The Disc 1/2" Z12 is a power transmission component supplied by EMMAR Accesorios Industriales. It is a simplex disc without hub, with 1/2" pitch and 12 teeth, machined from SAE 1045 steel. It is designed for building chain drives where a compact sprocket is needed, mounted directly on the shaft or on an adapter bushing. Its hubless design allows it to be integrated into assemblies where space is limited or where fastening is handled by other elements.

This item is a toothed disc with 1/2" pitch and 12 teeth, of the simplex disc without hub type. It is manufactured from SAE 1045 steel, a material that offers good wear resistance and toughness for transmission applications. Since it has no hub, the disc has a central bore that allows mounting on shafts or bushings, and it is secured by key, set screws or similar systems. The designation Disc 1/2" Z12 identifies the 1/2" pitch series with 12 teeth, and it is the reference you will use to order it.

Typical applications of this disc include chain drives in agricultural machinery, conveyors, packaging equipment, automatic doors and linear motion systems. It is also used in the manufacture of gearboxes and mechanisms where a specific transmission ratio is required in a small space. Due to its compact size and hubless mounting, it is common in designs where the sprocket is coupled to a stepped shaft or a bearing support, and a simple and robust solution is needed.

To correctly select this disc, take into account the chain pitch (1/2"), the number of teeth (12) and the central bore diameter, which must match the shaft or bushing where it will be mounted. Also check the type of fastening: if the disc has no hub, you need an additional securing system, such as a key or set screws. During assembly, make sure the disc is aligned with the mating sprocket or toothed wheel to avoid premature wear and noise. Proper chain lubrication extends the service life of the assembly.
