Basic Features

The features highlighted below are found throughout the WCP Molded Pulleys.

Hex Bore

The 24T x 9mm wide plastic pulley features a 1/2" hex bore and an integrated alignment notch to simplify the timing of stacked motion components. This design ensures proper orientation during assembly, reduces the chance of misalignment, and allows multiple pulleys to be synchronized on the same shaft with ease.

The 5/16" pulley slice does not include an alignment notch, as it is designed to be used in combination with the 9mm wide pulleys.

Alignment Pocket

The pulley slices feature alignment nubs, highlighted in green, and matching pockets, highlighted in blue, that interlock to ensure accurate alignment during assembly.

Bolt Circle

The Molded Pulleys feature a 0.875" bolt circle designed for use with the included #2-28 thread-forming screws. These screws cut directly into the plastic to create durable threads, ensuring a secure connection and long-lasting performance.
