Product review (1 stars): Very bad roller shaft design
This product is just a bad design, like others have said the shaft that holds the roller is very fragile and I have replaced this part twice, once on each side, and like another reviewer I finally just crazy glued the rollers to the shaft, we'll see how it goes, next will be to fill the center of the roller with epoxy, or I'll build a new shaft with a large short stainless steel bolt washer and locking nut configuration to re-engineer the plastic faulty shaft design... you can go ahead and buy this part, but it will fail again and again. This part needs to be redesigned, recalled, and replaced by the manufacture.
