The double sprocket 1/2" Z31 is a chain wheel supplied by MR Accesorios Industriales, designed to transmit motion in 1/2" pitch chains. It has 31 teeth and a hub, and is machined from SAE 1045 steel. It is used in power transmissions where two chain strands need to be driven or two chain rings mounted on the same shaft. If you need to replace a worn sprocket or build a new transmission, this part number is a good starting point.

This item is a double sprocket with hub, 1/2" pitch and 31 teeth (z=31), machined from SAE 1045 steel. The designation Double sprocket 1/2" Z31 indicates the chain pitch and the number of teeth; the hub is the central part that allows it to be fixed to the shaft. The double body allows two chains to be mounted in parallel on the same part, which is common when the drive needs to be duplicated without adding a second sprocket to the shaft.

It is used in chain drives in agricultural machinery, conveyors, chain elevators, material handling equipment and production lines. It also appears in older or domestically manufactured machines where the exact replacement is not available and a part has to be adapted. Being made of SAE 1045 steel, it is a sprocket suitable for continuous service with proper lubrication and for heat treatment if the application requires it.

To select it correctly, check that the chain pitch is 1/2" and that the 31 teeth match the desired transmission ratio. Check the shaft diameter and the hub fastening system (keyway, set screws or bushing). If the original sprocket has a different number of teeth, changing it alters the ratio: ask us and we will help you evaluate the closest size that best fits your machine.

If you cannot find the exact part number, send us a photo or a sketch with the main dimensions: pitch, number of teeth, hub diameter and type of fastening. With that data we can offer you an equivalent from our sprocket line or evaluate in-house manufacturing of a custom part. We also work with ANSI chains and other transmission components so you can solve the complete drive in a single inquiry.
