Schaeffler describes this part as a radial insert ball bearing. It is cataloged as a generator drive end bearing, generator commutator end bearing and alternator bearing, and is listed for front, rear and drive-end positions depending on the application.
Signs an alternator bearing may need replacing include a whining, growling or grinding noise from the alternator that changes with engine speed, or roughness or play when the pulley is turned by hand. Diagnose the source before replacing parts, because a worn belt, tensioner or idler pulley can make similar noises. Each listed application uses a quantity of one, and this listing is for one bearing.
