This item is a simplex sprocket with hub, 3/4" pitch and 40 teeth (Z40), in SAE 1045 steel. The hub is the central protruding part that allows direct mounting on the shaft, with a bore that is adjusted according to the shaft size. The 3/4" pitch defines the distance between the teeth and must match the chain pitch. It is a part supplied by MR, which facilitates replacement of standard and special sizes.

It is used in chain drives of industrial machines: conveyors, elevators, mixers, packaging equipment and linear motion systems. It is also common in the food, chemical and bulk materials sectors, where a robust drive with simple maintenance is required. Being a sprocket with hub, it simplifies mounting on shafts that do not have a keyway or that need additional fastening with set screws.

To select it, verify that the chain pitch matches the 3/4" pitch of the sprocket and that the number of teeth is suitable for the desired transmission ratio. The hub must have an inner diameter compatible with the shaft and the set screws must remain accessible. Check the alignment between sprocket and chain, and lubricate according to the operating conditions. If the shaft is smaller, a bushing can be machined or the hub adapted, always respecting the SAE 1045 material.
