This item is a double sprocket with hub, manufactured by EMMAR in SAE 1045 steel, with 1/2" pitch and 39 teeth. The designation Double sprocket 1/2" Z39 indicates that it is a part for a 1/2 inch pitch chain, with 39 teeth, and that it incorporates a hub for mounting on a shaft. SAE 1045 material is a carbon steel with good machinability and strength, suitable for power transmission under moderate to high load conditions.

Typical applications of this sprocket include chain conveyors, elevators, agricultural machinery, packaging equipment and transmission systems in industrial plants. Being 1/2" pitch and 39 teeth, it is used in ratios where the aim is to reduce the speed of the driven shaft or increase torque, depending on the combination with the drive sprocket. It is also used in synchronization mechanisms and in production lines that require chain drive.

To correctly select this sprocket, take into account the chain pitch (1/2"), the number of teeth (39) and the diameter of the shaft where it is mounted. The hub allows fastening it with set screws or a key, depending on the equipment design. Verify the alignment between sprockets and the chain tension to avoid premature wear. If you need a different number of teeth or a different pitch, a neighboring size or an equivalent can be evaluated.
