This simplex sprocket from EMMAR is built for 3/4" pitch roller chains and carries 43 teeth (Z43). Its hub lets you mount it straight onto a keyed shaft, so no adapter is needed. It suits drives that call for a defined ratio and a solid, serviceable component.

The sprocket is made of SAE 1045 steel, which offers good machinability and mechanical strength for power transmission work. A central bore and keyway in the hub lock it to the shaft and carry torque without extra parts. The single-row layout matches 3/4" pitch roller chains.

You will find this size in chain drives on conveyors, agricultural equipment, lifting gear, machine tools and plant motion systems. It also works for building new equipment or replacing a worn 43-tooth, 3/4" pitch sprocket on an existing line. Under normal service conditions, the SAE 1045 steel handles moderate to high loads, depending on any treatment applied.

When selecting, confirm the chain pitch (3/4"), the tooth count (43) and the shaft diameter. Check that the keyway lines up with the shaft keyway and that the hub length fits the space you have. Align the sprockets and set chain tension to the manufacturer's specification to limit premature wear. If you need another ratio, we can source the size for you.
