Frequently asked questions

Both use the same 12 mm diameter, 4 mm pitch and SFU1204 nut. The only difference listed is the length, 200 mm here and 650 mm in the other version.

What does the 1204 in the name mean?

In ball screw naming, 1204 indicates a 12 mm nominal diameter and a 4 mm lead (pitch), meaning one nut travel of 4 mm per full screw revolution.
