Product review (5 stars): Great replacement part for a poorly designed dryer.
This appears to be a direct replacement part for my Samsung dryer. It fit exactly like the original part and functioned well. I would not hesitate to order another one of these parts if it were to fail again.

Note: The design of a lot of dryers to use a bushing for a pulley that runs at high speeds is poor engineering. A roller bearing or ball bearing design would be far superior to a bushing with what appeared to be no lubrication from the factory. When I replaced this part in my dryer, I liberally applied some general automotive grease to the shaft and bushing on this idler and all the drum rollers (also bushings) to hopefully delay another failure.
This is a complaint of the original design of my Samsung dryer and not of the sellers part.
