Elastic couplings

G 20 / 25 / 30 A

Eltra elastic couplings are essential parts for motion transmission to the encoder shaft.
Couplings 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
