Industrial D40Q84 Roller Chain Sprocket

Industrial D40Q84 roller chain sprocket from Browning is a double-strand, bushed, split-taper type designed for ANSI #40 roller chain and features 84 teeth for high-torque power transmission. This Browning D40Q84 uses a Q1 split-taper bushing and fits shaft bores from 3/4 in to 2-11/16 in, providing flexible mounting on a range of equipment. The sprocket's outside diameter is 13.66 in (13.663 in) and the pitch diameter is 13.372 in, with 84 teeth evenly spaced for balanced load distribution. Classified as Type 12 double MST in Browning’s catalog, the D40Q84 is a double-sprocket design in steel, intended for rugged industrial drives in power transmission systems requiring a double-strand configuration and a reliable, machined body. This model is the double version of Browning’s 40-tooth family, sharing the same 1/2 in pitch as the rest of the ANSI #40 lineup, and is offered with a split-taper bushing to accommodate common shaft diameters. The part number D40Q84 distinguishes it from single-strand variants and ensures compatibility with standard Browning Q1 bushings for mounting on 3/4 to 2-11/16 in bores.
