Rolled Ball Screws Flange nuts on mounting sleeve 8446 - Flange single nut with multiliner, wiper on both sides, two or more threadstarts • Price-performance optimized • Standard according to ISO3408 specification or with mounting thread • Customized A benefit of a rolled ball screw with connecting thread nut is the higher rigidity and accuracy. In addition, the connecting thread nut enables an 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. 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. Customized options: - Customized development, other sizes - Assembled ball screws according to drawing, including end machining with assembled nut - Accuracy: ground ball screw design for higher precision requirements - ETA+ technology for increased energy efficiency - Customization of geometry, journal, material design - Preload / backlash: axial backlash, radial backlash, preload, backlash-free - Adaptation to environmental conditions e.g. clean room, non-magnetic, low temperature, vacuum - Lubrication: Special lubrication, lubricant-free, special wiper - Further assembly to spindle with motor Specifications: - Nominal diameter: 50 mm - Pitch P: 20 mm - Ball circles: 3+3 i - Length: 90 mm - Diameter D1: 28 – 105 mm - Dynamic load capacity: 10,1 – 123,8 kN - Static load capacity: 12 – 328,6 kN
