This simplex sprocket with hub, 1/2" pitch and 18 teeth, is a sprocket supplied by MR Accesorios Industriales. It is used to transmit motion between parallel shafts by means of a roller chain, within the speed and load range corresponding to that pitch. The hub allows it to be mounted on the shaft with a key and screw, without the need for additional adapters. It is a replacement part and also used for assembling new drives.

The simplex sprocket 1/2" Z18 has a 1/2" pitch, 18 teeth, SAE 1045 steel material and simplex type with hub. That combination of pitch and number of teeth defines the pitch diameter and the transmission ratio when it is combined with another sprocket of the same chain. The hub is the central part that allows direct mounting on the shaft. SAE 1045 steel is a medium-carbon material, suitable for machining and for heat treatment according to the requirements of the application.

It is used in 1/2" pitch chain drives in agricultural machinery, conveyors, packaging equipment, production lines and drive mechanisms in general. It also appears in the assembly and repair of gearboxes and transmission cases that work with that pitch. As a part supplied by MR, it can be replaced with the same geometry as the original or adapted to a specific machine requirement.

To select it, take into account the chain pitch, the number of teeth, the shaft diameter where it is mounted and the type of fastening (key, screw, set screw). Check that the chain is compatible with the 1/2" pitch and that the desired transmission ratio is achieved with the available combination of sprockets. If the shaft has a different diameter than the hub, a bushing can be machined or the hub modified, always from a drawing or sample.

If you need an equivalent or a nearby size, send us the part number MR-PINON-SIMPLE-1-2-Z18 or the full designation on WhatsApp. You can also send a photo of the part, the pitch, the number of teeth and the shaft diameter. With that data we confirm whether there is a standard size that replaces the current one or whether it is better to order a custom part. We work with drawings and samples for transmission parts.
