Ball screw fixed end DIY support ideas needed.

[Swarfing]

Marco you could always go with a bronze bush (oilite bearing) and a couple of thrust bearings at each end as a cheap option?

It could be an idea, but i still have to find a way to build a main assy that carry all parts.

Do you have a photo of a similar implementation ?

i had the same prob as you , i had a 12mm diameter trapezioid screw , so i turned the screw down to 8mm using a grinder and a drill as a lathe , threaded the end for a locknut , used a 100mm x 100mm x 10mm plastic shim with a 22mm hole drilled in it( to take a skate bearing) as a bearing block. so it went , thrust washer - bearing block (with skate bearing ) - thrust washer - locknut , tighten locknut to preload assembly , solid and cheap i have no lateral movement in screw ..... phew!!! maybe a pic would have been better

Hi John,
yes, a pic would be good.

It's all clear thrust washers aside.

Unfortunately the screwballs machining requires a good lathe and proper skills, any other attempt will fail unsafely.

Here in Italy, lathes are quite expensive, anyway i'm thinking to buy a little one at least to work small parts.

Could you take a shot of your assembly ?

Thanks,
Marco.
