High-performance idlers, belting solutions, and accessories engineered to Van Gorp and global standards for continuous operations.
In the contemporary macro-industrial framework, efficiency in high-tonnage bulk handling dictates profitability across key resource sectors—including iron ore mining, hard-rock quarrying, cement manufacturing, coal-fired power production, and heavy metallurgical plant logistics.
Over 40% of standard conveyor electrical resistance stems from idler dynamic rotational drag and belt deformation over rollers. Upgrading to precision-machined Van Gorp style idler components drastically cuts rotational friction coefficient (down to ≤0.018), minimizing parasitic kWh load on major drive pulleys.
Industrial conveyor failures are 65% attributable to bearing collapse caused by abrasive dust and water ingress. Engineered multi-stage triple-labyrinth seal systems provide complete barrier protection against micro-particulates, ensuring uninterrupted 24/7 continuous operation.
Unscheduled belt conveyor downtime costs heavy processing plants thousands of dollars per hour. Utilizing Van Gorp compatible dimensional standards ensures seamless drop-in replacements, extending MTBF (Mean Time Between Failures) and lowering long-term system life-cycle expenditure.
Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province. Founded in 2004, the enterprise covers an area of over 30 acres and manufactures under the prestigious "Jinao" brand.
Hebei Boao Rubber Technology Co., Ltd. is a leading enterprise in China integrating product design, advanced R&D, chemical synthesis, metal fabrication, vulcanization, and continuous technical business services for high-capacity conveyor belts and precision conveyor machinery accessories. Operating multiple specialized production lines for rolling, mechanical forming, vulcanizing, and precision shaft machining, we maintain complete control over component quality.
We have passed the international quality management system certification in one go. Every step of raw material receipt, roller shell extrusion, bearing housing welding, and final balance testing strictly conforms to ISO standards.
Quality assurance at Boao relies on a dedicated chemical analysis facility and advanced physical testing laboratory. We enforce a zero-tolerance policy: uninspected raw materials cannot enter processing lines, and finished products missing performance tolerances are strictly denied factory clearance.





Van Gorp idlers are internationally recognized for structural durability, dimensional reliability, and alignment precision. As a premier global supplier and manufacturer, Hebei Boao Rubber Technology Co., Ltd. engineers Van Gorp style idlers engineered to match or exceed CEMA (Conveyor Equipment Manufacturers Association) B, C, D, E, and F standards.
Manufactured using heavy-wall ERW electronic resistance welded steel pipe designed specifically for conveyor rolls. Pipe ends are internally bored simultaneously with bearing housing fitment to eliminate radial eccentricities.
Features an inner seal, a multi-slot nylon or steel triple-labyrinth outer barrier, and an external rain/dust cap filled with high-temperature lithium complex grease to completely seal out mud, water, and gritty abrasives.
Outfitted with C3 clearance deep groove ball bearings (20mm to 50mm shaft sizes) sourced from top-tier bearing steel suppliers, providing extended dynamic load capacity for intense shock-load zone impact.
