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

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 mass 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 number of 12 teeth places it among the small sprockets of the series, ideal for reduction transmission ratios. The commercial designation is Simplex sprocket 1/2" Z12.

It is used in chain transmissions of agricultural machines, conveyors, elevators, belts, mixers and transmission equipment in general. Due to its compact size and its hub, it is common on gearmotor output shafts, in 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 suitable for the ratio you need. The hub must have a compatible shaft diameter and fastening system: it can go with a key, set screw or both, depending on the case. Check the alignment between sprocket and chain, the correct tension and lubrication. SAE 1045 steel can be hardened and tempered to improve wear resistance, depending on use.

If you need an equivalent sprocket or a nearby size, 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 drawing of the original part also works. With that data we verify if we have a close size in the same series or if it is better to source it. We work with standard sizes and with options within our power transmission line.
