This double sprocket with hub runs on 3/4" pitch chain and carries 57 teeth. EMMAR machines it from SAE 1045 steel. Two integral toothed rings share one central hub, so a single shaft position can drive two chain lines or a chain plus an auxiliary mechanism. It suits equipment that runs continuously and needs teeth that hold their shape.

The designation to reference is Double sprocket 3/4" Z57. Three values tell you most of what you need: the 3/4" pitch fixes which chain fits, the 57 teeth set the ratio and the chain speed at the tooth, and the hub is the body that mounts on the shaft. SAE 1045 is a medium-carbon steel that can be hardened and tempered when the duty calls for it.

Typical installations include chain drives on conveyors, bucket elevators, mixers, agricultural machinery and process equipment. The layout also fits low-speed, high-torque drives where one stage has to deliver a large reduction. A keyed shaft takes the hub, and the two rows of teeth let two transmission lines work independently or stay synchronized from the same shaft.

Before ordering, confirm the chain pitch against the 3/4" pitch and check that 57 teeth give the ratio you want. Measure the shaft and identify how the hub is fastened. Keep the sprocket and its mating sprocket aligned; misalignment shows up as uneven tooth wear. During service, watch chain tension and lubrication, since a slack chain wears teeth faster.

Need a different tooth count, or a single sprocket in place of the double? Send the pitch, the number of teeth and the shaft diameter. An equivalent can also be reviewed if you provide the main dimensions and a photo of the part.
