The Disc 1/2" Z9 is a power transmission component supplied by MR Accesorios Industriales. It is a simplex disc without hub, with 1/2" pitch and 9 teeth, designed to build sprockets or integrate into chain mechanisms. Its SAE 1045 steel construction gives it the strength required for demanding industrial applications. It is a key part for those who need spare parts or components to keep equipment running.
This item is a simplex disc without hub, designated as Disc 1/2" Z9. Its main attributes are: pitch 1/2", number of teeth 9 and material SAE 1045 steel. Since it has no hub, it mounts directly on a shaft or is welded to a hub as required by the mechanism. The 1/2" pitch series is one of the most widely used in chain transmission, and this particular disc, with 9 teeth, offers a specific transmission ratio for applications where a given speed and torque are required.
Typical applications of this disc include the repair of sprockets for 1/2" pitch chains, such as those used in conveyors, agricultural machinery, packaging equipment and motion systems on production lines. It is also used in the assembly of mechanisms where a sprocket with few teeth is needed. Because of its SAE 1045 material, it is suitable for heat treatment and additional machining if the project requires it.
To mount this disc correctly, keep in mind that it must be aligned with the chain and the drive sprocket. The selection depends on the desired transmission ratio and the available space. Since it has no hub, it is essential to verify the shaft diameter and the fastening system (keyway, set screw or welding). If you need a complete sprocket, you can combine this disc with a suitable hub. Always check that the chain pitch matches the disc pitch.
If you are looking for an equivalent, the most practical thing is to send us the part number MR-DISCO-1-2-Z9 or the designation Disc 1/2" Z9 by WhatsApp. You can also tell us the characteristics you need: pitch, number of teeth and mounting type.
