Its hub allows direct mounting on shafts, and its 38 teeth place it in the medium ratio range. It is used in mechanisms requiring moderate reduction with good engagement and durability. If you need to replace a worn sprocket or build a new transmission, this model is quoted via WhatsApp with the code MR-PINON-SIMPLE-3-8-Z38.
This item is a simplex sprocket with hub, designated as Simplex sprocket 3/8" Z38. Its construction data are: pitch 3/8", 38 teeth (z), material SAE 1045 steel and type simplex sprocket with hub. The hub is the central protruding part that allows mounting on the shaft, unlike flat plate sprockets. SAE 1045 steel is a medium-carbon material, suitable for machining and heat treatment, which gives it a wear-resistant base for continuous service.
Typical applications of a 3/8" pitch sprocket with 38 teeth include chain drives in agricultural machinery, conveyors, packaging equipment, automatic doors and light lifting mechanisms. It is also found in power transmission systems where an intermediate reduction ratio between the driving sprocket and the driven wheel is sought. Due to its size and number of teeth, it is common on gearmotor output shafts and intermediate shafts of machine tools.
To correctly select this sprocket, take into account the chain pitch, the number of teeth of the complementary sprocket, the center distance and the diameter of the shaft on which it is mounted. The hub must have the appropriate bore and keyway for the shaft; if they do not match, a bushing can be machined or the hub adapted. Also check the alignment between sprockets and the chain tension, because misaligned mounting accelerates wear on teeth and chain.
If you need an equivalent or a nearby size, the most practical thing is to send us the current code, a photo of the sprocket and the shaft and pitch measurements. We can also evaluate whether a plate sprocket is preferable to one with a hub, depending on the space available in the equipment.

Frequently Asked Questions
- What does it mean that it is simplex with hub?
- It means it has a single row of teeth and a central protruding hub, which allows direct mounting on the shaft with a keyway. It is not a flat plate sprocket; the hub provides a larger support surface.
- Can I request a different number of teeth for the same pitch?
- Yes, within the 3/8" pitch line we can offer other numbers of teeth. Send us the current code and the shaft measurements so we can find the variant that best suits your equipment.
