This duplex sprocket, identified as MR-PINON-DOBLE-3-8-Z18, is a chain wheel with an integral hub. It is designed to be mounted on a shaft and to transmit motion through 3/8" pitch chains. The duplex configuration means two chain rings share the same hub, which allows a single component to drive two chains at once. Made from SAE 1045 steel, it provides strength and durability for demanding industrial use. This design simplifies assembly and reduces the number of parts needed in systems that require two chain rings on one shaft.

The sprocket has 18 teeth and a 3/8" pitch. Its duplex construction means two sets of teeth are mounted on a common hub, so it can transmit motion to two chains simultaneously or double the transmission capacity within one part. The integrated hub allows direct mounting on the shaft, eliminating the need for separate bushings or adapters.

Typical uses include chain drives in agricultural machinery, conveyors, lifting equipment, and industrial production lines. The 3/8" pitch is common in medium-power transmissions where an 18-tooth ratio is required. Because it is duplex, it suits setups that need to synchronize two movements or drive two distant shafts from one point, saving space and reducing component count.

When selecting this sprocket, consider the chain pitch (3/8"), the number of teeth (18), and the shaft diameter for the hub. Make sure the chain and mating sprockets share the same pitch and that alignment is correct to prevent premature wear. SAE 1045 steel offers a balance of mechanical strength and machinability, though surface treatments may be needed depending on the application. During installation, ensure secure fastening and proper lubrication to extend service life.

If you need a different tooth count, pitch, or a special configuration, we can manufacture it. MR Industrial Accessories LLC has machining capacity to adapt sizes and materials to your requirements. To request an equivalent, send the current part number or technical details (pitch, teeth, shaft diameter, etc.) and we will quote a made-to-measure solution. We can also advise on the best option for your specific application.
