Hi

I am currently building a cnc

I have on hand my lead screws "Nook Acme screws 1/2-5 10tpi " .

I need help to find the proper end bearing support and anti-backlash nut housing designed for these type of screws.

Can someone help me finding the right model and the right place to buy it.

Thanks

Jack

Here you go...

Nook Industries Engineering Tools

Inch Critical Speed or
Metric Critical Speed

Once you run the calculators, you can see optimum types of bearing support. I have single bearing support on my 1/2-5 10 Acme Rods with very little backlash. My rapids are not fast, but not slow either. I don't recollect the rpms off the top of my head. Built my own supports out of HDPE and roller bearings.

Thank you for your answer,

I don't think they have local distributors close to me in Quebec and I don't think they have an online shopping service.

Is there an other way to manage without having to buy specific Nook bearing parts ?

They have a 'Customer Connect" link and an online chat service. If you haven't tried yet, it might be worth a quick phone call or chat to check for sure.
