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

This item is a double sprocket with hub, 3/8" pitch and 38 teeth (z=38), machined in 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 bore and the fastening system. The 3/8" pitch corresponds to roller chains of that pitch, and the number of teeth defines the drive ratio when combined with another sprocket. MR sells it with dimensional control on the toothing and the central bore.

Typical applications appear in drive 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, check that the chain pitch matches the 3/8" pitch of the sprocket and that the number of teeth is suitable for the ratio you need. Check the shaft diameter and the fastening system (keyway, set screws or taper bushing) before mounting. Alignment between sprocket and chain must stay within tolerances to avoid uneven wear. Proper lubrication and correct chain tension extend the life of the toothing.

If you need an equivalent, 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 assembly. With that data we can point you to the similar part in our product line or source a variant. We can also advise you on the compatible chain and fastening accessories.
