The simplex sprocket 1/2" Z8 is a chain drive sprocket with integrated hub and 8 teeth, marketed by MR in SAE 1045 steel. It is used to transmit motion between parallel shafts in industrial machines and equipment, where a specific transmission ratio and compact mounting are needed. Its 1/2" pitch corresponds to chains of that pitch, and the hub allows securing it to the shaft with a key or set screw. It is a part marketed by MR Accesorios Industriales.
This item is a simplex sprocket with hub, 1/2" pitch and 8 teeth (Z8). It is machined from SAE 1045 steel, a carbon steel with good strength and hardenability, suitable for power transmission. The designation "simplex" indicates a single row of teeth, and the hub is the central part that mounts on the shaft. The 1/2" pitch defines the compatible chain: only chains of that pitch mesh correctly. The 8 teeth give a short transmission ratio, typical of driving or output sprockets.
It is used in chain drives of agricultural machines, conveyors, elevators, mixers and material handling equipment. It also appears in factory implements and drive mechanisms where space is limited and a sprocket with few teeth is needed. Due to its hub, it adapts to shafts with keyway or screw fastening, depending on the equipment design. It is a frequently replaced part in industrial maintenance.
To select it, verify that the chain pitch is 1/2" and that the number of teeth matches the desired ratio. Check the shaft diameter and the hub fastening type: key, set screw or both. The alignment between sprocket and chain must be correct to avoid premature wear. If the sprocket operates at high speeds or loads, consider balancing and lubrication. The hardness of SAE 1045 allows hardening if the service requires it, but that is defined at the factory.
If you need an equivalent or a nearby size, send us the complete part number of the original sprocket, the number of teeth, the pitch and the shaft diameter. With that data we can verify if we have an alternative in the same series or if it is better to source it. We can also guide you on the compatible chain and fastening elements. The more precise the information, the faster we give you a useful answer.

- It uses a 1/2" pitch chain. It is important that the pitch and number of teeth match for correct meshing. If you have doubts, send us the chain part number and we will confirm compatibility.
- Can it be mounted on a shaft of any diameter?
- The hub has an inner diameter that must match the shaft. Since we do not publish hub dimensions on this product page, we ask you to consult us with your shaft diameter to verify the appropriate option.
- Is it domestically manufactured?
- Yes, it is of domestic origin. MR markets it in SAE 1045 steel and we control the main dimensions. If you need special characteristics, we can evaluate an alternative.
