The SHINING 81XH is an ANSI-standard heavy-duty bushed roller conveyor chain engineered for extreme applications. As the reinforced variant in the 81X series, it achieves a 151.9 kN tensile strength through thicker plates and precision manufacturing. With a 66.27mm pitch for guaranteed sprocket compatibility, it is the preferred choice for lumber processing, mining, and heavy material handling. For Standard Roller Chain, MOQ=300FT.
Engineered for Unmatched Reliability in the Most Demanding Industries
SHINING's 81XH is an ANSI-standard, engineer-grade heavy-duty bushed roller conveyor chain, representing the reinforced variant within the proven 81X series. Designed to excel where standard chains fall short, it delivers the critical strength and durability required for high-load, high-impact conveying in the world's toughest environments, from lumber mills to mining operations.
Key Features & SHINING Engineering Excellence:
Superior Tensile Strength: As the heavy-duty (H) version, the 81XH features significantly thicker link plates (7.5mm / 5.55mm) compared to the base 81X model. This engineering enhancement results in a minimum tensile strength of 151.9 kN (approx. 34,500 lbf) and an average strength of 175.7 kN, providing a substantial safety margin for extreme loads.
Precision Manufacturing & Quality Assurance: Every component is manufactured to exacting tolerances. Chain plates are precision roll-formed, and all parts undergo meticulous machining, controlled heat treatment (such as carburizing), and shot peening. This process, mirroring global benchmark standards, ensures optimal wear and fatigue resistance for maximum service life.
Robust Design for Harsh Conditions: The chain boasts a solid bushing and roller construction, with increased inner plate depth (h2 max: 31.35mm) and width (b1 min: 27.70mm), enhancing its stability and ability to handle abrasive materials and misalignment.
High-Temperature Operational Capability: Engineered with operational tolerances that accommodate thermal expansion, the 81XH is designed for reliable performance in environments where temperatures exceed 200°C, preventing seizure.
Guaranteed Compatibility: Built to ANSI specifications with a pitch of 66.27 mm, it ensures seamless integration and perfect meshing with industry-standard sprockets, minimizing downtime.
Primary Applications:
This chain is the backbone of heavy-duty conveying systems across SHINING's core sectors:
Lumber & Wood Processing: The industry standard for sawmill conveyors, log hauling, stackers, and planers.
Mining, Quarrying & Cement: For heavy-duty material transfer and handling of aggregates, ore, and clinker.
General Heavy Industry: Any application requiring a robust, high-capacity conveyor chain for bulk materials in construction, steel, and pulp & paper.
