The double sprocket 3/4" Z38 is a chain drive sprocket with two tooth rings and a central hub, manufactured by EMMAR in SAE 1045 steel. It is used to transmit motion between parallel shafts in industrial equipment, allowing two ratios or two chains on a single body. Its 3/4" pitch and 38 teeth place it in the medium-to-heavy duty drive range.

This item is a double sprocket with hub, 3/4" pitch and 38 teeth, machined in SAE 1045 steel. The commercial designation is Double sprocket 3/4" Z38 and it belongs to the 3/4" pitch series. The design includes two tooth rings integral with a central hub, which allows mounting two chains or duplicating the drive on a single shaft. The SAE 1045 material provides mechanical strength and suitability for surface hardening of the teeth.

Typical applications of a 3/4" pitch double sprocket with 38 teeth are found in chain drives of agricultural machinery, conveyors, chain elevators, material handling equipment and process lines. It is also used in gear reducers and transmission boxes where an additional ratio is needed without adding an extra shaft. In all cases, verify that the chain is of the same pitch and that the number of teeth is compatible with the rest of the system.

To correctly select this sprocket, take into account the chain pitch (3/4"), the number of teeth (38) and the shaft diameter where it is mounted. The hub must accommodate the shaft with the proper fit and the fastening system (key, set screw or taper bushing) must be provided for. Check the alignment between sprockets and the chain tension: a misaligned mounting accelerates wear on the teeth and the chain. If the sprocket runs at high speeds, check the balancing.

If you need an equivalent or a nearby size, the most practical approach is to send us the part number MR-PINON-DOBLE-3-4-Z38 or the data of the original sprocket: pitch, number of teeth, hub diameter and fastening type. With that data we can confirm whether there is a variant in the same series or whether a custom-made part is advisable. We can also evaluate replacement with a single sprocket with hub if the application allows it.
