Spring Flexible Rotary Encoder Coupling 10mm To 6mm 8MM Screw Thread Winding
GM screw thread setscrew series coupling winding coupling
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.
GM screw thread setscrew series coupling winding coupling has the following advantages:
>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
