I know what you mean, and its doesn't seem right, having experience in automotive, bearings just don't hit me as a piece of plastic to take on wear and stress of any kind, bearings are metal, either roller or ball bearing.....even in a Whilpool/Kenmore spin bearings are nothing more than a metal sleeve, no roller or ball bearing, just metal sliding on metal, to me equals stress, tension, and heat, that will wear out quickly, or cause a groove in one of the metals, this is something you would see on a kids toy car, they just slide a wheel onto a metal post, eventually it wears thru and breaks, how long do you think this will work on a real car?.......better yet take a FL machine, and slide the shaft thru a metal sleeve to ride on, how many loads do you think it would take to for this to wear out?.......
but yes, GE FF is another one of those ingenious, yet simple machines that functions well, a time proven design, and the worst part was when they canged to all plastic, what a waste.....
