Product review (2 stars): They seized to the shaft
I have to admit they worked up until this week.  I remember now, when I installed them, of being slightly concerned because these rollers were definitely NOT whirlpool/kenmore FSP (factory service parts).  The rubber portion seems to be intact and functioning as it should.

But it is obvious the bushing is sub-standard, and oil impregnated or graphalloy or what ever it should be, it is NOT.

I managed to pull them off last night and re-grease them and finish the laundry.  but I know the grease won't last long...
