Review on 🔒 Antrader Precision Miniature Bearings with Shielding by Terrance Singletary

These are good bearings for the price. They adjust to size and rotate smoothly. The surface quality of the outer surfaces is very good. Time will tell if they hold up, but I use them on a belt sander so they won't be too hard on them anyway. Please note that the product name indicates an inner diameter of 0.5 inch. The product description correctly states 12mm, but 12mm is NOT the same as half an inch. The inner diameter is about 0.7mm less than half an inch, so a 0.5 inch shank will not fit. However, I still gave the listing 5 stars because they are good bearings and 6201 is the standard bearing size anyway.
