The coupling compensate geometrical misalignments and axial motion of thèse shafts, enable the encoder work within specified accuracy, prevents excessive bearing load and opération without crashes. The permissible misalignments of shafts must be kept by user according to requirements for each model of coupling as shown in the table bellow. There is no need to use an external coupling if the encoder (hollow shaft) has the incorporated one. http://www.precizika.lt E-mail:info@precizika.lt ISO 9001:2000 MECHANICAL DATA Coupling model SC30 SC70 SC98-1 SC98-2 ♦ Kinematic accuracy (with parallel offset < 0.05 mm and angular misalignment < 0.09°) +10 arc sec. +2 arc sec. +0.5 arc sec. +1 arc sec. ♦ Torsional rigidity 150 Nm/rad 4000 Nm/rad 6000 Nm/rad 4000 Nm/rad ♦ Permissible torque 0.1 Nm 0.5 Nm 1 Nm 1 Nm ♦ Moment of inertia (approx.) 3x10" kgm2 2xl0"4 kgm2 2xl0"4 kgm2 1.7xl0"4kgm2 ♦ Permissible radial misalignment ^0.2 mm < 0.3 mm < 0.3 mm < 0.3 mm ♦ Permissible angular error <1° <0.5° <1° <2° ♦ Permissible axial motion < 0.2 mm < 0.2 mm < 0.2 mm < 0.2 mm ♦ Permissible shaft speed 16000 rpm 3000 rpm 1000 rpm 1000 rpm ♦Weight 27 g 0.22 kg 0.25 kg 0.21 kg ♦ Compatible with encoder A28 A36 A58, A58B A58C, A58K A110 A170 A170 SC30 L D, » - J 04H7, 05H7 06H7, 08H7, 01OH7 01/4", 05/16", 03/8" L 22 30
