The plain sprocket with hub, 3/8" pitch and 40 teeth is a power transmission component that mounts on the shaft and meshes with the chain to transmit motion. Its hub allows it to be fastened directly to the shaft, either with a key or with set screws, without the need for additional bushings. It is a key part in drive systems where a specific transmission ratio and smooth running are required.
This item is a plain sprocket with hub, supplied by MR in SAE 1045 steel. It has a 3/8" pitch and 40 teeth, which makes it suitable for chains of that pitch. The built-in hub facilitates direct mounting on the shaft, and its single-strand design orients it toward standard transmission applications. The SAE 1045 steel gives it mechanical strength suitable for moderate loads.
It is used in a wide variety of industrial equipment: belt or roller conveyors, agricultural machinery, lifting systems, mixers and other machines where motion needs to be transmitted between parallel shafts. It is also common in the food, cement and mining industries, provided that the operating conditions are compatible with the material and the surface treatment.
To correctly select this sprocket, take into account the chain pitch (3/8"), the number of teeth (40) and the shaft diameter where it will be mounted. Check that the hub has the right dimensions for the shaft and that the fastening system (key or set screws) is the appropriate one. It is advisable to perfectly align the sprockets and tension the chain according to the manufacturer's specifications to avoid premature wear.
If you need a sprocket with a different number of teeth, a different pitch or a different hub size, we can look for another size in the line or a compatible alternative. MR Accesorios Industriales supplies these parts and can help you find the right one for your equipment. To request an equivalent, simply send us the current code or the dimensions you need and we will quote you shortly.
