A single-strand sprocket with a 3/8" pitch and 20 teeth, this hub-type unit from MR handles motion transfer on 3/8" pitch roller chains. The hub lets you mount it straight onto a shaft with the right fastening, so no adapter is needed. It suits low and medium speed drives that call for dependable, accurate engagement. SAE 1045 steel gives it solid wear and load resistance for this class of drive.
The code breaks down simply: single strand, 3/8" pitch, 20 teeth (Z20), hub included. It is made from SAE 1045 carbon steel, which balances toughness with wear resistance, making it a practical choice for chain drives. Mounting is direct to the shaft, secured with a set screw or key depending on how the equipment is built.
You will find this sprocket in chain conveyors, farm equipment, packaging lines, lifting systems and general machinery drives. Food processing and process plants also use it where a reliable, easy-to-service drive is needed. Its size and performance profile fit low and medium speed applications with moderate loads.
When selecting it, confirm the chain pitch (3/8"), the tooth count (20) and the shaft diameter at the mounting point. The hub bore must match the shaft and allow a secure fastening. Check alignment with the driven sprocket and set the chain tension correctly. If you need a different ratio, another tooth count in the same pitch will do the job.
For an equivalent, the quickest route is to send part number MR-PINON-SIMPLE-3-8-Z20 or the full designation. You can also provide the pitch, tooth count and required shaft diameter, and we will point you to the right options. Our supplier network lets us offer variants within the same sprocket line.
