Engineered to withstand extreme tensile loads, high rotational speeds, and demanding continuous operation across Pohang, Gwangyang, Incheon, and Busan industrial zones.
South Korea represents one of the world's most advanced, automated, and quality-conscious industrial economies. From steel giants in Pohang and Dangjin to mega transshipment hubs in Busan, continuous conveyor reliability is paramount.
South Korea’s steel complexes handle hundreds of thousands of tons of raw iron ore, pulverized coal, and sintered additives daily. In extreme thermal environments near blast furnaces and coke ovens, conveyor idlers must provide flawless rotational concentricity, heavy impact dampening, and advanced labyrinth seals that block fine sinter dust from penetrating bearing housings.
As vital Northeast Asian transshipment hubs, South Korean ports require continuous high-speed shiploading and bulk discharge. Humid, saline maritime atmospheres demand corrosion-resistant roller shells, specialized galvanized or polyurethane-coated idler frames, and low Total Indicated Runout (TIR) to prevent conveyor belt tracking misalignment during 24/7 unloader runs.
Thermal power complexes under KEPCO subsidiaries and cement production clusters in Gangwon and Chungbuk provinces are rapidly transitioning toward zero-dust emissions and ESG energy conservation. Boao Jinao ultra-low-friction idlers reduce motor driving kilowatts, reduce noise levels below 70 dBA, and support enclosed eco-pipe conveyor networks.
Precision-manufactured in compliance with KS (Korean Industrial Standards), JIS B8803, ISO 1537, and CEMA Classifications, guaranteeing seamless interchangeability and extended operational lifespans.
Deep-trough 3-roll and 5-roll configurations equipped with high-precision electric resistance welded (ERW) steel tubes, CNC-machined shaft ends, and multi-labyrinth sealing systems for high-capacity bulk transport.
High-resilience rubber ring construction located under feed chutes and transfer hoppers. Absorbs extreme kinetic energy from dropping ores, preventing conveyor belt carcass punctures and premature core degradation.
Friction-responsive and guide-roller actuated tracking idlers that automatically steer drifting belts back onto the structural center line, preventing costly edge tears and material spillage across automated circuits.
High-hardness ceramic lagged shells and anti-stick composite sleeves engineered specifically for highly abrasive Korean silica sand, coal slurry, wet chemicals, and sticky clay environments.
Hebei Boao Rubber Technology Co., Ltd. is located in the Rubber Industrial Park of Boye County, Baoding, Hebei Province. The company was founded in 2004 and covers an area of over 30 acres.
Product brand "Jinao" brand. We are a professional manufacturer in China that integrates product development, research, design, manufacturing, and business services for conveyor belts and conveyor machinery accessories. We have also passed the international quality management system certification in one go. The company has multiple advanced equipment production lines for rolling, forming, vulcanization, and rubber testing (from raw materials to finished products).
The company has an independent chemical analysis room and physics laboratory, which can ensure timely monitoring of every link from raw material procurement to product delivery. It strictly follows the principle of not entering the site for unqualified products and not leaving the site for products that do not meet standards.
Professional quality inspectors, sophisticated experimental testing equipment, and advanced testing methods ensure the quality of the company's products.
With strong technical strength and a comprehensive after-sales system, our products are exported to various parts of the country and international heavy industry sectors. Widely used in industries such as steel, metallurgy, coal, cement, power generation, fertilizers, grain depots, ports, etc.
Today, Hebei Boao Rubber Technology Co., Ltd. will be built into a domestic and international production-oriented enterprise with modern equipment, diversified products, and global market presence, presenting itself in the new century with a brand new attitude.
Ordinary conveyor belts (NN, EP, PP), heat-resistant conveyor belts, circular belts, high-temperature resistant conveyor belts, cold resistant conveyor belts, oil and alkali resistant conveyor belts, acid and alkali resistant conveyor belts, rubber waterstop belts, patterned conveyor belts (herringbone, pit), high inclination conveyor belts, wavy edge conveyor belts, steel cord belts, and enclosed pipe conveyor belts.
Roller series accessories, ceramic rollers, buffering rollers, roller groups, blocking edges, rollers, and other roller series accessories, electric rollers, rubber coated rollers, transmission rollers, strong magnetic rollers, brackets, and other accessories, groove brackets, centering brackets, tensioning brackets, lifting ears, and heavy-duty idler frames.
South Korean industrial facilities operate under rigorous continuous monitoring, stringent environmental standards, and demanding total-cost-of-ownership (TCO) benchmarks.
Our conveyor idlers feature a patented 4-piece non-contact labyrinth seal combined with an outer rain cap and nylon dust cover. This completely shields the deep groove ball bearings (SKF, NSK, or FAG grade) from abrasive mineral fines, moisture, and saltwater spray in coastal ports like Busan and Incheon.
Using automated cold-drawn seamless shafting and dual-end robotic boring, our idlers achieve runout tolerance within ±0.3mm. Low rotational resistance significantly cuts continuous electric motor consumption across long-distance overland conveyor conveyors in South Korean power and mining sites.
All roller diameters (Φ89mm, Φ108mm, Φ133mm, Φ159mm, Φ194mm, Φ219mm) and shaft end millings (flat slot, threaded, external circlip) strictly match South Korean equipment specifications, ensuring seamless plug-and-play retrofit during plant scheduled maintenance.
Supplying industry leaders across heavy manufacturing, bulk agribusiness, mining, and maritime trade.
Rigorous compliance with international quality, safety, and environmental management certifications.
Demonstrated operational life exceeding 35,000 continuous hours in heavy-duty South Korean material handling facilities.
Equipped 45° heavy-duty impact and carry trough idler sets along a 3.2km overland iron ore supply circuit. Successfully reduced idler bearing contamination failure rate by 82% in severe abrasive fine-dust conditions.
Delivered dynamic balanced return rollers and self-aligning training sets to offshore grain and chemical unloading terminals. Resolved high-speed belt tracking deviations and reduced operational noise to under 68 dBA.
Integrated anti-corrosion rubber-disc return rollers and wear-resistant primary idler arrays on primary rock crushers, handling sharp limestone aggregate up to 250mm lump sizes without bearing seizure.
