TPC Mechatronics RSFB / RDFB Series Ball Screw Nut (B-Type, Single and Double)

The RSFB / RDFB Series is a precision ball screw nut line from TPC Mechatronics: B-type flanged nut offered as single nut (RSFB) and double nut (RDFB), shaft diameters 32-50 mm.

Key features

Ball screws convert rotary motion into linear motion with high efficiency, reversibility and high positioning precision
Internal ball circulation keeps the nut outer diameter small
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
