Wherever possible, a type A flange is recommended, above all if the assembly involves a rotating nut, so that the nut is balanced. SHUTON·IPIRANGA recommends a centred flange when radial forces cannot be entirely eliminated from the nut. Sometimes there is no other option but to use a cylindrical nut and fasten to the table with a keyway. The standard dimensions for this keyway are a function of the nominal diameter of the ball screw and the dynamic load according to the following tables: d 0 Y M 20-25 6 2 32-40 8 3 50-63 10 4 80-100 12 4 120-160 14 6 C a N < 25000 15 < 50000 20 < 100000 30 < 150000 40 < 250000 50 ≥ 250000 60 = = N M d0 Y 27
