The Browning D50Q45 is a steel, double-strand roller chain sprocket for No. 50 chain with 45 teeth and hardened teeth for extended wear. It uses Browning’s split-taper bushing mounting (Q1) and accepts a bore from 3/4 in to 2-11/16 in; its outside diameter is 9.313 in and its pitch diameter is 8.96 in, enabling secure alignment on compatible shafts and sprockets. This 2-STRAND, 45-tooth sprocket is specifically identified as D50Q45 for No. 50 chain drives, designed for heavy-duty power-transmission applications in industrial equipment that rely on a bushed, split-taper mounting system.
