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 the MISUMI website.
Question: What kind of coupling should be used when the angular misalignment is very large?
Answer: Please select the universal joint with allowable angular misalignment of 30 degrees. In addition, when grease cannot be applied regularly, use a rubber sleeve to fill grease and use it.
Question: Which disc type coupling is better, single disc type or double disc type?
Answer: Double disc type can absorb angular misalignment and lateral misalignment, but the total length will increase.
Although the total length of the single disc type is short, it is only suitable for applications with narrow space because lateral misalignment is not allowed in the structure. Special attention should be paid to centering during use.
Question: How much is appropriate to insert the shaft into the coupling during installation?
Answer: Please select the length of the main body (coupling part) described in the product catalog. If the insertion amount is too short, the shaft may slip and the clamping part may be damaged; If the insertion amount is too long, it will be damaged due to shaft interference inside the coupling.
Question: Why is it necessary to install a protection cover around the coupling?
Answer: Due to high-speed rotation, accidental contact may result in injury or entanglement of gloves, towels, etc. In addition, for some reasons, parts may be damaged or debris may be scattered. Therefore, be sure to install the safety protection cover.
Question: What should I do if there is no matching shaft bore diameter?
Answer: Please select a product with changeable keyway width or available with keyway processing. MISUMI products are divided into MCSLCWK series (disc type), CPOC series (cross type) and MMJN series (claw type), etc.
Question: Is it a defective product that has difference in groove gap width?
Answer: Since the difference is within the dimensional tolerance range, there is no problem.
