This 1/2" pitch simplex sprocket with 27 teeth is a power transmission part that fits onto a shaft and engages a chain of the same pitch. The hub is built into the sprocket, so it can be fixed with a key, a set screw, or both, depending on how the machine is designed. EMMAR produces it in SAE 1045 steel. You will find it in conveyors, packaging lines, agricultural equipment and other drives that need a set ratio.

The commercial designation is Simplex sprocket 1/2" Z27, and the part number is MR-PINON-SIMPLE-1-2-Z27. It belongs to the 1/2" pitch series and runs with standard chains of that pitch. Because the hub is part of the same piece, you can mount it straight on the shaft without adding a separate bushing. EMMAR makes it in SAE 1045 steel, which offers a tough core and a surface that stands up to chain contact.

Typical uses include chain drives on belt and roller conveyors, bucket elevators, food processing machines, farm implements and plant drive systems. It also works on test benches and prototypes where the ratio may need to change. The solid, simple construction suits areas with dust, moderate humidity or light shock, as long as lubrication is maintained.

When selecting, confirm the chain pitch is 1/2" and that 27 teeth give the ratio you need. Check that the hub bore and fastening method (keyway, set screw or both) match your shaft. Align the sprockets and set chain tension following the drive manufacturer's instructions. Our team can help you choose if you are unsure.
