P Model
In belt-driven power transmission systems, a variable-pitch pulley is mounted on the drive shaft. By adjusting the distance between the drive and driven shafts, the belt pitch is forcibly altered to change the rotational speed. This is a continuously variable transmission (CVT) using a single variable-pitch pulley. It is a basic model that uses standard V-belts.

- The travel distance refers to the distance the motor must move to shift gears.
- If the system will be subjected to repetitive loads (such as from a brake motor), please specify the key-type model.

- We can provide holes with the diameters indicated by the symbols in the table above. The ●, ◎, and ○ symbols indicate adapter-type fittings, while the ▲ symbol indicates straight-type fittings.
- Adapters marked with a ◎ do not have a keyway. If using them with a keyed shaft, please remove the key before use.
- Due to the adapter's specifications, the parallel key does not fit; therefore, an L-shaped key is included. Please use this L-shaped key when installing the adapter.
- Please let us know whether the hole diameter for the L-key is for the new JIS or the old JIS standard.
