The double sprocket 3/8" Z38 is a chain drive sprocket with two tooth rings and a central hub, supplied by MR in SAE 1045 steel. It is used to drive two chains in parallel from the same shaft, keeping the lines synchronized. Its 3/8" pitch and 38 teeth place it in the range of medium drives, where a balance between speed and pulling capacity is sought. It is a part intended for continuous service in industrial equipment.

This item is a double sprocket with hub, 3/8" pitch and 38 teeth (z=38), machined from SAE 1045 steel. The double configuration allows two chains to be mounted on the same body, aligned and locked to the shaft. The central hub provides a bearing surface for the hub and the fastening system. The 3/8" pitch corresponds to roller chains of that pitch, and the number of teeth defines the transmission ratio when combined with another sprocket. MR supplies it with dimensional control on the teeth and the central bore.

Typical applications appear in transmission lines where two branches must be driven at once: roller conveyors, bucket elevators, packaging machines, material handling equipment and drag systems in process plants. It is also used in gear reducers and transmission boxes that require two synchronized outputs. As a part supplied by MR, it can be adapted to specific machining needs within what the process allows.

To select correctly, verify that the chain pitch matches the 3/8" pitch of the sprocket and that the number of teeth is suitable for the desired ratio. Check the shaft diameter and the fastening system (keyway, set screws or taper bushing) before mounting. Alignment between sprocket and chain must be within tolerances to avoid uneven wear. Proper lubrication and correct chain tension extend the life of the teeth.

If you need an equivalent or a nearby size, the most practical thing is to send us the full part number of the sprocket you are replacing, the number of teeth, the pitch and a photo or sketch of the mounting. With that data we can check whether we have a similar part in our supply line or whether it is better to source a variant. We can also guide you on the compatible chain and fastening accessories.
