The simplex sprocket 3/8" Z13 is a chain sprocket supplied by MR Accesorios Industriales, designed to transmit motion in 3/8" pitch chains. Its hub allows it to be mounted directly on the shaft, and its 13 teeth make it ideal for drive ratios where speed rather than force is sought. It is supplied in SAE 1045 steel, a material that resists wear well in continuous service.

This item is a simplex sprocket with hub, with 3/8" pitch and 13 teeth (Z13). The pitch indicates the distance between chain roller centers, and the 13 teeth define the drive ratio. The hub is the central part that mounts on the shaft, and the material is SAE 1045 steel, suitable for general mechanical applications. MR supplies it with dimensional control so that it engages correctly with 3/8" pitch chains.

It is used in low- and medium-power chain drives: light conveyors, agricultural machinery, packaging equipment, automatic doors and linear motion mechanisms. It also appears in gearboxes and lifting systems where a compact sprocket that saves space is needed. Being a 13-tooth sprocket, it is common as the small wheel in the drive, where the goal is to increase the speed of the driven shaft.

To mount it, verify that the shaft diameter matches the hub bore and that the key fits without play. Alignment with the driven sprocket is key: angular or parallel misalignment accelerates wear on teeth and chain. Check chain tension according to the equipment manual. If the sprocket works in a dirty environment, consider a suitable lubricant and a seal if the hub allows it.

If you need a nearby size, such as a different number of teeth or a different pitch, or if you are looking for an equivalent from another brand, send us the full part number via WhatsApp. We can also help if the original sprocket has no visible brand: with the pitch, the number of teeth and the shaft diameter we can identify the corresponding option within our supply line.

MR Accesorios Industriales supplies this sprocket and a broad power transmission line.
