High quality encoder couplings 

To connect two shafts together for the transmission of motion encoder couplings are used. The coupling compensates geometrical misalignments and axial motion of connected shafts, enables the encoder work within specified accuracy and prevents excessive bearing load. We offer a range of high quality couplings for different uses.
