Browning DS40H21 Sprocket

Browning DS40H21 is a double-single (DS-1) steel roller chain sprocket for 40-chain drives, built with hardened teeth and a Browning split-taper bushing (H-size) for easy shaft mounting. It has 21 teeth, an outside diameter of 3.6170 inches, a pitch diameter of 3.3548 inches, and a bore range from 3/8 to 1-1/2 inches with a hub diameter of 2.4940 inches, designed to accommodate two strands across. Weighing about 2.00 pounds, this single-pitch sprocket is part of Browning's bush-type line that uses the H bushing for installation and compatibility with 40-chain systems. The DS40H21's robust steel construction and hardened teeth are engineered for durable power transmission in industrial equipment that uses 40-pitch chain and Browning split-taper bushings.
