DIAGRAM FOR JOINTS SERIES .:: S-G ::.     example: Power: 0,65 KW R.P.M.: 230 With working angle 10° Factor F=1 we get point P. Torque=27 Nm corresponding to joint size <D> = 25/26 mm. = Types 04S, 04G, 1GB. With working angle 30° Factor F=0.45 (Kw 0.65 : 0.45 = 1.44 Kw) we get point P1 Torque=60 Nm corresponding to joint size <D> =32 mm. = Types 1S, 1G, 3GB. Consider that:: Torque in Nm = (9550 x KW) / R.P.M Torque in Nm = (7020 x HP) / R.P.M     N°1 KW = 1,35 HP - N° 1 HP = 0,736 KW   N°1 Kgm = 9,81 Nm - N° 1 Nm = 0,102 Kgm
