bending, breakage, and wear—critical for withstanding heavy-duty operational stress.
  • We take great pride in the quality of our track rollers. Leveraging our excellent heat treatment technologies, proven expertise in mining applications, and top-tier floating seals and bearings, we manufacture heavy-duty track rollers that are far more durable, built to thrive in the toughest working environments.
  • Equipped with precision-engineered components, meticulous heat treatment, and a lifetime sealing system, our track rollers guarantee long service life. Their shells are forged from deep-hardening steel, specifically designed to resist bell mouthing (a common cause of premature failure). Every roller is backed by a manufacturer’s warranty, providing added peace of mind.
