A single-row sprocket built from SAE 1045 steel, this 1/2" pitch, 11-tooth (z=11) unit comes with a hub so it can sit on a shaft and be locked down with a key or set screws, whichever suits the machine. It fits chain drives that call for a compact sprocket with a low tooth count, working either as the driver or the driven element. MR Industrial Accessories supplies it for both replacement jobs and new builds.

Reading the designation: "simplex" tells you there is one row of teeth, "1/2\"" is the chain pitch it mates with, and "Z11" is the tooth count. The hub at the center is what carries the bore and keyway for shaft mounting. When paired with a larger sprocket, those 11 teeth set the ratio between the two. This is a part MR distributes for integration into chain drive systems.

Where an 11-tooth, 1/2" pitch sprocket tends to show up: compact drives on conveyors, elevators, mixers, packaging lines, automatic gates, and similar mechanisms where you need to step speed down or torque up. It also works as an output sprocket on motors and gearmotors, or as a driver on intermediate shafts. With so few teeth, it is worth confirming the chain articulation angle is acceptable for the way the drive will run.

Selection and mounting come down to four things: chain pitch, tooth count, shaft diameter, and how the sprocket will be fastened. Check that the hub bore and keyway match your shaft, and that alignment with the mating sprocket is true, since misalignment causes uneven wear. Chain tension and lubrication have a direct effect on how long the drive lasts. On high-speed applications, look at balance and how securely the sprocket is fixed to the shaft.
