⚙️ UCF201 8 Self Alignment Pillow Bearing: Superior Pieces for Precision Performance Review

Media could not be loaded. Bought 4 of these for a project I'm working on. Didn't expect high quality for the price but how they even passed quality control is beyond me. Only one of all four is even remotely correct. The bearings do not seat properly in the block, rendering them useless.

The one star reviews are fake because the people who wrote them don't understand how they work. Yes they can go wrong because they are designed to move in a self-adjusting housing. As clearly stated in the product description, they can be straightened with a pole and some leverage. It's great quality and a great price.

This is exactly what I expected. 2 floats smoothly in the pockets. The other two needed some penetrating lube and were easily loosened with a rubber mallet to loosen them up. Just in case, I ordered twice what I needed but paid less than I paid for 1 precision cast support block. If you want something super accurate, pay for it. If your project has some room for slops, they will work just fine.
