This simplex sprocket with hub, 1/2" pitch and 12 teeth, is an SAE 1045 steel sprocket that transmits motion in roller chains. It is used in power transmissions where a compact and sturdy gear is needed, with the hub already integrated for mounting on the shaft. It is a part designed for replacement and for building new transmissions.

The simplex sprocket 1/2" Z12 has a 1/2" pitch, 12 teeth and is manufactured in SAE 1045 steel. It is a simplex sprocket with hub: the central hub is part of the piece and allows it to be mounted directly on the shaft, without the need for a separate disc. The 1/2" pitch corresponds to roller chains of that pitch, and the 12-tooth count places it among the small sprockets of the series, ideal for transmission ratios with reduction. The commercial designation is Simplex sprocket 1/2" Z12.

It is used in chain transmissions of agricultural machinery, conveyors, elevators, belts, mixers and transmission equipment in general. Due to its compact size and its hub, it is common on gearmotor output shafts, on roller drives and in mechanisms where radial space is limited. It is also used as a drive sprocket in 1/2" pitch chains and in assemblies where a specific transmission ratio with few teeth is sought.

To select it, verify that the chain pitch matches the 1/2" pitch of the sprocket and that the number of teeth is adequate for the ratio you need. The hub must have a shaft diameter and fastening system that are compatible: it can go with a keyway, set screw or both, depending on the case. Check the alignment between sprocket and chain, the correct tension and the lubrication. SAE 1045 steel can be hardened and tempered to improve wear resistance, depending on the use.

If you need an equivalent sprocket, send us the full part number, the number of teeth, the pitch and the hub dimensions (shaft diameter, width and type of fastening). A photo or a drawing of the original part also works. With that data we propose an option in the same series or we source it. We work with standard sizes and with options within our power transmission line.
