TPC Mechatronics RSFBH Series Heavy-Load Ball Screw Nut (Multi-Circuit, Flanged)

The RSFBH Series is a precision ball screw nut line from TPC Mechatronics: Heavy-load flanged nut with 2-4 circuit rows and lubrication ports, for shaft diameters 50-120 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
