This blog post concerns rolling element bearings and not journal bearings. When a rolling element bearing begins to deteriorate the damage usually manifests itself in one of the races (either inner or outer) followed by the rolling element, and finally the cage. When the races begin to have defects these tend to excite the natural […]
Question: When is it OK to over-lubricate your bearing? Answer: NEVER!!!!, (almost) the exception is when high vibration exists. If you attended the SDT/LUDECA Acoustic Lubrication Workshops then you now understand grease as a lubricating mechanism. You understand that the Churning Phase of the lubrication task is inevitable, and long-term, detrimental to the health of […]
Reposted from People and Processes, written by Jeff Shiver CMRP, CPMM, CRL The CMRT exam is the leading credentialing program by the Society for Maintenance & Reliability Professionals (SMRP) for the knowledge, skills and abilities of maintenance and reliability technicians. The CMRT exam tests competency and knowledge of specific tasks within 4 domains: Maintenance Practices, Preventative […]
Guest Post by Bob Dunn from I&E Central, Inc. I had the opportunity use the Easy-Laser XT440 to assist a customer aligning a machine that had perpetually given them problems, with bearings always running hot. They had recently aligned the machine with dial indicators, but when we checked, it was off by .007, and this on […]
In most cases, when equipment is in failure mode, it begins to make sounds that are not commonly heard during normal operation conditions. Once this sound is heard a defect (at least one) is already present in the equipment. Using our vibration tools can assist in detecting the defect before that sound is heard with […]
There are 3 techniques that can facilitate your work in the field: the shielding technique, the covering technique and reflection management. 1. Shielding technique This technique greatly reduces the influence of interfering leaks. It consists in using a piece of cardboard or foam(*)… to create a barrier between the “parasitic” leak noise and the location […]
As Published by Solutions Magazine March/April 2018 issue by Ana Maria Delgado, CRL and Shon Isenhour, CMRP CAMA CCMP, Founding Partner at Eruditio LLC During the many root cause analysis (RCA) investigations we facilitate and coach, we notice some themes that continue to manifest themselves in the findings. Often, they are grouped under the heading […]
Guest post by John Lambert at Benchmark PDM Recently I have been seeing the P to F interval curve popping up a lot on my LinkedIn feed and in articles that I have read. It was a concept that I was first introduced to when I was implementing Reliability Centered Maintenance into the Engineering and Maintenance […]
1. A Change in the Quantity of Grease Consumed Maintenance departments track their grease consumption to monitor and control costs. A change in consumption is a sure sign that your lubrication program is on the right track. Most organizations are guilty of over-lubricating. Expect lower grease consumption as your program matures. Bad procedures lead to […]
In the 35+ years of experience that LUDECA has in shaft alignment, we have been asked this question many times. How long does it take to do an alignment? People in charge of scheduling have a tough task when allotting time for technicians to do an alignment with precision. In many cases they may just […]
