In shaft alignment, machines that run hot often have thermal growth targets. Thermal targeting simply means that the shafts may be misaligned while at room temperature, but as they heat…

Previous blogs have defined thermal growth of rotating equipment and discussed several different methods to calculate the cold (ambient) alignment targets to compensate for thermal growth. The OL2R program (Off Line…
Read MoreIn my post “How Does Calculating Your Own Alignment Targets Work?”, I discussed using a hot check to determine proper alignment targets. Thermal growth is not rocket science. However, it…
