Lubrication Tip
Measuring Lubrication film thickness in double-roll spherical roller bearings.
One of the most common bearing installation faults that affect lubrication film thickness is the installation and set up of the tapered bore, double-row spherical roller bearing using a split tapered adapter in a mounted unit, i.e. Pillow Block Bearing.
The tapered adapter is used as a wedge device to hold the inter race of the bearing on to the shaft. All bearing manufactures have recommended clearances for applying this type of bearing. This type of bearing in a pillow block housing is very common on larger fan applications and is a very popular style for many other applications.
If the tapered sleeve (adapter) is drawn up to far by over tightening the spanner nut (a very common practice) the internal clearance of the bearing will be removed thus reducing the lubrication film thickness. Even though these bearings are running with no apparent fault or vibration alarm detected by using normal FFT technology the reliability of the machine has been put into jeopardy because the operator cannot see the film thickness problem. Lubrication film thickness can be measured to determine the true condition of the bearing during start up without setting a baseline and treading. Differentiating bearing surface damage faults and lubrication film thickness faults is powerful knowledge.

Root Cause Analysis (RCA) Tip
As Eli Goldratt stated in “The Goal”, an expert is not someone that gives you the answer, but rather someone that asks you the right questions. This concept is relevant in RCA because one of the greatest values of RCA, is the learning by the team members when they have to ask the right questions, and search for the answers themselves. RCA approaches that provide the answers (which they cannot possibly provide all the answers, everywhere), eliminate the element of learning derived from RCA. This all depends on what the goals of the organization’s RCA efforts are.

Maintenance Tip
When using Induction Heaters to heat bearings, make sure that the tops of the vertical post are clean; this will make for better contact of the horizontal crossbar. Applying a thin coat of the petroleum jelly will also help. This prevents vibration from occurring and possibly false brinelling the work piece being heated.

Infrared Tip
Simplify Thermography Electrical Inspections
There are a few basic aspects of thermal problems you want to capture while out in the field. First, get the best thermal image you can.
• Check to see you have the correct image composition?
• Can you see the hot spot with enough resolution; are other phases or other reference points within the frame needed?
• Are you close enough to make a reasonable measurement?
• Check with the vendor about the distance to spot size specification?
• Is the temperature scale set properly?
Most cameras have an auto exposure setting. In some cases a hotspot is so severe that the automatic exposure will select the lowest gain resulting in an image with little contrast. Better to let cooler portions of the image go out of range then hot areas.
Don’t set emissivity value below 0.5. While all systems allow lower settings most users will not be able to make an accurate measurement due the complex nature of shiny objects.
Record the load. After finding a hotspot it is critical to understand the severity of the fault. A 5° temperature rise at 5% load maybe more critical than a 50° C rise at 100% load. Check the load.

Maintenance Tip
When kitting and staging parts for jobs, it is very helpful to attach a tag with the work order number printed clearly on it to BOTH the equipment and the kit. This makes it easy for the craftspeople to match the parts with the job. Bright orange tags work especially well.

Sensor Tip
Selecting Range of 4-20 mA Velocity Transducers
In selecting a 4-20 mA velocity transducer, ideally the user should be able to answer the following three questions:
1) What is the normal overall vibration level of the machine?
2) What is the limit for unacceptable vibration?
3) Is over-range capability for trending desired?
If the user does not have answers to any or all of these questions, the ISO standard can be of assistance in determining the best 4-20 mA velocity transducer. Smaller machines (under 100 HP) can likely be monitored using a full-scale range of 0.5 IPS peak to cover most monitoring and trending needs. Machines over 100 HP would usually be best monitored using a transducer with a full-scale range of 1.0 IPS peak.
