24B Metric Roller Chain Sprocket \u2014 Extreme Heavy-Duty Chain Drives<\/h2>\n

The 24B at 38.1mm (1-1\/2 inch) pitch is one of the largest commonly specified ISO metric sprockets. Engineered for applications where no smaller pitch can deliver the required torque: large-scale mining conveyors, steel mill rolling drives, port equipment, and heavy crane traversing mechanisms. Available in simplex (24B-1), duplex (24B-2), triplex (24B-3) from 9 to 114 teeth.<\/p>\n

Features<\/h2>\n
\n
\n

Extreme Torque:<\/strong> 38.1mm pitch handles the highest loads in the ISO metric range. Single simplex 24B can replace multi-strand configurations of smaller pitch.<\/p>\n<\/div>\n

\n

Heavy Gauge Teeth:<\/strong> Wider, deeper tooth profiles than smaller pitch sprockets. Robust root sections resist tooth fatigue under continuous high-load operation.<\/p>\n<\/div>\n

\n

4140 Alloy Steel:<\/strong> For mining and steel mill applications with shock loading. 655-900 MPa tensile strength with induction-hardened teeth HRC 40-50.<\/p>\n<\/div>\n

\n

Split & Segmental:<\/strong> Available in split hub for chain-on replacement and segmental rim for large elevator applications where rim-only replacement is needed.<\/p>\n<\/div>\n

\n

QD \/ Taper-Lock:<\/strong> Bushed hub options for rapid installation on large shafts. Bore capacities up to 120mm+ on larger tooth counts.<\/p>\n<\/div>\n

\n

Full Certification:<\/strong> ISO 9001:2015 manufacturing. EN 10204 Type 3.1 material certs. AS\/NZS audit compatible documentation.<\/p>\n<\/div>\n<\/div>\n

Applications<\/h2>\n
\n
\"24B<\/p>\n

Heavy Mining & Steel:<\/strong> Large overland conveyors, blast furnace charging systems, coke oven drives, and heavy-gauge pan conveyors.<\/p>\n<\/div>\n

\"24B<\/p>\n

Port & Marine:<\/strong> Ship-loader chain drives, container crane traversing mechanisms, and quayside conveyor systems.<\/p>\n<\/div>\n<\/div>\n

Reviews<\/h2>\n
\n

“24B triplex on our main overland conveyor. Running under extreme dust and heat in the Pilbara. Excellent performance.” ★★★★★<\/p>\n

Chief Engineer, Karratha, Australia<\/p>\n<\/div>\n

\n

“QD bushed 24B for our steel mill. Installed in under 2 hours. No alignment issues.” ★★★★★<\/p>\n

Maintenance Mgr, Wollongong, Australia<\/p>\n<\/div>\n

\n

“Segmental rim 24B on our bucket elevator. Replaced rim during shutdown without pulling chain. Saved 4 hours.” ★★★★☆<\/p>\n

Plant Supervisor, Dhaka, Bangladesh<\/p>\n<\/div>\n

\n

“Heavy 24B sprockets for our port ship-loader. Good quality steel, material cert provided.” ★★★★★<\/p>\n

Port Engineer, Newcastle, Australia<\/p>\n<\/div>\n

\n

“Ordered custom bore 24B-1. Bore and keyway were perfect. Excellent dimensional accuracy.” ★★★★★<\/p>\n

Mechanical Engineer, Johannesburg, South Africa<\/p>\n<\/div>\n

Perguntas frequentes<\/h2>\n
\n24B vs ANSI #120?<\/summary>\n
Both have 38.1mm pitch but different roller and width specs. Not interchangeable.<\/div>\n<\/details>\n
\nCast iron 24B available?<\/summary>\n
Yes. Cast iron 24B sprockets for low-speed, high-torque applications where vibration damping is beneficial.<\/div>\n<\/details>\n
\nMax bore?<\/summary>\n
Up to 120mm+ with QD bushings on larger tooth counts. Plain bore to approximately 100mm.<\/div>\n<\/details>\n
\nSurface treatment for coastal port use?<\/summary>\n
Hot-dip galvanise or zinc-nickel plating. For extreme marine exposure, SS316 stainless steel.<\/div>\n<\/details>\n
\nMOQ for 4140 24B?<\/summary>\n
One piece with full material certification.<\/div>\n<\/details>\n
