"You might want to just replace the deformed plastic bearings with steel bearings."
That's what I'm thinking of doing.
I'm looking at open builds as a source,
any sources you know of off hand?

Scott, all materials do that. Though in steel, it takes much heavier loads. If you need non-metallic bearings you might want to try ceramic bearings. They'll be a little more resistant to plastic deformation than most common plastics. You might want to just replace the deformed plastic bearings with steel bearings.
Bill in OKC <---- not an expert at anything, not an engineer, and definitely not an expert in machine design. I have been several kinds of mechanic. Parts that deform are either overloaded, or overheated, or both, usually.
HTH!

Hi, My name is Scott.
I joined this group to ask a couple questions regarding bearings as I ran into an odd scenario over this past month.
Bearings deforming while sitting around doing nothing.
I have a laser burner with Solid V Wheels.
I upgraded the z-axis to one with a manual adjusting knob making it easier to put the laser at the right spot.
I let the thing set there for about a month and when I turned it on the other night, that axis was frozen in place. I had to manually force the axis to move, but when the wheels rotate 360 degrees, the bearings lock in place.
So I swapped out the bearings for ones that didn't have this problem and the next morning the bearings had developed the same but not as severe condition.
Has anyone heard of this happening before?
Are there bearings out there with plastic or nylon ball bearings that will deform should they be holding up a bit more weight than what they were designed for?
