We've addressed the virtues of training numerous times on the pages of Machinery Lubrication and other Noria publications. Still today, we encounter a national workforce in the lubrication...
Like most of the Noria technical consulting team, I spend a considerable amount of time in plants. As a result, I see a host of different lubrication problems, but perhaps one of the most pervasive...
A popular misconception involving hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift. While a leaking piston seal can be the root cause of cylinder drift, the…
Does oil analysis prevent machines from wearing or failing? Of course not! Knowing a machine is wearing or that conditions exist leading to machine wear and failure are not factors of prevention....
Maintaining properly lubricated machinery is an important part of any lubrication program. Without administering lubricant at correct intervals with the proper amount, a machine can experience...
A facility manufacturing intermediate chemical compounds for plastics manufacture has a large number of air-cooled systems with numerous fans driven by electric motor and speed-reducing pulleys....
Food-grade, food-plant, NSF certified, FDA listed, USDA registered - the list of lubricant terms is endless. Sifting through the terminology, standards and best practices for properly lubricating...
Liberty Paper, a paper mill in northern Minnesota, manufactures linerboard from recycled corrugated containers. The mill runs 24 hours a day, 7 days a week. A Valmet paper machine operates at a...
Rolling-element bearings used in electric motors are at risk for various modes of failure if an incorrect maintenance or lubrication strategy is implemented. These include incorrect lubricant selection, contamination, loss of lubricant and overgreasing. This article discusses several effective strategies to minimize the likelihood of these failure modes.
During the early 1990s, an abundance of literature on lubrication was available, but the content of this literature did not provide a practical guide to setting up a lubrication plan or how to...
Selecting the right lubricant for machinery operations positively impacts the plant's bottom line. By providing processing equipment with correct lubrication, companies can extend equipment life,...
How can the stages of bearing failure in a plain bearing (not ball bearing) be detected on a turbocharger installed on a medium-speed engine burning heavy fuel oil? How can one detect the bearing...
Food-grade greases are used in various food-processing equipment and other industrial equipment applications. These include plain and rolling element bearings, joints, linkages and slides,...
The ISO Subcommittee on Condition Monitoring and Diagnostics of Machines (TC108/SC5) is developing a standard on used oil analysis. The working group on tribology-based condition monitoring is...
