Hi guys, is possible to calculate if can use just one linear Bearings or need to use two?
I have 2 models SBR16UU and SBR16LUU
SBR16UU is 45mm length and SBR16LUU is 90mm
i show 3 drawings, top base are MDF 220x170x18mm size
need to choice between these configurations
Option 1 - Use Two Small Bearings
Option 2 - Use just one Small Bearing (45mm)
Option 3 - Use one long Bearing (90mm)
Thanks
