16mm ballnut?

[phantomcow2]

I have some ground ballscrews, 16mm diameter and i assume a 5mm pitch as they tend to go together. My question is, where can I get a ballnut for this?

Isel sells 16 mm nuts, both 4 and 5 mm pitch. Check your nearest dealer.

16 mm is a very common size Isel makes a rolled thread screw not a ground thread and the profiles might not be compatable. NSK, THK, Danahermotion, INA all have ground thread 16 mm screws. Measure thread to thread and make sure that its a single start screw ie put trace a thread through a single revolution and if it is a multistart there will be more than 1 thread travelled. If you are replacing just the nut you probably want an adjustable preload so that you can to the original fit. Many manufacturers match ball size to thread size and you will never be able to duplicate original performance without an adjustable fit.
