Bard part number 5501-020 is an OEM double pulley round drive belt assembly used in select Bard wall-mount HVAC units to transfer motor rotation to a belt driven component for steady airflow and dependable operation. When a belt is worn, stretched, glazed, or cracked, you may notice slipping, squealing, reduced fan speed, or inconsistent cooling performance, and replacing it with the correct Bard belt helps restore proper drive geometry and reduce premature wear on pulleys and bearings. Because belt length and profile must match the original design, confirm your unit model and serial number against the Bard service literature before ordering to ensure correct fit.
* Orders less than $50 may incure a minimum order fee.
