MIG MAG Welding Machine Ball Bearing mounted Wire Roller

thingiverse

Hi all, today I present you a ball bearing mounted wire roller, actually build for my MIG welding machine. I tuned my welding machine and figured out that the standard holder for the wire roll is just fix with leads to a high friction between the roll itself and the holder. So, I created a ball bearing mounted thing and to be honest it works awesome. On the pix above you can see the old simple one and the new one in gray/red. You will use the original bore holes at the welding machine. Furthermore, just put the wire roll on and fix it with the clamp. Easy and simple. I used two standard ball bearings Type 6804 = 61804 - 20 x 32 x 7 mm. The tie rod is a M10x90 on the photos. But actually it is too long, so a M10x80 would be better.
