Product review (5 stars): Repair pulley for Whirlpool dryer
It is exactly what was needed.  I got exactly what I bought.  Unfortunately for me it came 4 days after I got the dryer back together so I could clean our clothes.  Couldn't wait for it.  Next time I open the dryer up, I will replace this.  I took the old one out, lubricated it and returned it to the dryer.  Worn but worked.
