A maintenance strategy wherein machine adjustments and minor maintenance is performed by operators who are deemed to have unique knowledge about the equipment. It is a principal pillar of Total
Many people use one of these high frequency techniques to detect and monitor bearing wear. However, the location and mounting of the accelerometer on the machine will determine the ultimate
Mounting: Your accelerometer should be stud mounted. Magnetic mounts and handheld probes should not be used. The accelerometer should be mounted on a surface that has been spot faced and tapped to accept the accelerometer stud per manufacturer instructions. When it is installed, the stud should be tight, stretching the stud to ensure proper contact and coupling across the entire face of the accelerometer. Burrs or dirt on the face or a poorly drilled and tapped hole will degrade the signal, so be sure to use the appropriate tools. If you must use a portable sensor, be sure to use one of the stud mounting systems offered by several manufacturers.
For certain applications, automatic bearing lubricators provide an alternative to manual electric motor bearing re-lubrication. These self-contained units, which deliver lubrication to bearings
During a recent Meridium - SAP webinar titled "Optimizing SAP Maintenance Plans" produced by RealibilityWeb.com, attendees were asked: What percentage of your previous RCM/FMEA recommendations actually made it into SAP? The answers indicate reliability & maintenance professionals are still struggling to get the recommendations coming out of their RCM/FMEA studies into SAP for execution.
13% of the respondents answered that 76% - 100% of their recommendations make it into SAP 16% of the respondents answered that 51% - 75% of their recommendations make it into SAP 29% of the respondents answered that 26% - 50% of their recommendations make it into SAP 43% of the respondents answered that 0% - 25% of their recommendations make it into SAP

Measuring machinery misalignment with today's tools, particularly computerized laser alignment systems and well-designed bracketing, is no longer as difficult a task as it once was, when all you
While checking for Soft Foot with either dial indicators or a laser, use a set of feeler gages to measure the gap under each corner of every foot. This simple and quick step will identify if
That question seems simple enough, however the answer may be one of the fundamental causes for Planning and Scheduling efforts that fail to deliver their potential.
One of the most important and most often overlooked areas of maintenance and reliability improvement lies in the fundamentals. Many of the facilities that I visit are caught in a game of
You are taking vibration data on all of your critical assets and also all essential assets. Yet, you still feel overwhelmed and some assets are stretched beyond their data collection interval.
In the maintenance and reliability world we spend much of our time thinking and planning out ways to better maintain or redesign some equipment to make it last longer or be more reliable.
Maintenance and reliability engineers will happily (well, not happily) undertake a review of spare parts that are not classified as critical, yet they will shy away from reviewing items that are
