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.

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.
