What is considered a good foot-to-base fit for alignment?

A good foot-to-base fit for alignment should be less than 0.001 inch. This measurement indicates an extremely tight and precise fit, which is crucial in ensuring that the machinery operates efficiently and reliably. A fit this precise reduces the risk of misalignment over time due to wear, thermal expansion, and other operational stresses that could lead to increased vibration and premature equipment failure. Keeping the alignment tolerances this strict not only improves the performance of the machinery but also extends the lifespan of the components involved. This level of accuracy is essential in high-precision applications where any misalignment could result in significant operational issues.
