Prior to installing a coupling (new installation or replacing an existing unit) it is important to inspect the condition of the shaft. If the shaft is sufficiently gouged, marred or otherwise distorted it may need to be dressed (reworked) prior to installing the coupling. During laboratory testing of the coupling to shaft interface we found that a deformed shaft can reduce the torque capacity of the joint. It is important to understand that the joint will only be as strong as the weakest link in the system.
An example of a shaft that needs to be dressed prior to
coupling installation is shown above.
Recommended Follow On Reading: In addition to inspecting the shaft for damage prior to coupling installation, it is also important to inspect the shaft keyway and key for damage as well. The following is an article on shaft keyway damage: Shaft Keyway Damage
