Very smooth.
I used these with 3/4” steel rods to add sliding extension support to miter saw station. Extension slides effortlessly, even under load.

The bearings are not very smooth...
The price was good, but the bearings are not very smooth. Even on a highly polished, stainless steel rod, you can definitely vibration caused as the individual bearings roll through their respective tracks. Luckily, my use-case only relies on these bearings for initial setup and adjustment. When the automation is running, the bearings won't be moving, so these work well-enough for this type of implementation.

Do Not Turn Smoothly
I returned this product because they did not turn a perfectly milled piece of brass smoothly, which was essential for my project.

Tolerance
This bearing was too loose for my application and so I used the 55mm one from uxcell and it worked perfect. Doc'
