Product review (5 stars): Perfect Fit
Perfect fit for my Maytag SDG4606AWW dryer.  Since the front of the dryer and the drum had to be removed to replace this roller, I also replaced the drum belt and the Drum Rollers while I was at it.  The drum was rotating very slowly.  The bearings on the old part had failed and this part fixed the problem.  This was a genuine Whirlpool part and the seller was Amazon.
