Haihui Environmental Protection Equipment Co., Ltd. manufactures conveyor steel trough carry idlers for belt support on the carrying side. These idlers form a trough shape with 20°, 35°, or 45° angles to increase material cross-section and reduce spillage. Made from high-strength steel tube with sealed bearings, they offer impact resistance and low friction for heavy-duty applications in mining, construction, and agriculture. Precision engineering minimizes belt wear and maintenance costs. Each idler is tested for rotation resistance and radial runout before shipment. Proper trough idler selection improves belt tracking and material containment. Haihui provides custom sizes and coatings for corrosive or abrasive environments.
