The Carrier P461-3202 4-inch Adjustable Motor Pulley is a mechanical drive component designed for use with a 1/2-inch motor shaft in systems and other belt-driven equipment. Its adjustable pitch design allows to modify pulley diameter settings, support to regulate fan or blower speed to meet specific air flow requirements in HVAC systems. This pulley is installed in air handlers, ventilation units and commercial heating and cooling equipment where precise speed adjustment is needed. Within the system, it transfers rotational power from the motor to the driven component, supporting efficient operation, system balancing and performance tuning during connection.
