The double sprocket 3/8" Z39 is a chain drive sprocket, supplied by MR, in SAE 1045 steel. It is used to transmit motion between parallel shafts, with two tooth rings integral with a central hub that allows mounting on a shaft. Its 3/8" pitch and 39 teeth place it in medium-duty drive applications, where a balance between speed and pulling capacity is sought.

This item is a double sprocket with hub, 3/8" pitch and 39 teeth (z=39), machined in SAE 1045 steel. The designation double sprocket indicates that it has two tooth rings in a single part, with a central hub that serves as support and fastening to the shaft. The 3/8" pitch defines the compatible chain, and the number of teeth determines the drive ratio when combined with another wheel. The hub allows mounting it directly on the shaft, with the usual fastening systems.

It is used in chain drives of agricultural machinery, conveyors, lifting equipment and production lines. It is common in applications where a motion output needs to be duplicated or the direction of rotation reversed by means of a single component. It also appears in gear reducers and transmission boxes that require two different ratios on the same shaft. Its SAE 1045 steel construction gives it wear resistance in continuous service with moderate loads.

To select it, verify that the chain pitch matches the 3/8" pitch of the sprocket and that the number of teeth is suitable for the desired drive ratio. The hub must have a diameter and fastening system compatible with the shaft. Check the alignment between sprocket and chain, and the axial play. During mounting, lubricate the chain and check the tension; excessive tension accelerates wear on teeth and bushings.

If you need a nearby size, a different number of teeth or a single sprocket instead of a double one, tell us the pitch, the number of teeth and the required hub diameter. We can also evaluate material or treatment variants. To do so, send us the part number MR-PINON-DOBLE-3-8-Z39 or the full designation by WhatsApp and we will quote the option that best fits your equipment.
