Linear Bearing Deformation?
I have not completed my printer assembly yet but I am slightly concerned that I might have torqued the lock nuts too much on the Y bearings causing bearing deformation. It moves back and forth decently but seems like more friction than one would want. I have loosened and retorqued to the specs in the directions but I am still concerned. The double bearing side is my concern, not the single bearing on the right side. The single bearing moves very smoothly, more so than the double side. Is there a way to determine if I need new bearings or do I have to wait until I start running some prints? Please help! Thanks.
RE: Linear Bearing Deformation?
These bearings do not slide like silk, really. Two have more friction than one. Tighten them just so that the housing does not move (refer to the online building manual and the comments by other users there) and then carry on, unless you have created deformation to the bearing housing already.
I try to give answers to the best of my ability, but I am not a 3D printing pro by any means, and anything you do you do at your own risk. BTW: I have no food for…
RE: Linear Bearing Deformation?
While possible to permanently deform the housing, it would take significant over-tightening. Bearing tolerances are quite small, so a very mild over-tightening would be enough to cause higher friction than normal. Running in this state will cause high wear on the bearings and rods (ask me how I know). As just 3d said, you want to tighten just to the point where the bearing housing just stops moving in mount. The bearings should actually take some force to move on the rods, but should be smooth when they do move.
