Industry rides on a film of oil. The oil’s viscosity bears the load and defines the extent of clearance achieved between working surfaces. Sometimes that clearance is thick and bountiful, and other times it is deflated or extinct. Without viscosity, most machines would rapidly self-destruct with mechanical friction and wear.

There is also a well-known penalty and reliability risk from too much viscosity. Like most things, the selection of a lubricant’s viscosity must be optimized to enable needed protection and disable the danger from excessive viscosity. For instance, too much viscosity can cause churning losses and excessive heat generation from molecular friction. It can also impede lubricant movement and flow to lubricant-hungry surfaces.

One of the most famous disadvantages of too much viscosity is high energy consumption. In recent years, we’ve seen automaker-specified viscosity being lowered in crankcase service from 5W40 to 5W30, and now in some cases to 5W20. These changes are all for the sake of energy conservation.

Of course, the primary driver for energy conservation is not to save money on fuel or electricity but rather to reduce the consumption of fossil fuels, which emit harmful gases (carbon dioxide, nitric oxides, hydrocarbons, etc.) into the atmosphere as a byproduct of combustion.

The lubricant Optimum Reference State (ORS) is a critical concept in the journey to world-class lubrication and enhanced machine reliability. In short, it is the prescribed state of machine configuration, operating conditions and maintenance activities required to achieve and sustain specific reliability objectives. Lubrication excellence is achieved when the current state of lubrication approaches that of the Optimum Reference State. If you don’t understand the ORS, you probably don’t understand the most fundamental concepts in machine reliability.

Lubrication attributes of the ORS are not widely known by equipment builders, lubricant suppliers and maintenance organizations. Many user organizations falsely conclude that their machines are already fitted with the necessary accessories and components that enable reliability to be achieved. Sadly, of the hundreds of machine service manuals I’ve seen in recent years, it is rare to find practices described close to the ORS. In a typical plant, it is equally rare to see machines fitted with ORS-compliant lubrication components and technicians performing ORS-compliant lubrication.

There are many different attributes of the Optimum Reference State. These attributes relate to people preparedness, machine preparedness, precision lubricants, precision lubrication and oil analysis. Achieving the ORS almost always involves change or modifications. For instance, you can’t get optimum filtration unless you install the optimum filter. You can’t have optimum oil samples unless you install ORS-compliant sample valves in the optimum location. Then, of course, you need to pull the sample using ORS-compliant procedures at ORS-compliant frequencies.

Costly particulate contamination slowly degrades and jams machine components causing product defects, shorter machine life., increased production downtime and decreased energy efficiency. Even the smallest amount of water, or the most microscopic particles, can ·eventually grind a machine to a halt. Yet, maintenance has historically been a ·reactive type activity .. When a machine breaks down, maintenance personnel give the failed components the “4R Treatment”- that is remove, repair, rebuild and/or replace. When evidence suggests that material degradation and/or deterioration is taking place at an accelerated rate, the cause has been determined and. action taken to correct the problem. In today’s world when there are increasingly complex- systems., maintenance personnel must supplement such traditional reactive maintenance Practices with proactive methods that can identify aberrant root causes of failure long before materials or component performance degradation occurs. No maintenance discipline has previously taken the micro view on machine damage concentrating on the· causes instead of the symptoms of wear. Proactive maintenance is that discipline, and it is quickly being recognized worldwide as the most important means of extending machine life.
