Rheem-Ruud PD710004 Sheave 4.75"DIA 1-1/8"Bore 2.156"Hub Variable Pitch

The Rheem-Ruud PD710004 is a Variable pitch sheave that is utilized in heating ventilation and air conditioning and systems that are a part of building infrastructure. This component has a diameter of 4.75" a bore of 1-1/8" and a hub length of 2.156", which is of great significance while changing the speed of the motor and the air flow. This is made possible with the assistance of the sheave which together with the V-belt assist in determining the speed of the motor. As the position of the sheave changes the length of the path of the V-belt changes and therefore the speed of the motor and hence the air flow rate developed by the blower.
