We often get asked why we don’t input a coupling diameter when performing a precision shaft alignment with the ACOEM laser alignment systems. The coupling diameter (or more correctly sweep of a face dial indicator) is only required when doing a rim and face dial indicator alignment or when the user wants to know the…

These types of couplings are quite common in industry, and there are various companies producing similar types of couplings. They are capable of transmitting large amounts of torque in a reasonably small space. They also do not require lubrication, and are quite easy to install, in most circumstances. These attributes make them quite desirable in…

Millwrights and mechanics know the benefits of using jack bolts to precisely control the horizontal position of the movable machine when performing a precision shaft alignment. However, we also see the tendency to tighten the jack bolts, on both sides of the movable machine, either before or after tightening the hold down bolts. Tightening jack…

Most aligners are familiar with a bolt bound situation, which occurs when the motor cannot be moved enough to achieve proper horizontal alignment. A base bound condition occurs when a motor cannot be lowered sufficiently to achieve proper vertical alignment. Here is an example. During a customer’s recent pump replacement, the motor was left in…

When performing a precision laser shaft alignment, it is best to add or remove shims exactly as the display unit indicates. There are circumstances when this may not be possible due to your assortment of shims, or when you want to “fudge” your shims slightly to keep the total number of shims low. (Clink for…

With the availability and decreasing prices of technology to help diagnose rotating machinery health, machine failure should be a diminishing concern. Thermal imaging cameras can be expensive; however, these cameras have very detailed diagnostic abilities and high resolution. Reduced cost Thermal Imaging has recently become available through various sources. I recently purchased an infrared camera…
