32B Metric Roller Chain Sprocket \u2014 The Largest Standard ISO Metric Sprocket<\/h2>\n

The 32B at 50.8mm (2 inch) pitch is the largest standard ISO metric roller chain sprocket. Reserved for the most extreme industrial applications where no other single pitch can deliver the required load capacity. Used in large-scale dredging, heavy mining overland conveyors, and steel mill primary drives. Available primarily in simplex (32B-1) from 9 to 57 teeth. 4140 alloy steel is standard for this pitch.<\/p>\n

FAQ<\/h2>\n
\n32B vs ANSI #160?<\/summary>\n
Both 50.8mm pitch. Different roller and width specs. Not interchangeable.<\/div>\n<\/details>\n
\nDuplex available?<\/summary>\n
32B duplex can be manufactured on request for specific tooth counts. Contact us with requirements.<\/div>\n<\/details>\n
\nWhat material is standard?<\/summary>\n
4140 alloy steel is standard for 32B due to the extreme loads this pitch is designed for. C45 available for lower-load applications.<\/div>\n<\/details>\n
\nMax bore?<\/summary>\n
Up to 150mm+ with QD bushings on larger tooth counts. Plain bore to ~120mm.<\/div>\n<\/details>\n
\nMOQ?<\/summary>\n
One piece with full 4140 material cert and dimensional inspection report.<\/div>\n<\/details>\n
