ANSI #40 Roller Chain Sprocket \u2014 The Most Widely Used ANSI Chain Sprocket<\/h2>\n

The #40 at 1\/2 inch (12.7mm) pitch is the single most specified ANSI roller chain sprocket size worldwide. It covers approximately 40% of all industrial chain drive applications from light packaging machinery to medium-duty conveyor systems. We supply #40 sprockets in simplex (#40), duplex (#40-2), and triplex (#40-3) with tooth counts from 9 to 120 in A-plate, B-hub, C-hub, taper-lock, and QD bushed configurations.<\/p>\n

FAQ<\/h2>\n
\n#40 vs #41?<\/summary>\n
#41 is a lightweight version of #40 with the same pitch but narrower plates and no rollers (bushings only). #40 sprockets are compatible with #41 chain but #41 sprockets should only be used with #41 chain.<\/div>\n<\/details>\n
\n#40 vs ISO 08B?<\/summary>\n
Both 12.7mm pitch but ANSI #40 roller is 7.92mm while ISO 08B roller is 8.51mm. Not interchangeable.<\/div>\n<\/details>\n
\nTaper-lock available?<\/summary>\n
Yes. #40 taper-lock sprockets available across the full tooth count range for rapid installation.<\/div>\n<\/details>\n
\nCast iron #40?<\/summary>\n
Yes. Cast iron #40 for low-speed, high-torque applications where vibration damping is needed.<\/div>\n<\/details>\n
\nMOQ?<\/summary>\n
One piece. #40 is our highest-volume line with extensive stock for rapid dispatch.<\/div>\n<\/details>\n
