Products Features
Shaft Couplings are divided into the following most common categories according to type:
Metal diaphragm coupling: suitable for servo motors, encoders, planetary reducers, ball screws, compressors, mixers, paper machinery, robots and other mechanical equipment. Plum-shaped coupling: suitable for encoders, servo systems, motor spindle drives, packaging machinery, machine tool drives, pumps and other machinery. Bellows coupling: suitable for encoders, CNC machine tools, positioning systems, ball screws, indexing discs, planetary gear reducers. Spring coupling: suitable for rotary encoders, stepper motors, screw rods, etc. Parallel coupling: suitable for connection of stepper motors, encoders, screw rods, etc. Cross slide coupling: suitable for tachometer, encoder, screw, machine tool and other machinery. Universal coupling, rigid coupling.
>Integrated structure, the overall use of high-strength aluminum alloy materials
>Elastic action compensates radial, angular and axial deviation
>Spring design, with buffer effect
>Special design for encoder, micro motor
>Fastening method of set screw
