Ball bearing

Well… Its a ball bearing. Not much to say except that I like them (but I don't like replacing them) and now with Cycles I thought that I try to make one as photo real I could. I know there are some mistakes in both modeling and texturing and I also know some of you will think I have gone overboard with the chromatic aberration and you are probably right but I like the effect in this case.

Rendered with Cycles, 1000 passes in 51 minutes.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. Gripyournuts on

    I've worked as a machinist and have replace the bearings in a motorcycle. you have done an excellent job with this!

  2. I am a machinist. Ball bearings are always that clean fresh from the package.  The only texturing improvement I can see to make is that the flat faces of the outer and inner raceways of real ball bearings have an anisotropic texture which is generated by precision face grinding of those faces.  The grinding process creates a texture that looks like the overlap of multiple layers of scratches at different angles that lie on chords of the circular faces. Look closely at the faces of a real SKF ball bearing and you'll see what I mean.

  3. Very good. Do bearings have oil though? I was always under the impression that they were constructed in a way similar to brushings, where they did not need any external lubricant.

  4. Very nice job.  I'm not familiar enough with them to comment on the modelling accuracy, but they look great.  The only crit that I can think of is the oil on the bearing in the back.  It is a little to clean looking (maybe its because the only oil I deal with is when I change the oil in my car and I always wait too long, so the oil is very dirty and brown and full of debris.
