General catalog for download
A benefit of a rolled ball screw with flanged nut is the increased rigidity and precision of the system due to better bearing of the balls. In addition, axial displacements are reduced, which leads to improved accuracy and repeatability. It also enables easy assembly and disassembly of the system. For higher accuracy and service life requirements, we recommend ground ball screws,optionally with ETA+ technology for enhanced energy efficiency.
Technical data and dimensions
The load ratings listed here apply to accuracy class T5. Use factor 0.9 for T7 and factor 0.7 for T10 in order to reduce load ratings.
Further specifications, dimensions and information on service life calculation and lubrication can be found in the general catalog for rolled ball screws.
