Product 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. We can tailor our manufacturing to meet OEM specifications and 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.
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. The result is exceptional durability with strong impact resistance and superior surface wear resistance.
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.
Track Roller Advantages
- Heat treatment techniques such as quenching and tempering guarantee superior mechanical characteristics, exceptional strength, and enhanced resistance to wear, bending, and fracture.
- Surface hardness levels of HRC40 to 55 minimize wear and prolong product lifespan.
- Meticulously designed for secure installation and optimal performance under heavy loads, capable of supporting up to 50 tons.
- High cost-performance ratio and excellent service, making them the top choice for your needs.
