By on July 20, 2017

I recently taught alignment training at a gas compression site.  These were sharp technicians, and they keep these large gas compressors in excellent shape.  We went out to check alignment between the engine and compressor.  It was great just as I expected, because compressing gas is their only product. So I asked if they had […]

Precision Shaft Alignment with Adjustable Chocks

| | |

By on May 17, 2017

We have written, here on the VibrAlign blog, about adjustable chocks used in place of shims for vertical adjustment and machine support. A recent experience at a customer site prompted this article, to share a simple tip that could save valuable time and effort. The customer was using vertical jack bolts while viewing live alignment […]

Time is a commodity maintenance personnel typically have in short supply. We hear quite often, in our on-site Shaft Alignment Best Practices training classes, “………. doesn’t give us enough time for a proper shaft alignment”. So how can maintenance personnel get more time for shaft alignment? Stop wasting it! I had the pleasure of working […]

Positive/Negative

| | | | |

By on February 7, 2017

When we align equipment, we are aligning the rotational centerlines of the shafts. We have a stationary machine and a moveable machine. In most cases the stationary machine’s center of rotation is the target and reference for all measurements and corrections of the movable machine. When reading laser or dial indicator values, the terms of […]

By on January 25, 2017

When training clients to use VibrAlign’s Verti-Zontal Alignment Process we show taking the 3rd measurement at a horizontal position, typically at 3 o’clock. This is simply for expediency and is NOT a requirement as Fixturlaser Shaft Alignment Systems can take measurements at any position due to the inclinometers in M & S sensors. If possible […]

Soft Foot Concerns In The Stationary Machine?

| | |

By on January 27, 2016

VibrAlign has numerous blogs on soft foot and the frustration that goes along with not eliminating it. Repeatability (or the lack of) can be a major issue. Vibration analysis will pick it up if it is severe enough. When performing a precision shaft alignment most, if not all, soft foot will be eliminated in our […]

By on December 24, 2015

Rim & Face, Angle & Offset, Parallel & Angular Deviation, Parallel Offset, thousands of inch and mils! What does it all mean? Actually it’s pretty much the same thing, though not exactly. I’ve been a VibrAlign Technical Trainer since 2008 with training classes in a variety of industries and with students previously using other methods […]

Proper Coupling Application, Installation and Maintenance

| |

By on September 16, 2015

Precision maintenance personnel ensure that rotating machinery is aligned well beyond excellent shaft alignment tolerances, but overlook other crucial elements that affect the operation of the machines. One of these elements is the coupling. The coupling is where the “handshake” between the driver and driven machine takes place. The coupling assures consistent power transfer and […]

Machine Tool Spindle Alignment

| |

By on September 10, 2015

Precision shaft alignment of general industrial equipment, such as pumps and compressors, requires precision. But alignment of machine tool spindles and components requires an even greater level of accuracy. Precision alignment of machine tool spindles can improve product quality & finish, reduce scrap, re-work, broken tooling, and improve cutting tool life. There are numerous configurations […]

Shimming when there are more than four feet on the moveable element.

| |

By on August 4, 2015

  When more than four feet are on the movable machine, it is necessary to shim under the additional feet. How do we determine what amount of shim is required to properly support these feet? This is debatable. Some would say that it is necessary to calculate the needed shims. Others might say “Why bother? […]

“5 Effects of Misalignment”

| | | |

By on May 19, 2015

One of the common misconceptions in industry is that precision shaft alignment is not needed when using flexible couplings. Studies have show that nearly 50% of all machine breakdowns is due to misalignment. So what happens to misaligned machines? Check out the recently added video to the VibrAlign You Tube Channel titled “5 Effects of […]

By on April 30, 2015

A dowel pin, in its simplest form, is a hardened steel shaft, usually very short, and can be straight or tapered. It is often used in machinery for: Precise locating of machinery components, such as the top half of a pump, gearbox components, line shaft bearings, etc. Dowels are usually located in diagonal corners of […]
