The double sprocket with hub, 1/2" pitch and 19 teeth, is a power transmission component that mounts on shafts to transmit motion through chains. Its double-row design allows it to drive two chains in parallel, synchronizing mechanisms or doubling the drive capacity. Sold by MR in SAE 1045 steel, it is a robust and versatile part for a wide variety of industrial and agricultural applications.
This item is a double sprocket with hub, designated as Double sprocket 1/2" Z19. Its technical attributes are: pitch 1/2", number of teeth 19 (z), material SAE 1045 steel and type double sprocket with hub. The hub allows it to be fixed to the shaft by means of a key or a set screw, depending on the design. The 1/2" pitch corresponds to standard roller chains, and the 19 teeth define the transmission ratio. It is a part sold by MR Accesorios Industriales.
Typical applications include chain drive systems in agricultural machinery, conveyors, elevators, mills, mixers and industrial equipment in general. Because it is double, it is used when two chains need to be moved simultaneously, for example on drive shafts with two branches, or to increase load capacity while keeping a single shaft. It is also common in agricultural implements that require synchronized movements.
To correctly select this sprocket, check that the chain pitch matches the 1/2" pitch and that the number of teeth is suitable for the desired transmission ratio. The hub must have a compatible shaft diameter and fixing system. During mounting, ensure alignment between sprocket and chain to avoid premature wear. Lubrication and correct chain tension are key to a long service life.
