This simplex sprocket with hub is identified as Simplex sprocket 1/2" Z22. It is a power transmission part that mounts on a shaft to drive 1/2" pitch chains. The hub is the raised central section that lets you secure the sprocket directly to the shaft with a set screw or key, so no extra bushing is needed. MR Industrial Accessories supplies this sprocket for replacement work and for new transmission builds in industrial equipment.

Key specifications: pitch 1/2", 22 teeth, SAE 1045 steel, simplex sprocket with hub. SAE 1045 is a medium-carbon steel that machines well and can be heat treated later if you need more wear resistance. The hub design simplifies mounting and fastening on the shaft.

Typical uses include 1/2" pitch chain drives that turn shafts on conveyors, elevators, mixers, and other transmission equipment. It is also a common choice when replacing worn sprockets and chains on production lines. Because MR supplies this item, we can source batches in the sizes you require, as long as they are confirmed against a drawing or sample.

To choose the right sprocket, match the chain pitch to the sprocket pitch and pick a tooth count that gives the transmission ratio you need. Check the shaft diameter and decide how you will fasten the sprocket—set screw, key, or both. During installation, align the sprockets and set chain tension following the transmission manufacturer's recommendations. Good lubrication helps the assembly last.

If you need a different tooth count, pitch, or hub size, we can source it. To request an equivalent, send the part number MR-PINON-SIMPLE-1-2-Z22 or the designation Simplex sprocket 1/2" Z22 by WhatsApp, along with your shaft and chain data. You can also send a sample or drawing so we can source to measure.
