uxcell LM8UU Linear Ball Bearings 8mm Bore 15mm OD 24mm Length for CNC Machine 3D Printer 4pcs

I purchased these for a flight simulator throttle upgrade, and they have been perfect. I wiped them down a little bit before use because they were quite oily; but, after that they have been perfect!

The material is high quality. I’m happy with the color and compact factor. If I need to buy more for a future upgrade, I’ll buy more of these. I gave 4 out of 5 stars because one of the four bearings is a little tight on the rod. I expect it’s still within tolerance, though. The other three bearings glide very smoothly on my rods and I’m very happy with them. I only needed two, so the third will be a swap-in replacement when needed, and the fourth will be for last resort while a new order is on its way.

I bought these to replace a bad bearing on my Prusa Mk3. The old bearing was missing a couple balls and made a bad noise. These were worse than the original broken one. There was a lot of slop on the rod and they were very rough. I put the broken one back on until I can find a better replacement

Not bad compared to a different brand I recently bought. These slid easily on the 12mm rails I bought. One of them was gritty and probably won't use it

The linear ball bearings arrived as scheduled and were used as a replacement on an exercise equipment. So far I am very pleased with the item and would definitely purchase again from this seller.

Used to replace bearings in a harbor freight miter saw. Worked perfectly. Needed to add lubrication. Good for the price!

Been looking for some linear bearings to fit a need, and the specs on these met that need. Received them in a timely manner. Well packaged. Happy camper!

My first impression was that the surface finish was very nicely machined. That kind of told me tha the rest was nothing to worry about. The shipping and delivery, once again was timely and professional which always makes me happy!
