A Proven Electric Motor Regreasing Program

By Jerry S. Honeycutt, Tennessee Valley Authority

One of the most asked questions of grease lubricated motors is, what is the correct interval to regrease the bearings? This is usually followed by two questions, 1) how much grease should be added? and 2) what is the correct method for grease addition?

Best Practices Lubrication for Universal Driveshaft

by Paul Dufresne, CLS, CMRP, CPMM, Trico

In tough working environments, machine reliability can be difficult to maintain - especially when contaminants threaten bearings and components. One such application is the universal driveshaft - a component that faces neglect due the extreme conditions and locations where they are used.

Building A Lubrication Program - By Using the Five Rights, You Won’t Go Wrong

by Ray Thibault, CLS, OMA I & II

This article will examine the use of the five rights of lubrication - which are Right Type, Right Quality, Right Amount, Right Place and Right Time - all of which are important in the development of a highly effective lubrication program. Many companies fail to realize the importance of lubrication and the application of these five basic concepts to achieve world class machinery reliability. Each will be examined in detail, along with a summary of best practices, including procedures in the selection of the optimal lubricant supplier.

 

Clearing the Confusion

Simple is always better. And solutions really don't come any simpler than this one.

Imagine eliminating virtually any chance of cross contamination in all of your grease applications. The solution is as simple as switching the type of grease gun you use. 

That's it.

Creating A Sustainable Operator Driven Lubrication Program

The position of 'oiler' or 'lubricator' has been all but eliminated in most companies. There has been a number of responses to this change however one of the most effective is to create a documented and well defined Operation Driven Lubrication program.

This presentation provides details and case studies of successful Operator Driven Lubrication programs (ODR) and how it can fit into a more comprehensive Performance Management Program that breaks down silos and aligns people toward the aim of the organization.

Effective Guidelines for Implementing a Well-Engineered Lubrication Program

by Kevan Slater, CLS

A global recession, combined with intense global competition, is forcing many companies to review and search for a "proven" method of reducing their overall maintenance costs while increasing the reliability of their aging equipment. Despite the continuous preaching of the benefits of implementing an effective lubrication program, many organizations still lack the formal direction and understanding required. This article will provide a proven methodology and direction to obtain the benefits of a Well-Engineered Lubrication Program.

 

Electric Motor Bearing Greasing Basics

One of the most important components of any electro-mechanical maintenance program is the lubrication of bearings. Yet, this vital aspect of preventive maintenance remains one of the least understood functions of maintenance. There is constant debate concerning whether a bearing should be ‘flushed,' a limited amount of grease added, how often or if the motor should be operating or tagged-out. Many motor manufactures outline the preferred, and safest, method for lubricating electric motor bearings. There are specific physical properties for this process in the motor bearing housing and in order to protect motor windings from contamination.

Energy Conservation and Precision Machine Lubrication

by Mike Johnson, CMRP, CLS, MLT2

Machine lubrication practices offer a multitude of opportunities for energy conservation. Some of those opportunities are obvious and quantifiable, and some are not.

Energy Savings Through Task-Specific Lubrication Reliability

Streamlining Lubrication by Eric Rasmusson

With most plants today facing increased pressure of competition - and some even fighting for survival- the advantages of a task specific lubrication reliability system are too great to be ignored any longer. Along with several other reasons, energy savings is one major benefit of unlocking untapped potential in a large number of facilities through better lubrication practices.

 

Helpful Hints to Increase Reliability Through Lubrication

by Brian Thorp, CLS, MLT II

You always hear about establishing goals, setting ISO code cleanliness, getting some training, setting up an oil analysis program, and all the other things you need to do to have a successful lubrication program.  In a perfect world we are set and ready to go.  Well, I hate to be the one to tell you, but really there isn’t a ‘one size fits all’ plan out there.  So let’s have a practical discussion about some of the methods and equipment that can be used to achieve, and then maintain, our vision.

Increase Pump Uptime, Decrease Costs With Water Management System For Mechanical Seals

by Chris Rehmann

Rising cost and shrinking availability of clean water for operating industrial pumps are of concern to many plant managers, as is as the high cost of treating this water for disposal.  For over a half-century, the accepted method of providing cooling and flush water for mechanical seals and packing has been to pipe plant water through the seal or packing, and then to drain.  Under this scenario, the normal consumption of water is 1.7 million gallons of water per pump, per year.

Industrial Lubricants Reduce, Re-use & Recycle

Industrial Lubricants - Reduce, Re-use & Recycle

Summary

While lubricants are a relatively minor cost for many production operations, the cost associated with unscheduled break down of equipment as a result of lubricant failure can be significant. For example, an unexpected outage of a power station due to malfunctioning of a hydraulic control system would be extremely costly. 

It is therefore necessary for users to ensure that the condition of the lubricants in the equipment is always within operational specifications. 

Like many industrial components, over 80% of lubricants are being disposed of prematurely. Adhering to some simple guidelines can significantly extend the useful life of most lubricants resulting in reduced consumption, extended machine life, and minimized unscheduled shutdown maintenance.

Maintenance of Hydraulic Systems

The right way to perform maintenance on a hydraulic system utilizing the Maintenance Best Practices

Most companies spend a lot of money training their maintenance personnel to troubleshoot a hydraulic system. If we focused on preventing system failure then we could spend less time and money on troubleshooting a hydraulic system. We normally except hydraulic system failure rather than deciding not to except hydraulic failure as the norm. Let's spend the time and money to eliminate hydraulic failure rather than preparing for failure. I worked for Kendall Company in the 1980's and we changed our focus from reactive to proactive maintenance on our hydraulic systems and thus eliminating unscheduled hydraulic failure. We will talk about the right way to perform maintenance on a hydraulic system utilizing the Maintenance Best Practices.

Oil Mist Lubrication for Positive Displacement Blowers

Looking Into The Mist by Heinz P. Bloch, P.E.

A reliability engineer was trying to explore the viability of a project to equip a number of Roots-type rotary lobe blowers with oil mist. He had looked up a number of web-based papers, OEM manuals, and a relevant text ¹.
