ANSI #100 \u2014 Extra-Heavy-Duty 1-1\/4″ Pitch<\/h2>\n

The #100 at 1-1\/4 inch (31.75mm) pitch is designed for extra-heavy-duty applications where #80 capacity is exceeded. Used on the largest mining conveyors, steel mill drives, cement kiln mechanisms, and heavy port ship-loading equipment. Simplex (#100), duplex (#100-2), triplex (#100-3) from 9 to 100 teeth.<\/p>\n

FAQ<\/h2>\n
\n#100 vs ISO 20B?<\/summary>\n
Both 31.75mm pitch but different roller and width specs. Not directly interchangeable.<\/div>\n<\/details>\n
\nWhen to use #100 over #80 duplex?<\/summary>\n
#100 simplex provides similar capacity to #80 duplex in a narrower hub width. Choose when shaft width is limited.<\/div>\n<\/details>\n
\nMax bore?<\/summary>\n
Up to 110mm+ with QD bushings. Plain bore to ~90mm on larger tooth counts.<\/div>\n<\/details>\n
\nSurface treatment for coastal?<\/summary>\n
Hot-dip galvanise or zinc-nickel. For marine submersion, SS316 stainless available on request.<\/div>\n<\/details>\n
\nMOQ?<\/summary>\n
One piece with material cert.<\/div>\n<\/details>\n
