The Disc 1/2" Z38 is a sprocket with 1/2" pitch and 38 teeth, supplied by MR in SAE 1045 steel. It is used in chain drives to move shafts, rollers or drag mechanisms in industrial equipment. As a simplex disc without hub, it mounts directly on the shaft or on an adapter hub, which simplifies replacement and drive assembly. It is a part supplied by MR Accesorios Industriales.

This item is a simplex disc without hub, with 1/2" pitch and 38 teeth, machined in SAE 1045 steel. The designation Disc 1/2" Z38 indicates the chain pitch and the number of teeth. It does not include a hub: the disc rests and is fixed on the shaft or on an adapter bushing. SAE 1045 steel allows the teeth to be hardened to improve wear resistance, depending on the intended use.

It is used in chain drives of machines and equipment: conveyors, elevators, mixers, belts and drag systems. It also appears in roller drives, in machines for the food industry and in material handling equipment. As a 38-tooth disc, it is a medium-sized wheel within the 1/2" pitch series, suitable for moderate transmission ratios.

To select the disc, verify that the chain pitch matches the 1/2" pitch and that the number of teeth is the one required by the drive calculation. Check the shaft diameter and the type of fixing: the disc without hub mounts on a hub or directly on the shaft, with key or set screws according to the design. Check the alignment between sprocket and wheel to avoid uneven chain wear.

If you need a nearby size, a disc with a different number of teeth or a version with hub, we can evaluate the supply. We can also analyze a replacement if you send us the shaft dimensions, the chain pitch and the number of teeth of the original disc. The idea is that the new part fits the equipment without modifications and performs the same function.
