• Drive Pulley - Single Motor

The Bard 5070-025 drive pulley for single-motor configurations is an OEM mechanical component used in Bard belt-drive air handling assemblies to transmit motor torque to the driven sheave and keep blower airflow where it should be. If your unit has belt squeal, glazing, improper blower speed, or uneven airflow after a motor or belt replacement, a worn or misaligned pulley is a common root cause. Replacing with the correct Bard 5070-025 pulley helps maintain proper belt tracking and designed blower RPM, which protects the motor and supports stable cooling and heating performance. Verify pulley size, bore, and set-screw location against your Bard parts list for the specific model and serial number before ordering.
