The simplex sprocket with hub, 3/8" pitch and 25 teeth is a power transmission chain wheel that mounts on shafts to drive roller chains. Its hub allows it to be fixed with a set screw or key, depending on the equipment design. MR supplies it in SAE 1045 steel, a material that offers good wear resistance and toughness for continuous service. It is used in conveyors, agricultural machines, elevators and linear motion systems that require a specific transmission ratio.

This item is a simplex sprocket with hub, commercially designated as Simplex sprocket 3/8" Z25. Its construction data are: pitch 3/8", number of teeth 25, material SAE 1045 steel and type simplex sprocket with hub. The hub is the protruding central part that allows mounting on the shaft and fixing by screw, key or both. The 3/8" pitch corresponds to roller chains of that standardized pitch. The number of teeth defines the transmission ratio and the pitch diameter. It is a part supplied by MR, intended for replacement and new projects.

Typical applications of a sprocket of this type include chain drives in belt or roller conveyors, bucket elevators, agricultural machines, packaging equipment and door or gate drive systems. It is also used in gear reducers and transmission boxes where a specific ratio is needed. Being made of SAE 1045 steel, it withstands moderate loads and wear in continuous service, provided that mounting and lubrication are correct. It is an option to replace worn sprockets or to assemble a new 3/8" pitch drive.

To correctly select and mount this sprocket, verify that the chain pitch matches the 3/8" pitch and that the number of teeth is suitable for the desired transmission ratio. Check the shaft diameter and the hub fixing system: set screw, key or both. Check the alignment between sprocket and chain to avoid premature wear. Lubrication must be the one recommended for roller chains. If the sprocket works in a dusty or humid environment, consider additional protections. If in doubt, consult the manufacturer's data sheet or contact MR.

If you need an equivalent sprocket or a nearby size, you can request it by indicating the part number MR-PINON-SIMPLE-3-8-Z25 or the data of the original sprocket: pitch, number of teeth, shaft diameter and hub type. MR can evaluate the supply of sprockets with other numbers of teeth within the same 3/8" pitch or with different hubs. It is also possible to inquire about sprockets of other pitches and materials. To speed up the response, send a photo or a sketch with the main dimensions. The technical team of MR Accesorios Industriales reviews each inquiry and responds with concrete alternatives.
