The simplex sprocket with hub, 1/2" pitch and 39 teeth is a power transmission component that mounts on the shaft and meshes with 1/2" pitch chains. Its integrated hub allows it to be fastened directly to the shaft, without the need for additional bushings. Supplied by MR in SAE 1045 steel, it is designed for industrial applications that require strength and durability. It is a key part in motion systems where torque must be transmitted reliably.

This item is a simplex sprocket with hub, designated as Simplex sprocket 1/2" Z39. Its main attributes are: pitch 1/2", number of teeth 39, material SAE 1045 steel and type simplex sprocket with hub. The hub is the central protruding part that allows direct mounting on the shaft, with a bore that fits the shaft diameter. SAE 1045 steel is a medium-carbon steel, suitable for parts subjected to moderate and high mechanical stresses.

Typical applications of this sprocket include chain drives in agricultural machinery, conveyors, lifting systems, packaging equipment and production lines in general. Being 1/2" pitch, it is compatible with chains of that pitch, such as ANSI 40 chains or equivalents. It is used both in new assemblies and as a replacement for worn sprockets, as long as the number of teeth and the pitch are maintained to keep the original transmission ratio.

To mount this sprocket correctly, check that the shaft diameter matches the hub bore and that the key or fastening system is in good condition. It is important to align the sprocket with the rest of the transmission components to avoid premature wear. When selecting, take into account the power to be transmitted, the rotation speed and the environmental conditions. If you need a different ratio, you can choose another number of teeth within the same pitch.

If you are looking for an equivalent or a nearby size, the most practical thing is to send us the part number MR-PINON-SIMPLE-1-2-Z39 or the data of the original sprocket: pitch, number of teeth, shaft diameter and hub type. With that information we can identify the right part or suggest a compatible alternative. We can also advise you if you need to modify the bore or add surface treatments.
