TPC Mechatronics RSFA Series Ball Screw Nut (A-Type, Single Flanged)

The RSFA Series is a precision ball screw nut line from TPC Mechatronics: A-type end-cap circulation single flanged nut, shaft diameters 6-50 mm with leads up to 50 mm.

Key features

Ball screws convert rotary motion into linear motion with high efficiency, reversibility and high positioning precision
End-cap ball circulation allows compact nuts and smooth high-speed travel
Shafts are available ground or rolled in accuracy grades C0 to C10 with selectable axial clearance/preload (P0-P4) and surface treatments
The table lists ball diameter, root diameter, basic dynamic and static load ratings, rigidity and main nut dimensions for each model
