The simplex sprocket with hub, 1/2" pitch and 42 teeth is a power transmission component that mounts on the shaft and meshes with 1/2" pitch chains. Its hub allows it to be fixed with a set screw or key, and its SAE 1045 steel gives it wear resistance. It is used in agricultural machinery, conveyors, packaging lines and material handling equipment. MR supplies it in Argentina through its distribution network.
This item is a simplex sprocket with hub of 1/2" pitch and 42 teeth, made of SAE 1045 steel. The designation Simplex sprocket 1/2" Z42 indicates that it has a single row of teeth and that its pitch diameter corresponds to 42 teeth. The hub is the central part that protrudes and allows mounting on the shaft, with space for a set screw or a key. It is a power transmission part used with 1/2" pitch chains. MR Accesorios Industriales supplies it in the country, with dimensional control to ensure correct meshing.
Typical applications of this sprocket include agricultural machinery, chain conveyors, bucket elevators, packaging lines and material handling equipment. It is also found in low and medium speed drive systems where a specific transmission ratio is required. Being made of SAE 1045 steel, it withstands moderate loads and friction wear. It is common to see it on gearmotor output shafts or on intermediate shafts of machine tools.
To select and mount this sprocket, take into account the chain pitch (1/2"), the number of teeth (42) and the shaft diameter where it is mounted. The hub must match the shaft diameter and the fixing system must be suitable for the load. Verify alignment between sprocket and chain to avoid premature wear. Lubrication and chain tension are key to service life. If you need a different ratio, we can look for another sprocket with a different number of teeth within our line or a compatible alternative.
If you are looking for an equivalent, the most practical thing is to send us the exact code of the sprocket you need to replace or the shaft and chain measurements. With that data we can identify the part or suggest an alternative from our product line. We can also advise you on the type of steel and heat treatment according to the application. Do not hesitate to ask us about variants in the number of teeth or hub diameter available in our line.

Frequently Asked Questions
- What does it mean that it is a simplex sprocket with hub?
- It means that it has a single row of teeth and a central hub that protrudes to mount it on the shaft. The hub allows it to be fixed with a set screw or key, unlike flat sprockets that mount directly on the shaft.
- Is this sprocket suitable for 1/2" pitch chains?
- Yes, it is designed to mesh with 1/2" pitch chains. It is important to verify that the chain is of the same pitch and that the number of teeth matches the desired transmission ratio. If you have doubts, ask us with the chain code.
- Can I order a sprocket with a different number of teeth?
- We can look for another sprocket with a different number of teeth within the 1/2" pitch line. If you need a different transmission ratio, send us your shaft measurements and the required number of teeth, and we will suggest a compatible alternative from our line.
