Product review (5 stars): Real steel pulley, won't break like the cheap gray ones!
High quality steel pulley, unlike the original manufacturer's junk aluminum/zinc pulley that breaks/strips threads. Buy this one and you will not be sorry! Fits my Amana dryer with motor #2200376 (check the ID tag on top of your motor). Pulley is reverse-thread, for a 3/8" reverse-threaded shaft. Don't know about other motors, but this is probably a common standard for many dryer motors.
