Hi All,
I have been learning FreeCAD for a few weeks now. I got stuck on the design of a ball bearing, not just a single ball, the whole race bearing. I only did it as a way of learning some of the features in FreeCAD, and where to find them in the workbenches. I then had a go at designing a roller bearing, similar sort of process, different end product. Neither of these bearings are for any purpose other than learning. I could have gone a lot further with tweaking both of the designs, adding fillets etc. But that bit is easy and doesn't teach me much.
It all started when I was watching FreeCAD tutorials on Youtube and a man drew a roller bearing in Solidworks. I had to have a go!
I have only included the file for the roller bearing, the file for the ball bearing is 1.24 Mb in size, this one is only 451 Kb. I wonder why the difference?
I have also included images of both bearings. Yes I know the roller bearing probably shouldn't have slots in it!

Looks cool. How long did it take you?
