The double sprocket 1/2" Z45 is a power transmission component that MR supplies in SAE 1045 steel. It is used to transmit motion between parallel shafts by means of a 1/2" pitch chain, with 45 teeth and an integrated hub. It is a part designed for standard roller chains, where a specific transmission ratio and firm shaft attachment are required. Its carbon steel construction allows the shaft bore and fixing holes to be machined according to the application.

This item is a double sprocket with hub, 1/2" pitch and 45 teeth, in SAE 1045 steel, supplied by MR. The designation Double sprocket 1/2" Z45 indicates that it is a sprocket for 1/2-inch pitch chain, with 45 teeth and a central hub that allows direct mounting on the shaft. SAE 1045 material is a carbon steel with good machinability and strength, suitable for parts subjected to moderate stresses. The hub facilitates boring the hole and fitting a keyway or set screws as required by the equipment.

Typical applications of this sprocket include chain drives in agricultural machinery, conveyors, bucket elevators, mixers and industrial equipment in general. It is also used in parallel-shaft motion systems where a transmission ratio determined by the number of teeth is required. MR supplies this sprocket and can source variants with hub machining adapted to match the equipment shaft diameter and length, provided those dimensions are indicated at the time of inquiry.

To correctly select this sprocket, take into account the chain pitch (1/2"), the number of teeth (45) and the shaft diameter where it is mounted. The hub allows fixing with a key, set screws or fixing screw, depending on the design. It is important to verify alignment between sprockets and chain tension to avoid premature wear. If the shaft has a standard diameter, it can be supplied with the bore machined to size; if not, it is recommended to send a sketch or the exact dimensions.

If you need a sprocket with a different number of teeth, another pitch or a hub with different dimensions, MR can source it. To request an equivalent or a nearby size, send the part number MR-PINON-DOBLE-1-2-Z45 or the data of the original sprocket: pitch, number of teeth, shaft diameter and type of fixing. With that data, sourcing a similar part or adapting the hub machining can be evaluated. They can also be combined with ANSI chains and other transmission components that MR supplies.
