This simplex sprocket from MR is a 3/8" pitch, 27-tooth (Z27) toothed wheel with a hub, made from SAE 1045 steel. It transfers motion in 3/8" pitch chain drives where a 27-tooth ratio is required, such as light conveyors, agricultural equipment and light-duty drive systems.

The sprocket is built from SAE 1045 steel, a grade known for solid mechanical strength and suitability for hardening. Its hub design lets you mount it on a shaft with a keyway or secure it with screws, depending on how the equipment is arranged. As the chain engages the teeth, the sprocket converts that movement into shaft rotation, and the transmission ratio is set by the tooth count.

You will find this sprocket in chain drives on agricultural machinery, belt or roller conveyors, packaging lines and motion systems in industrial plants. It also appears in machine tools and equipment that need speed reduction or multiplication with low maintenance. Its sturdy build suits moderate loads and medium speeds, provided lubrication is kept up.

When choosing this sprocket, confirm the chain pitch (3/8"), the tooth count (27) and the shaft diameter it will sit on. Check that sprocket and chain are aligned, and use a tensioner or guide to avoid skipping. The hub simplifies mounting, but verify the keyway matches the shaft. If you need a different bore diameter or added heat treatment, let us know.

For a replacement, the simplest approach is to send the complete part number of the sprocket you are replacing, or the shaft and chain dimensions. With that information we can suggest alternatives in the same 3/8" pitch series or look at a custom build. MR manufactures this type of part, so machining can be adjusted to your requirements.
