Gears are used in all aspects of life, from bicycles to tiny watch gears, car transmissions, and even highly specialized surgical equipment. Gears keep the world moving. However, when they move, they often rub against each other, and if this friction is not managed,...
Heat Transfer Systems (HTS), also known as thermal fluid heating systems or hot oil systems, operate by circulating a fluid through a closed-loop system to transfer heat to and from various process equipment. These systems are widely used in industries for...
One of the first theoretical lessons you learn when you dive into the world of lubrication and lubricant analysis is that temperature generally harms these compounds. This is true, and many trainers in the area have at least a few slides dedicated to this point in...
Lubricants encounter negative influences throughout their working life, including load-induced shear stress, thermal degradation, water contamination, aeration, wear metal catalyzing, and contamination from dirt, chemicals, and incompatible lubricants and fluids....
Lubricants are the lifeblood of machinery, and every decision, from selection, purchase, storage, dispensing, and health management, plays a critical role in ensuring the reliable operation of essential machines. A minor oversight can lead to significant downtime,...
In my experience, flash point is one of the most misunderstood numbers on a product data sheet. Most people ignore it, as it is rare for oil system temperatures to approach the flash point range (typically >200°C). When it does become a concern, there is often...
Calculating a lubricant's Viscosity Index (VI) requires understanding how the viscosity changes with temperature. The VI is a numerical value that indicates how stable a lubricant's viscosity is with temperature changes. A higher VI means the lubricant maintains its...
What are Viscosity Index Improvers? Viscosity Index Improvers (VIIs) are additives that help maintain the viscosity of lubricating oils across a wide temperature range, ensuring consistent performance. This article will explore the nature of viscosity index improvers...
It is often stated that viscosity is the most important property of a lubricant, and with good reason. Film thickness—the separation between moving machine surfaces—is primarily dictated by the lubricant's viscosity under operating loads, speeds, and temperatures. For...
Fuel economy is a crucial aspect of modern vehicle maintenance and fleet management. With rising fleet fuel costs and ever-tighter environmental regulations, achieving better fuel efficiency has never been so important. The lubricant in use is often an overlooked...
