Tritan 40BS30H Sprocket for Chain Drive Systems

This Tritan 40BS30H sprocket is a finished-bore transmission component designed for single-strand 40 chain pitch. It suits maintenance technicians and machinery builders who need a direct replacement with a fixed 3/4 in bore and integrated keyway.

Installation uses the included set screws and keyway

The sprocket arrives with two set screws and a 3/16 in wide by 3/32 in deep keyway already machined. Alignment on the shaft is straightforward, though the 0.716 in hub projection requires adequate axial clearance on the driven equipment.

Chain pitch and tooth count set the mechanical

The 1/2 in pitch and 30-tooth configuration fix the speed ratio and engagement geometry for 40 chain. A 5.06 in outside diameter and 4.783 in pitch diameter define the space envelope, so the assembly cannot accommodate larger chain sizes or different strand counts.
