Description

Edit 29/nov-2023:

In order to make the bearings slightly less tight, you can fidget/roll with them for some time. Also I've applied a smidge of lithium grease in order to make the bearing roll MUCH smoother.

Edit 22/oct-2023:

If you have trouble with the rollers “growing” into the inner and outer rings, you need to lower the gap closing radius in the slicer. In OrcaSlicer, this is found under Quality > Precision

Print in place 608 Roller Bearing for mechanical prints.

My bearings are greased in-between the rollers with lithium grease, ensuring smooth motion and longer lifetime for the bearing.

The model has pretty tight tolerances, so each individual roller has to be broken free. Do this carefully as to not snap the rollers. However when the rollers are broken free the bearing is very smooth and tight, with very little axial movement.

This model is reverse engineered and redrawn from scratch from @MatveyKukuy's Ultimate 608 bearing. This remix features another roller and user definable tolerances(in the f3d-file).
I had no benefit from using different radial- and tenon tolerances (RT and TT), so for this model, only a single tolerance is used.
Also added a chamfer on the edge, to match machined bearings.

The bearings in the images are printed with 'Dutch Filament (MCPP) Glitter Grey PLA' at 0.23mm layer height with a 0.4mm nozzle on a Bambu Lab X1C.

Do you enjoy my work?

Feedback, makes and ratings are much appreciated. I'd love to see what you have printed and hear about your exciting builds.

kinda too tight but they work

@Cernott

Hi! Thanks for downloading! These bearings get slightly looser over time, so if you fidget/roll with them for some time, they should get less tight. Also applying a tiny bit of lubricant makes them roll MUCH smoother.

looks cool but it doesn’t spin

@Cernott

Thanks for the rating! In order to minimize the play in the bearing, the tolerances are REALLY tight, so it can take quite a bit of work to get the rollers loose, depending on filament and printer calibration.

@DavideMarcolini

I think you did a good job designing this model, this thing is the precision is so high that you really risk having a bearing that doesn’t work, like in my case. Eventhough I like pushing the limits of 3D printing in this case it’s best to buy a steel bearing in my opinion. But I want to be clear, you did a really good design.

worked pretty good for a 3d printed bearing

@Cernott

Thanks printing my model, and for the nice rating :D

100% accurate @addikey it printed, but it does not rotate and won't break free. I ended using these in my design though and it was actually working fine for the design in question. If you need a proper functioning bearing, do not use my profile and also, probably avoid this design.

Hi! Thanks for downloading my model! I have looked into this problem, and have updated the description. Please check out the fix there! (:

printed on tack plate. gray pla. first layer glued together. but machine is well calibrated. just printed another ball bearing from other designer but same size and came flawless

Thank you for rating! Strange the bottom is fused.

Printed okay, but like other users have reported, it's really hard to break in initially. Once broken in though, it rolls just as smooth as other bearing models. Just takes a little longer to break in

Perfect design

The designer has replied

@Cernott

Thanks a lot, glad you like it!

@Cloneman

Hello, A little careful work until the rollers come off, but then perfect. I first use the bearing as a figet for a few hours, then the rollers run smoothly.
