TPC Mechatronics RSFU Series Heavy-Load Ball Screw Nut (U-Type, Single Flanged)

The RSFU Series is a precision ball screw nut line from TPC Mechatronics: U-type single flanged nut for large-diameter, heavy-load ball screws from 50 to 100 mm.

Key features

Ball screws convert rotary motion into linear motion with high efficiency, reversibility and high positioning precision
Large balls and multiple circuits give very high dynamic and static load ratings
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
