The MR-PINON-SIMPLE-3-8-Z25 is a single-strand sprocket with a hub, built for roller chains with a 3/8" pitch. It has 25 teeth and is made of SAE 1045 steel. The hub is the raised center section that fits onto a shaft and can be secured with a set screw, a key, or both, depending on how the equipment is designed. This sprocket is used in conveyors, agricultural machinery, elevators, and linear motion systems where a particular drive ratio is required.

Key specifications for this sprocket: pitch 3/8", tooth count 25, material SAE 1045 steel, and type simplex with hub. The 3/8" pitch matches standard roller chains of that size. The number of teeth sets the transmission ratio and the pitch diameter. The hub allows the sprocket to be mounted on a shaft and locked in place. This is a replacement part and can also be used in new builds.

Common uses for a sprocket like this include chain drives on belt or roller conveyors, bucket elevators, farm equipment, packaging lines, and gate or door operators. It also appears in gear reducers and transmission boxes that need a specific ratio. SAE 1045 steel gives it good resistance to wear and moderate loads in continuous operation, as long as it is installed and lubricated correctly. It is an option for replacing a worn sprocket or setting up a new 3/8" pitch drive.

When choosing and installing this sprocket, confirm that the chain pitch is 3/8" and that 25 teeth suit your desired ratio. Check the shaft diameter and how the hub will be fixed: set screw, key, or both. Make sure the sprocket and chain are aligned to prevent uneven wear. Use the lubricant recommended for roller chains. In dusty or damp conditions, consider adding protection. If you are unsure, ask MR for guidance.
