We have several times discussed the differences between coupling alignment tolerances and precision shaft alignment tolerances (see links below). As stated in those text the coupling manufacture’s ...

Proper shaft alignment of directly coupled machines has proven to be one of the greatest money savers for machinery-intensive industries over the last 25 years. When poorly done, usually for lack of ...

Installation overview: Even if a coupling is properly selected, poor installation can cause failures, staying within the recommended misalignment ratings of that coupling at installation is critical.

The majority of precision shaft alignments are relatively close coupled where there are only a couple of inches between the shaft ends of the driver and driven elements. Close coupled alignment ...
