Encoder coupling

SC70

A coupling is a device that connects two shafts for purpose of transmission motion. Coupling compensates for geometrical misalignments and axial motion of connected shafts enables the encoder to work within specified accuracy and prevents excessive bearing load. Permissible shaft misalignments must be kept within limits.
