Bard 5501-003 is an OEM variable pitch pulley used on belt driven fan and blower assemblies in Bard wall mounted HVAC equipment, allowing a technician to fine tune fan speed to restore correct airflow, static pressure, and overall unit performance. This adjustable sheave is specified as 4 inch diameter with a 1/2 inch bore, making it a common fit for motor shafts used in Bard belt drive applications. When replacing a worn, slipping, or misaligned pulley, using the correct Bard part helps maintain proper belt tracking and helps protect motor and bearing life by keeping drive components aligned to factory specifications.
