A compressor for a heating, ventilating, air conditioning, and refrigeration (HVAC&R) unit includes an impeller, a shaft configured to rotate the impeller, and a fastener. The impeller includes an opening and does not include keys, splines, pins, or any combination thereof. The fastener is coupled to an end of the shaft and extends through the opening of the impeller, and the fastener is configured to stretch in an axial direction relative to the shaft via a tensioner during assembly of the compressor.
