Arya engineers presents flexible couplings. Due to good mechanical assembling is in operation, the encoder performance- integrity is assured. The shaft encoder is a high-speed pulse generator, and high precision device, which needs accurate rotary motion. To over come the coupling problems, flexible couplings can be used with features, such as torsion rigidity, accurate bore concentricity, accommodate parallel and angular misalignment, unaffected by dust and corrosive atmosphere, etc. These provide synthesis, precise itary motion and in the mean time longer life and greater accuracy. Special non-metallic couplings are available in order to protect the encoder from mechanical stress, thermal shocks and electrical leakage current.
