Review on Susans Square Turntable Bearings Capacity by William Runninger

They are made of thin metal and can easily be bent by hand. In fact, I had to straighten most of them because they were slightly bent out of the box. They should be slightly thicker or made of heavier steel. They're good for light use, but I wouldn't use them for anything over 20 pounds. The bearings rotate quite well and smoothly under light loads. They work great when glued to 16" pizza trays and used for turntables (Lazy Susan) in my closet, but aren't strong enough to be used in my shop.
