I purchased 2 8020 bearings. They are very smooth when I do not attach anything to them. The attached picture shows the bearings and what I am trying to do. I attached a piece of wood where my Z-axis will mount to and then it hardly slides at all.
How does everyone get these things to slide easy when they are attaching their parts to them?
Hope I explained this well enough. I really want to use them and try something different. I have trollies with bearings but really want to get these to work and try them out for a while.
Many thanks for the help in advance and happy holidays.
