The MR-PINON-DOBLE-1-2-Z12 is a double sprocket with hub, featuring a 1/2" pitch and 12 teeth, machined from SAE 1045 steel. It allows one shaft to drive two chains in parallel, which is useful when you need synchronized strands or a compact reduction in tight spaces.

This sprocket has two toothed rings on a single central hub. The hub sits on the shaft and carries the torque, so check its diameter and fastening method before installation. The 1/2" pitch matches ANSI 40 chain, common in light and medium-duty drives.

You will find this double sprocket in belt and roller conveyors, bucket elevators, packaging lines, woodworking machines, and material handling equipment where two chain strands must run together. Using one double sprocket instead of two single sprockets simplifies mounting and reduces the number of parts on the shaft.

When selecting a sprocket, consider chain pitch, number of teeth, shaft diameter, and hub fastening type. With 12 teeth, this is the smallest size in the 1/2" pitch series. That gives high reduction ratios but also increases the polygonal effect on the chain. During installation, align both chain rings with their respective strands, tension each chain separately, and make sure the hub is centered and axially locked.

To find an equivalent, send the part number of the sprocket you are replacing, along with the number of teeth, chain pitch, and shaft diameter. With that information, we can locate a match in the 1/2" pitch series or evaluate a custom manufacturing option. A photo of the mounted sprocket and the outside diameter measurement also help confirm the number of teeth if you are unsure.
