Installation Errors Part 4 – Hold Down & Jacking Bolts

| | | | |

By on September 20, 2018

Correct fastener torque is important for proper assembly of rotating machinery components to machine bases. Proper torque insures that the fastener will perform as designed. This will in turn help your machine to perform as designed. Hold down bolts and jacking bolts are typically manipulated while performing a precision shaft alignment. These are often the […]

Vertical Alignments Using the Fixturlaser NXA Pro OmniView

| | | |

By on September 14, 2018

Many modern laser alignment systems include inclinometers that aid in the alignment process. Inclinometers, however, don’t work on vertically oriented machines. These include vertical “C” faced machines as well as vertical machines with feet. This meant that vertical machines required a 180-degree swing for accurate measurements and sensors were positioned the old-fashioned way by aligning […]

By on September 13, 2018

Accelerometers by nature are sensitive tools. This sensitivity is heavily influenced by how the sensor is mounted. Standard accelerometers are mounted several ways based on need and application. Typical route-based data collecting will be done with a rare earth magnet. The magnet can be either flat or a two-pole type. This provides good data with […]

What is the Difference between Unbalance and Runout?

| |

By on September 5, 2018

Unbalance and runout are two terms that we hear frequently in the predictive maintenance community. Both unbalance and runout can be serious issues and need to be addressed to prevent inefficient functioning and damage to machines. Unbalance occurs due to corrosion, erosion of the fan wheel, or if a correction weight is removed. Runout occurs […]

How to Measure Your Machine’s RPM

| | |

By on September 4, 2018

Determining the RPM (revolutions per minute) of your machine is an important part of conscientious condition monitoring. Significant loss of time and productivity can occur if your machinery is not operating at the correct RPM. That’s why it is imperative to be able to quickly and accurately determine the RPM. In this post we will […]

Setting Tolerances in Fixturlaser Shaft Alignment Tools

| | | | | |

By on July 30, 2018

Fixturlaser Shaft Alignment Tools come pre-programmed with generally accepted industry tolerances for electric motor driven machinery.  These tolerances are based on the motor RPM and will give you an “endpoint” in the alignment process (based on the measured offset and angular misalignment at the center point of the coupling in both the vertical and horizontal […]

Using the Smart Machine Checker as a Lubrication Tool

| | | | |

By on July 10, 2018

The Fixturlaser Smart Machine Checker (SMC) is a great mechanic’s tool, for evaluating the overall health of rotating machinery.  But did you know it’s also a lubrication tool for greasing bearings?  Let me explain. One of the vibration measurements in the SMC is called Bearing Defect Factor.  The Bearing Defect Factor is a measurement of […]

Installation Errors Part 3 – Proper Torqueing of Hold Down Bolts

| | | | |

By on June 27, 2018

One of the most under-rated procedures of the precision shaft alignment process is the TIGHTENING SEQUENCE of the hold down bolts on the movable machine. Also, tightening the bolts to proper torque specifications is many times considered unnecessary and is just not typically done. Tightening sequence and proper bolt torque are critical to the performance […]
