MR supplies the double sprocket 3/4" Z20, a toothed wheel with two rings on a single body and a central hub. It is made of SAE 1045 steel and is designed for 3/4" pitch chains. This configuration lets you drive two chains from one shaft, which reduces the number of parts and simplifies alignment. To request a quote, send the part number by WhatsApp or email.

The designation Double sprocket 3/4" Z20 tells you the key details: 3/4" is the chain pitch it matches, Z20 means 20 teeth, and double indicates two toothed rings share the same body. The hub is the central boss that mounts on the shaft. With 20 teeth, you can calculate the transmission ratio for your setup. The part is machined in SAE 1045 steel.

You will find double sprockets in agricultural drives, conveyors, bucket elevators, mixers and material handling systems. The two rings let you run two chains in parallel or send power to two branches from one point. This is useful when space is tight and you want fewer components. Gearboxes and transmission cases with a double output also use them.

Before ordering, check that your chain pitch is 3/4" and that 20 teeth give the ratio you need. Confirm the shaft diameter and how the hub will be fastened. Make sure the overall width of the double sprocket fits your available space. During installation, align both rings with their chains and set the tension correctly to avoid wear. If SAE 1045 steel does not suit your application, ask about other options.
