Product review (3 stars): Need real ball bearing pulley.
Don't last very long,as soon as it gets a little warm plastic pulley slides off brass bushing and then allows belt to burn up. If you could find a garden equipment pulley with real ball bearings you would never have to replace this idler pulley again. I'm going to try and epoxy the brass bushing back into plastic pulley and then grease bushing and see how long it will last and of course order a new one just in case that doesn't work.
