ilfcr'a® f&Msd ELASTIC COUPLINGSSTANDARD AND SPECIAL APPLICATION COUPLINGS STANDARD ELASTIC COUPLINGS Eltra elastic couplings are essential parts for motion transmission to the encoder shaft. Couplings are aluminium alloy made and are composed by a cylindrical body on which there is a helical groove that determines: • torsional rigidity • ability to compensate for slight shaft misalignments • ability to absorb shaft axial play Elastic coupling can be supplied with different coupling diameters Ordering code example: G 25 A 8 / 10 means d1 = 8 mm, d2 = 10 mm STANDARD ELASTIC COUPLINGS ORDERING CODE G 25 A 6 / 8 SERIES precision elastic coupling G MODEL (see table) 20 (see table) 25 (see table) 30 SHAFT FIXING TYPE shaft fixing with grub screw A HOLE DIAMETER d1 0 6 mm 6 (mod. G25 / G30) 0 8 mm 8 0 9,52 (3/8”) mm 9 0 10 mm 10 (DO NOT ADD IF d2 = d1) HOLE DIAMETER d2 0 6 mm 6 (mod. G25 / G30) 0 8 mm 8 0 9,52 (3/8”) mm 9 0 10 mm 10 STANDARD COUPLINGS For proper installation it is recommended to insert shafts in the coupling observing “E” dimensions.

SPECIAL APPLICATION ELASTIC COUPLINGS Special application couplings are designed to meet extreme coupling conditions such as high torque or severe axial or radial play. Please refer to single product description to identify right elastic coupling for your application. GS-DA SERIES GS-DA series are double loop plastic coupling with medium torsional stiffness, low restoring forces with impact and vibration damping effect. It allows a smooth running, maintenance-free motion and a reliable compensation of radial, lateral and angular misalignments. It is also thermally and electrically...
