Frequently asked question (FAQ)

Question: What is a coupling?
Answer: A coupling is a part that connects two different rotating bodies (motor shaft, ball screw, etc.) and aims at transmitting torque. The load of assembly adjustment is reduced by absorbing the axis deviation (lateral misalignment, angular misalignment and axial amplitude) between rotating bodies. And in case of accidental overload, the coupling is destroyed and the rotating bodies are disconnected to protect the expensive power part and the whole device.
Question: What are the types of MISUMI couplings?
Answer: There are disc type, grooved type, cross type, claw type, bellows type, rigid type and universal joint type.
Question: How to select coupling according to motor?
Answer: Disc type is recommended for servo motors, grooved type is recommended for stepping motors, and cross type is recommended for universal motors.
Question: How to select according to the purpose, environment, working conditions?
Answer: Please refer to specific instructions.
