It is both possible, and desirable, to minimize the negative effects of soft foot. While it may be difficult to completely get rid of soft foot, it can typically be reduced to a few mils, if the following techniques are used. PREPARATION AND CLEANLINESS CLEAN! If you remove the motor, wipe the feet clean, before…

Most industrial maintenance mechanics who are involved with precision shaft alignment are familiar with the phenomenon of soft foot. From an alignment standpoint, soft foot causes: Changes in alignment values, between when the hold down bolts are loose, and when they are tight. Non-repeatability in alignment measurements, especially if the bolts are not tightened in…

Most laser alignment tools include a soft foot function. However, in truth these tools haven’t measured ACTUAL soft foot, instead they have measured the EFFECT of soft foot at the shaft or coupling as that is where the laser heads or sensors are mounted. While the EFFECT of soft foot is important, correcting the ACTUAL…

It’s no joke that many machines operate with high levels of vibration due to soft foot. These same machines often have a decreased life span due to this condition. Soft foot is a condition that should be eliminated during the precision shaft alignment process, if you’re performing proper alignments at all. This condition can manifest…
