24B-2 duplex hub sprockets

24B-2 hub sprockets have two tooth rims and work with duplex 24B-2 chain of 1 1/2" (38.1 mm) pitch to DIN 8187 / ISO 606. This version is for high-torque drives in heavy industry and construction.

24B-2 duplex sprocket - more power and stable seating on the shaft

Two chain strands transmit considerably more power, while the sprocket diameter does not change. The tall hub guides the wide sprocket stably on the shaft, and a long keyway reliably transmits the torque. You bore the hole out for your shaft, and larger sprockets can be chosen in grey cast iron.
