This plain sprocket with hub is a power transmission component that mounts on a shaft and meshes with a chain to transmit motion. The hub allows direct fastening to the shaft with a key or set screws, eliminating the need for additional bushings. It is used in drive systems that require a specific transmission ratio and smooth operation.
Manufactured by EMMAR in SAE 1045 steel, this sprocket has a 3/8" pitch and 40 teeth, making it compatible with chains of that pitch. The built-in hub simplifies direct shaft mounting, and its single-strand design suits standard transmission applications. The SAE 1045 steel provides mechanical strength for moderate loads.
Typical applications include belt or roller conveyors, agricultural machinery, lifting systems, mixers, and other equipment where motion is transmitted between parallel shafts. It is also found in the food, cement, and mining industries when operating conditions are compatible with the material and surface treatment.
When selecting this sprocket, consider the chain pitch (3/8"), the number of teeth (40), and the shaft diameter where it will be installed. Verify that the hub dimensions match the shaft and that the fastening method (key or set screws) is appropriate. Proper alignment of sprockets and correct chain tension per the manufacturer's specifications help prevent premature wear.
If you need a sprocket with a different number of teeth, pitch, or hub size, we can manufacture it. MR Industrial Accessories has in-house machining capability to adapt parts to the requirements of each piece of equipment. To request an equivalent, send us the current code or the dimensions you need, and we will provide a quote promptly.
