About this product

Product information from the supplier.

The Troughing Roller is a critical component of belt conveyor idler systems, meticulously engineered to support the conveyor belt and shape it into a trough profile. This design optimizes material containment and prevents spillage during high-capacity transport. Constructed from premium steel pipes and integrated with high-precision bearings and seals, our rollers ensure seamless material flow across diverse industrial environments.

Our proprietary manufacturing process utilizes an advanced excircle flanging technique for the bearing housing, which significantly enhances fixation stability and ensures superior concentricity between the outer circle and the bearing chamber. By employing interference fit welding, we eliminate accumulated processing errors and correct steel pipe ellipticity, ensuring that the radial runout index reaches an optimal level for maximum operational efficiency (Patent No: ZL200720175474.5).
