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.

Is there any reference available for lateral misalignment and angular misalignment of the product?

Lateral misalignment, angular misalignment and axial amplitude are all single allowable values. If there are multiple deviations at the same time, the allowable value of each deviation will be reduced to 1/2 of the original value.

What are the product features?

The middle of the coupling is connected with a cross slider, which can be disassembled freely. Large radial and angular deviations are allowed.

Is there a keyway machining for the inner hole of the product?

Additional keyways can be machined on the product body. Please refer to MISUMI manual and website.

Do I need to assemble the product myself when it arrives?

The products are shipped from different places and may arrive in bulk, so please just put them together yourself.

Product Overview of Flexible Shaft Couplings

・Characteristic of Flexible Shaft Couplings
Flexible Shaft Couplings is a part of which purpose is to connect two different rotating bodies (motor shaft, ball screw, etc.) and transmit torque.
Protects equipment by absorbing axial deviations (eccentricity, declination, and axial amplitude) that occur between rotating bodies.
In the event of an overload, the Flexible Shaft Couplings is first damaged and the connection is released to protect the power unit and the entire device.

Product Features of Flexible Shaft Couplings

By connecting a cross spacer in the middle of the Flexible Shaft Couplings, it can be freely disassembled and installed.
The spacer uses PA66 and has excellent wear resistance, corrosion resistance, and electrical insulation.
The sliding design compensates for radial and angular deviations more effectively.

Example Use of Flexible Shaft Couplings

Precaution of Flexible Shaft Couplings

Operating Temperature of Flexible Shaft Couplings: －20℃～80℃. d₁、d₂
Eccentricity, declination angle and axial amplitude are all allowable values of a single term. If multiple deviations occur at the same time, the allowable value of each deviation is reduced to 1/2 of the original value.
