Rolled Ball Screws, Compact Nut, Shaft Dia. 25, Lead 5
Rolled ball screws with a compact nut for a lower-profile linear-motion layout and a longer stroke. Choose BSSC or BSSCK, then shaft length L and, for BSSCK, F and P.
- BSSC is the standard type; its nut travel range Y is L−118.
- BSSCK allows F and P to be specified; its nut travel range Y is L−(91+F).
- For BSSCK, F is selectable from 27~45 and P from 10~15, with F≤P×3.
- The nut travel range Y must be greater than the overall nut length.
