Mechanism with vertical shaft
[FONT=Arial]Hi,[/FONT][FONT=Arial]
[/FONT]
[FONT=Arial]First off, I am an artist, not an engineer! I'm building a spinning artwork...[/FONT]
[FONT=Arial]
[/FONT]
[FONT=Arial]I have built a mechanism that has a vertical shaft with a bracket at the top. An artwork bolts to this bracket with a load of approx 5 kg. The artwork then spins at approx 120rpm.[/FONT]

[FONT=Arial]The pictured design (photo) works fine, except there is some play in the shaft / bearings that I would like to eradicate. Since building this version I have done a lot of reading and updated the design as shown in the diagram.[/FONT]

[FONT=Arial]Currently I have a clearance fit on the shaft/bearings. I understand that I can heat fit the bearings and this will result in zero play. However, I am confused about how the load is distributed. So here is my question...[/FONT]
[FONT=Arial]

[FONT=Arial]If the radial bearings are heat fitted to the shaft, doesn't this remove the load from the thrust bearing? My understanding is that I want the weight on the thrust bearing and to use the radial bearings for guidance.[/FONT]

[FONT=Arial]Any advice will be gratefully received ! [/FONT]
