Joomen CNC SBR16-2100mm LINEAR SLIDE GUIDE 2 RAIL+ 4 SBR16UU BEARING BLOCK

Using these in a CNC project. They are very nice for the price and run smooth. I have the rails indicated parallel to each other .004" over the length and there is no binding or tight spots. Slides run smooth. Very rigid.

Making a table for flatting wood slabs, I think its going to work out just fine.

Worked perfectly for building a XY table for a router lathe.

The slides aren't very smooth and the bearings fell out after a few cycles.

Only one of the 4 bearings slides freely and the 3 that do not move freely create loads of metal shavings
