24B-3 triplex hub sprockets

24B-3 hub sprockets have three tooth rims and run with triplex 24B-3 chain of 1 1/2" (38.1 mm) pitch to DIN 8187 / ISO 606. They are designed for the heaviest drives - mills, rotary kilns, crushers and large conveyors.

24B-3 sprockets - the load capacity of a larger pitch without welding a hub

Three chain strands transmit a torque for which a simplex drive would need a much larger pitch and larger sprockets. A hub sprocket only needs to be bored out for the shaft - no welding or building your own hub. Larger sprockets are also available in grey cast iron.
