Hi Guys,
I would recommend contacting Action Bearings.
(
http://www.actionbearings.com.au/)
A mate of mine just converted his mill to rolled ball screws with 2 nuts on each axis and I'm positive that the total cost was below $500.
This was for 3 pieces of thread and 6 ball nuts.
It was the Kensington branch that was contacted and the sales rep was Brett.
If you purchase from them maybe you could mention that Jayson from Horsham recommended them.
I don't get anything out of this however I have pestered them quite a bit and they haven’t got any of my money... yet. A few purchasers might make up for it a bit.
I will definitely be purchasing from here once my finances allow.
Regards,
Jayson
