Ball Screws and Ball Screw Nuts Properties • We provide various rolled ball screw sets: ranging from Ø 6 to Ø 80 mm, in quality C7, with various pitches, as right-hand and some left-hand threads, in lengths up to 3000 mm • Standard products are Ø 12 to Ø 40 mm, right-hand thread, nuts with double-sided flange cut and preload of P0 • Material: steel 50CrMo5QT, surface hardened 58-62HRC, hardening depth 2 mm from thread root • In the following overview, the preferred types which are mostly available from stock are marked in red • Higher preloads, ground screws, round nut flanges, etc. are available on request • A higher preload of the nut enables a more precise positioning but leads to less efficiency • Ball screw sets with preload P1 to P4 are delivered only in their assembled state. For preload P0, we deliver the screw and nut separately. • End machining for fixed and floating bearings made according to your drawings are available on request. For examples, refer to pages V 061 and V 062 • Note that screws can buckle when installed vertically and placed under pressure or lifting loads • Take the screw torsion into account when operating at high turning speeds
