Roughing In Before Precision Shaft Alignment

| | | | |

By on June 1, 2017

Some people believe that precision laser shaft alignment has evolved to the point where pre-alignment steps, such as roughing in the alignment with a straightedge, are no longer needed.  Well, quite frankly, those people are wrong! The reason for roughing in the alignment has little to do with how accurately the lasers/sensors measure.  It has […]

Clean Your Rotating Machinery

| |

By on April 13, 2017

Everyone knows that keeping rotating equipment clean and free of debris and dirt will prolong the operational life allowing for maximum efficiency and performance.  Bearings, seals and other components will last longer and perform better plus repairs and alignments will be faster and easier. Motors, pumps and machinery with excessive dirt build-up will fail more often […]

Maintenance Strategies: Part One

| | |

By on January 4, 2017

In the current highly competitive global economy we live in, there is always a drive to get the competitive edge. One way is to develop a maintenance strategy that will improve safety, meet production goals, increase uptime, increase plant efficiency and thus increase plant profitability. There are four basic maintenance strategies: Breakdown Maintenance Preventive Maintenance […]

Alignment Considerations of Machines with Stiff Elastomeric Couplings

| | | |

By on December 28, 2016

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 […]

By on December 21, 2016

As a Millwright, Service Technician or any type of field or in-house Mechanic, we understand there is one main goal that we have in common, which is to keep the equipment running.  This includes repairing and minimizing downtime in the event of an unpredicted failure or breakdown.  Although it’s important to make repairs and perform […]

Three Major Contributors to Equipment Failure

| | | |

By on August 24, 2016

Past maintenance & production issues found in the industrial or manufacturing environment are still prevalent even in today’s equipment reliability focus. The major contributors to equipment failure remain the same, misalignment, unbalance and assembly errors. Another is lubrication, Mr. Stan Riddle addressed this in one his blogs “Machinery Vibration Problems part 3 – Lubrication”. Let’s […]

Reduce Force to Maximize L10 Bearing Life

| | | |

By on August 17, 2016

Simply put, L10 bearing life is the number of service hours that 90% of bearings will survive or conversely 10% of bearings will have failed. L10 life: is the preferred term in specifying bearing life and is defined by The American Bearing Manufacturers Association (ABMA). A bearing life equation is: This calculation assumes proper installation […]

MACHINERY VIBRATION PROBLEMS AND SOLUTIONS, PART 5, MECHANICAL LOOSENESS

| | | |

By on August 3, 2016

Mechanical looseness is a very common machine vibration diagnosis.  It is often overused-becoming a “catch all” category for undiagnosed vibration.  It can be caused by a multitude of things that may seem to have no relationship to each other, such as:   Loose bolting                                               Coupling looseness or backlash Belts Too Loose                                           Cracked welds Improper bearing […]

What’s the Point of Precision Shaft Alignment When We Use Flexible Couplings?

| | | | |

By on July 21, 2016

This is a common misconception in some industries surrounding flexible couplings. Some maintenance and production individuals believe that flexible couplings are designed to allow for a few degrees of misalignment.  This is not quite the case.  While flexible couplings do tolerate some amount of misalignment, this is not their intended purpose.  The greater the misalignment, […]

Low Cost Thermal Diagnoses of Misalignment and Machinery Health

| | |

By on June 29, 2016

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 […]

MACHINERY VIBRATION PROBLEMS – PART 4 BEARINGS

| | | |

By on June 6, 2016

  In industrial machinery, the centerpiece of vibration analysis is the ability to detect bearing problems BEFORE the bearing fails.  Even more beneficial is detecting the root cause of a bearing problem before damage is done. The bearing really is the heart of the rotating machine.  There’s a plethora of bearing types and designs. There […]
