Can a Mercotac connector be mounted by the upper bushing?
Yes, in special circumstances. In the case of a vertical mounting (or a mounting somewhat vertical) where the Mercotac connector needs to be mounted below the rotating device, the Mercotac connector will need to be attached by the upper bushing into the mounting shaft or collar. In this case the body and lower bushing will be stationary and free floating. It is very important that the mounting be straight and centered so there is zero or minimal lateral motion or wobbling of the body, less than .005 inch TIR is recommended.
