Ultrasound is an especially good tool for detecting bearing problems on slow-speed machines. However, there are some common misconceptions about how this is accomplished. The rules behind the processing of the acquired signal are the same for ultrasound or vibration analysis. A rolling element bearing’s Fundamental Train Frequency (FTF) or Cage Frequency is usually somewhere […]

In case you missed the first two installments of this article, be sure to check them out before jumping ahead to this last installment. In the first installment, we took a closer look at the reason for monitoring critical assets while in the second installment focused more on developing the oil analysis program as well […]

Consider how your vibration data collection instrument gathers information. This is a critical factor that can either streamline or prolong the data collection process within your facility. Typically, vibration analysts record and store an overall value (OA), spectrum (FFT), and time waveform (TWF) during each measurement. Some vibration hardware devices require separate measurements for each […]

In our previous blog, we discussed the: Shaft Alignment Measurement Mode: Multi-Point Method. In this blog, we continue with the next method: Uncoupled Sweep.  The Uncoupled Sweep Measurement mode allows you to measure uncoupled machines with ease. Start from any rotational position and take measurements by rotating the shaft with the S-laser in front of the […]

As part of our training program, we simulate various scenarios, to teach trainees how to see through a problem to a solution. To this end, the Soft Foot Analysis Form is a simple yet effective aid. Soft foot is machine frame distortion. It is evidenced by the movement of the machine shaft as the anchor […]

In the first installment of this series, Optimizing an Effective Oil Analysis Program for Critical Assets – Why Focus on Critical Assets? Part 1, we focused on the reason for monitoring critical assets while also diving into the other types of assets. For this second installment, we will focus some more on actually developing an […]

When acquiring new vibration equipment, it is important to delve into the genuine long-term cost of ownership, rather than fixating solely on the initial purchase price. The notion that the cheapest or most expensive option is always the wisest doesn’t hold true in this context. To make an informed decision, it is imperative to account […]

In our previous blog, we discussed the: Shaft Alignment Measurement Mode: Continuous Sweep Method. In this blog, we continue with the next method: Multi-Point.    The Multi-Point measurement mode is among the most versatile measurement modes as it allows you to measure under any condition. It lets the user begin the measurement from any rotational position and […]

When purchasing a laser shaft alignment system, consider the following things to ensure you choose the most suitable and effective solution for your specific needs: Accuracy and Precision: Look for a laser shaft alignment system with high measurement accuracy and precision. The system should provide reliable and repeatable results for precise alignment adjustments. Ease of […]

Our critical assets are the ones that get the most attention in our plants. They are considered the main drivers of production as without them, output can stop which directly affects the profitability of the plant. Quite often, these can be thought of as the heart of the operation as they need to be working […]

Selecting the appropriate machines for mounting wireless vibration sensors involves a thoughtful process that integrates criticality analysis and considerations of accessibility. Here’s a more detailed breakdown: Criticality Analysis Prioritize critical machines by identifying and prioritizing machines critical to your operational processes. These could be equipment with a significant impact on production, safety, or overall system […]

In our previous blog, we discussed the: Shaft Alignment Measurement Mode: EasyTurn™ Method. In this blog, we continue with the next method: Continuous Sweep.  The Continuous Sweep Measurement mode allows you to begin an alignment measurement from any rotational position. Simply rotate the shaft and let the tool record the points as you go around. […]

These 10 rights were taken from the book: Audit It. Improve It! Getting the Most from your Vibration Monitoring Program by Alan Friedman. Right Goals: Having clearly defined and achievable goals that may evolve over time. Right People: Having the right people in the right roles with the right condition monitoring training. Right Leadership: Inspiring continuous improvement. […]

Fast and Efficient Heating: Induction bearing heaters such as SURETHERM offer safe, rapid, and efficient heating, significantly reducing the time required to heat bearings compared with traditional methods. This efficiency enhances productivity by minimizing downtime during installation or replacement procedures. Precise Temperature Control: Induction heating provides precise temperature control, ensuring that bearings are heated uniformly […]

One of the largest power plants in the United States experienced issues with two out of three recirculating pumps, which are critical for generating power. Despite regular monthly vibration route data collection, the pumps were running louder than normal, indicating a potential problem. To avoid a complete failure that would halt power generation, the plant […]

In our previous blog, we discussed the: Shaft Alignment Measurement Mode: 9-12-3 The Classic Three-Point Method. In this blog, we continue with the next method: EasyTurn™.    The EasyTurn™ shaft alignment measurement mode allows you to begin the measurement from any location and take a total of three points. The points can be taken at […]

Measurement points are recorded at three fixed clock positions: 9, 12, and 3 o’clock. This is the classic three-point method which can be used in most cases. Below are some applications where this mode is preferred: Vertically-oriented alignments: When performing an alignment on a vertical machine the automatic inclinometer used to determine the shaft’s rotational […]

There are two primary types of balancing machines; a Soft Bearing Machine and a Hard Bearing Machine.  Both types have advantages and disadvantages. Here are the differences: Soft Bearing Balancer A soft bearing balancer allows the rotor ends to move freely in the horizontal direction of the balancing stand.  This type of balancer allows the rotor to turn […]

When monitoring the vibration data of a machine, an analyst will want to look at the Time Waveform (TWF) and the Frequency Spectrum or FFT (Fast Fourier Transform) output, as shown below. These two example plots are very useful for determining obvious failure modes, such as, an imbalance with a high amplitude value of Overall […]

Use ANSI Shaft Alignment Tolerances to help solve base-bound and bolt-bound situations. If a base- or bolt-bound situation presents itself during an alignment, take advantage of the outer limits of the tolerance envelope to help overcome the problem. It may be possible to optimally position the machine to meet the minimal ANSI tolerances and eliminate […]
