The simplex sprocket with hub, 1/2" pitch and 40 teeth, is a power transmission component that mounts on the shaft and meshes with the chain to transmit motion. Its hub allows it to be fixed with a set screw or key, depending on the equipment design. It is a part supplied by MR Accesorios Industriales, intended for replacements and transmission assemblies in agricultural, industrial and transport machinery. It is supplied in SAE 1045 steel, a material suitable for machining and subsequent heat treatment if the application requires it.

This item is a simplex sprocket with hub, 1/2" pitch and 40 teeth, supplied in SAE 1045 steel. The designation indicates that it is a single-row toothed wheel with a central hub for shaft mounting. The 1/2" pitch corresponds to the chain it meshes with, and the 40 teeth define the transmission ratio. The hub allows direct mounting on the shaft, with fixing options via screw, key or set screw depending on the equipment design. It is a part supplied by MR.

Typical applications for this sprocket include chain drives in agricultural machinery, conveyors, elevators, machine tools and industrial equipment in general. It is used both in low-speed, high-load drives and in systems requiring a specific transmission ratio. Being made of SAE 1045 steel, it withstands moderate stresses and can be heat treated to increase its wear resistance if the application demands it. It is commonly found in replacements of worn sprockets or in the manufacture of new transmissions.

To correctly select this sprocket, take into account the chain pitch (1/2"), the number of teeth (40) and the shaft diameter where it is mounted. Verify that the hub has the appropriate dimensions for the shaft and the intended fixing system. If the transmission operates with high loads or high speeds, evaluate the need for additional heat treatment. It is also important to check the alignment between sprocket and chain to avoid premature wear. If in doubt, consult our technical team.

If you need an equivalent sprocket or a nearby size, you can send us the item code or the characteristics you are looking for: pitch, number of teeth, hub type and shaft diameter. With that data, we check similar options within the line supplied by MR or evaluate the possibility of sourcing it to measure. We can also advise you on compatibility with chains and other transmission components. The idea is for you to find the part that best suits your equipment.
