Its hub allows it to be mounted directly on the shaft with a keyway, without the need for additional adapters. It is used in equipment requiring a specific transmission ratio with 28 teeth, and its SAE 1045 steel gives it the strength needed for continuous service in plants and workshops.

This item is a simplex sprocket with hub, designated Simplex sprocket 3/8" Z28. Its attributes are: 3/8" pitch, 28 teeth, SAE 1045 steel material and simplex sprocket with hub type. The designation Z28 indicates the number of teeth, and the 3/8" pitch defines the compatible chain. The hub is the central protruding part that allows mounting on the shaft, with a bore that fits the shaft diameter. It is a solid part, machined to withstand the loads of the drive.

Typical applications for this sprocket include chain drives in agricultural machines, conveyors, elevators, packaging equipment and motion systems in industrial plants. Being 3/8" pitch, it is used with chains of that standard pitch, and its 28 teeth offer a transmission ratio that can be combined with other sprockets to obtain the desired speed. It is common on motor output shafts and in mechanisms where movements need to be synchronized.

To correctly mount this sprocket, verify that the shaft diameter matches the hub bore and that the keyway is in good condition. Alignment with the driven sprocket and chain tension are critical to avoid premature wear. Select the number of teeth based on the transmission ratio and available space. SAE 1045 steel accepts surface treatments if greater wear resistance is required, although that must be evaluated according to the application.

If you need an equivalent sprocket or a neighboring size, the most practical thing is to send us the current part number, the number of teeth and the chain pitch. A photo of the part or the shaft diameter also helps. MR Accesorios Industriales manufactures sprockets and chain wheels, so we can adjust to your requirements.
