These are very basic standard bearings. They will only work at the dimensions described in the listing, so make sure they fit your project. So far they seem to work fine 👍

I wouldn't get these again. if there is a slight force on them other than a force perfectly perpendicular to the rod they slide on, they bind very easily. if will only slide well if tolerances are very exact. This happened with all 6, so I am guessing it's in the design. They were cost effective, though. I am sure they will work well in certain applications.

you might get two or three alright bearings from the full pack. better to just buy a few slightly better bearings for the same price

Heavy duty linear bearings for 20mm shaft. Smooth rolling, very precise. Recommended
