New Y bearings
Hi
I use these to reduce the noise from the carrige. Having good results so far 🙂

What do you think ?

so the 8mm fit perfectly?

I have them fitted to my Mk1.
However, they are designed to fit inside a metal case and not with cable ties, so they do introduce some additional lateral movement, but I have not seen a problem with my prints so far.

YES!
@Ben,
I use super glue to fix them to the zip ties and it works very well but to be honest i doubt it was necessary as the original bearings also move a bit inside the zip ties....

There's a discussion on this over on https://www.facebook.com/groups/Prusai3users/ , scroll down and you should spot it...
Re: New Y bearings
Yes I though I might be able to carry on the argument here 😆
Seems they fit x and y but not the z.
Re: New Y bearings
They are drop-in replacements for LM8UU's.
I have these installed on my Y-axis currently, and they seem to be working reasonably well.
My Y bearings, straight from PR, were bad. The rattled pretty badly.
For starters, I never liked the way the bearings are mounted with zipties, so I have them sitting on actual printed blocks. I lose like ~6.5mm height putting the bearings on these blocks, but I can live with that.
There is still some play if you force it by hand, but less play than what I had with the bad LM8UU's.
But that's also because I had the prescience to buy at least 6 of them so I could pick the tightest 3. That seems be the biggest issue when using these bearings, and that's why the reports of the performance of these bearings are so varied.
I think these bearings should be biased in some way in order to take up the slop. You get a little of that with gravity on the Y-axis and the natural interference between the smooth rod misalignment.

For those in the UK or anywhere else. There is a guy selling them cheap on the facebook group 😉
Re: New Y bearings
I just upgraded my printer x axis with these and its remarkable how silent they are 🙂
I have read about the issue with the tolerance and there are aluminium enclosures for those bearings but i will with without them first as the ones with the aluminium cost a lot like 6 Euro each. Also i wold have to rediesign the extruder part and to buy a wooden y-carriage to make the new ones fit. Wich is a lot of work and money. So i will see how these go.
After all the printer is designed to work with normal bearings who can be quite sloppy at times....
Re: New Y bearings
I have some on the way so I will also update when fitted. I cannot wait to hear the difference.
