This double sprocket with hub is a toothed wheel with 1/2" pitch and 50 teeth, supplied by MR, manufactured by EMMAR in SAE 1045 steel. It is used to transmit motion between parallel shafts in roller chains, and its double-row design with hub allows mounting it on a shaft and coupling two chains simultaneously. It is a part designed for equipment where it is necessary to synchronize or duplicate the transmission without adding extra components.

The double sprocket 1/2" Z50 from MR is identified by its 1/2" pitch, its 50 teeth and its construction in SAE 1045 steel. The designation "double with hub" indicates that it has two toothed rows integral to a central hub, which allows two chains to work on the same shaft. The 1/2" pitch corresponds to roller chains of that pitch, and the number of teeth defines the transmission ratio when combined with another sprocket of the same pitch.

This type of sprocket is found in agricultural machinery transmissions, conveyors, mixers, elevators and power transmission equipment in general. The double with hub configuration is common in applications where it is required to move two chain lines from the same point, or where it is sought to double the drive capacity without resorting to two independent wheels. It is also used in parallel shaft synchronization systems.

To correctly select a double sprocket, you must verify the chain pitch, the number of teeth, the shaft diameter and the type of fastening (key, set screw or hub with bushing). In this case, the pitch is 1/2" and the teeth are 50, data that comes from the designation. The SAE 1045 material provides wear resistance and toughness, suitable for moderate to high loads. It is important to control the alignment of the two chains and the lubrication to avoid premature wear.

If you need a sprocket with a different number of teeth, another pitch or a nearby size, you can consult us with the part number MR-PINON-DOBLE-1-2-Z50 or with the characteristics shown on the product page. We can also evaluate hub variants or finishes according to your application. The idea is that you send us the data you have about the equipment and we bring you the closest possible alternative.
