Browning HB40A17X58 IDLER Sprocket for No. 40 ANSI chain (1/2 in pitch) with 17 teeth and a 5/8 in bore is a steel, ball-bearing sprocket designed to guide and tension chain in Browning power-transmission assemblies. It has no hub, outer diameter 2.96 in, and pitch diameter 2.721 in, with hardened teeth for wear resistance. This Browning part is intended as an idler in conveyors, machine tools, and other industrial equipment that require precise chain guidance and alignment for No. 40 chain systems, and it matches standard Browning mounting patterns for 17-tooth, 5/8-in-bore sprockets.
