Bard 5070-024BX is an OEM drive belt used in specific Bard wall mounted HVAC equipment, including applications that reference 5070-035 and 5070-036 assemblies. This belt transfers power between the motor and the driven blower or wheel so the unit can maintain proper airflow and stable performance. When a belt is worn, stretched, or cracked it can cause reduced airflow, noise, or slipping, so replacing it with the correct Bard part helps restore proper operation and reduces premature wear on pulleys and bearings. Confirm fit by matching your unit model and serial number and comparing the belt size and style to the parts list before ordering.
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
