The simplex sprocket with hub, 5/8" pitch Z31, is a power transmission sprocket that mounts on the shaft and meshes with the chain to transmit motion. Its hub allows it to be secured with a set screw or key without additional bushings. It is a part supplied by MR Accesorios Industriales, designed for replacements and transmission assemblies in agricultural, industrial and transport machinery.

This sprocket has a 5/8" pitch, 31 teeth (Z31) and is manufactured in SAE 1045 steel. It is simplex with hub, meaning the teeth are machined on a body with a central hub for direct mounting on the shaft. The 5/8" pitch corresponds to roller chains of that pitch, and the number of teeth defines the transmission ratio and tangential speed. The hub provides a bearing surface and allows the sprocket to be secured with a set screw or key according to the shaft design.

It is used in chain drives in agricultural machinery, conveyors, elevators, mills, mixers and material handling equipment. It also appears in trailing implements, seeders and harvesters, where a specific transmission ratio is required. Being made of SAE 1045 steel, it withstands moderate loads and contact wear, and is suitable for surface treatments if greater durability is required.

To select it, verify that the chain pitch matches the 5/8" pitch of the sprocket and that the number of teeth is appropriate for the desired transmission ratio. Check the shaft diameter and the hub fastening system: set screw, key or both. Check the alignment between sprocket and chain, tension and lubrication. Misaligned mounting or excessive tension shortens the life of the teeth and the chain.

If you cannot find the sprocket with the exact number of teeth, we can evaluate a neighboring size or an equivalent that maintains the pitch and hub type. For that, send us the part number, pitch, number of teeth, shaft diameter and a photo or sketch of the part. With that data we verify alternatives within our supply line or from the brands we carry.

MR Accesorios Industriales supplies this sprocket as well as bearings, housings, chains and power transmission.
