Every rotating wheel in your life has a bearing of some sort in it. Your car, the mower, the UPS truck, the shopping cart at walmart. They are everywhere. If you have any full-extention drawers in your house (especially on filing cabinets), they have bearings. Any heavy entrance doors, have bearings in the hinges. If your garage has power tools, air compressors or scissor jacks, they all have bearings. A box fan (or any air moving fan-there's a ton of them) has a bearing in it. If your search extended into your place of work, the number of applications is endless. Just look for any thing that is spinning or has a heavy object with rotational movement.
