Send us Fan Mail Rolling bearings rarely fail—only about 0.35% do—but when they do, lubrication is almost always the culprit. In this episode of Perfecting Motion, Bernhard Dreisser and Daniel Merk of Schaeffler explain why grease deserves to be treated as a fifth design element, not just a consumable. They unpack the concept of "Lifetime Solutions," tracing how First Fill decisions ripple across a bearing's entire service life, why the right additive package can extend bearing life by over 60%, and how automated Smart Lubrication systems are freeing maintenance teams from hours-long relubrication rounds. Along the way, they dig into real numbers—from calcium sulfonate complex grease advances to service-life comparisons at 120°C—and explain how closed-loop engineering keeps lab testing honest against real-world field performance. Our host, Marc Ingram, of Ingram Tribology, take a  practical look at how tribological expertise translates into uptime, sustainability, and lower total cost of ownership on the plant floor.  Our Guests: Bernhard Dreisser, Schaeffler Bernhard Dreisser is Global Business Development Manager for Lubricants at Schaeffler, where he works on the company's Arcanol rolling bearing greases and broader lifetime lubrication solutions.

Send us Fan Mail  In this episode of Perfecting Motion®, we sit down with a lubricant formulation and tribology expert whose work spans the full value chain — from base oil and additive chemistry to tribometer design, customer training, and future mobility applications. The conversation opens with what makes lubricant formulation genuinely difficult: not the chemistry in isolation, but the constant trade-offs between competing performance requirements, cost constraints, and application realities. From there, we explore one of tribology's most persistent challenges — the gap between laboratory measurement and real-world behavior. Tribometers are powerful tools, but only when the contact conditions, materials, and loading regimes are chosen with the right contact situation in mind. Our guest explains how to think about test method development, what accelerated tests can reliably tell us, and where overclaiming becomes a professional hazard. The episode also covers the human side of tribology: teaching complex concepts to customers and cross-functional teams, building labs that draw on chemistry, metallurgy, and mechanical design together, and whether AI and computational tools are changing day-to-day formulation work in meaningful ways. The closing discussion looks ahead — across research, formulation, testing, standards, and future mobility — to ask what will genuinely transform over the next decade, and what will remain stubbornly, usefully the same. For anyone working in lubricant development, testing, or industrial training, this episode offers a clear-eyed look at what rigorous tribology actually requires, and why getting it right has never mattered more. Our Guest: Dr. Rai Notay earned his PhD in Mechanical Engineering from the University of Leeds, specializing in engine tribology.  Rai is currently the Senior Tribology Research Engineer at Lubrizol in the UK, Rai conducts advanced tribology research in industrial lubricants and powertrain technology to enhance efficiency and durability.

Send us Fan Mail In this episode of Perfecting Motion®, Debottam Bose — a bearing and lubrication application engineer at Vestas with experience spanning steel plants, heavy industrial machinery, and offshore wind turbine drivetrains — shares what decades of failure investigation and field engineering teach you about reliability at scale. The conversation moves through the fundamentals of large bearing application engineering, the discipline of root cause analysis under pressure, and the underestimated role of lubricant selection in determining whether critical components survive or fail. Debottam draws on lessons from some of the harshest industrial environments — converters, casters, rolling mills — and explains why those lessons transfer more directly to offshore wind than most engineers expect. The episode also examines offshore wind as a maturing industrial technology: why standardization matters as much as innovation, how field failure data must feed back into next-generation turbine design, and what skills the next generation of tribologists will need as mechanical systems grow larger, more remote, and more closely monitored. Whether you work in renewables, heavy industry, maintenance engineering, or lubrication science, this episode offers a grounded, field-tested perspective on what keeps large machines running — and what we lose when they don't. Our Presenter:  Debottam Bose brings over 17 years of hands-on expertise as a Bearing and Lubrication Application Engineer, specializing in rolling bearing design, lubricant selection, and large-size bearing testing. He has deep experience across grease testing and specification, bearing inspections, and failure root cause analysis — and has applied that knowledge in some of the most demanding industrial environments in the world, including blast furnaces, sinter plants, steel casters, rolling mills, and offshore wind turbines, both direct-drive and geared platforms. Throughout his career he has worked directly with customers to solve complex application challenges, develop new products, and present technical findings — making him equally at home in the lab, on the plant floor, and in front of an audience. Today we're excited to have him share his insights on bearing and lubrication engineering in heavy industry.  For more information on STLE, please visit https://www.stle.org/ If you have an idea for our podcast, or interested in being a guest, please Email STLE Director of Professional Development Robert Morowczynski at [email protected] .   Also, we love your feedback, please take a minute to provide us with your thoughts at Perfecting Motion Podcast Feedback or Email us at [email protected].

Send us Fan Mail This podcast episode dives deep into the persistent and often misunderstood issue of micropitting in gears, guided by expert insights from Ben Wainwright. The conversation begins by defining micropitting and examining how it manifests in real-world applications, asking whether it remains a practical concern in modern gear systems and what fundamental factors—such as lambda ratio, surface roughness, and contact conditions—drive its formation. We explore how micropitting should be properly characterized, which surface finishes are most effective at reducing risk, and the complex role lubricants play, including whether antiwear and EP additives mitigate or inadvertently promote damage. The discussion then turns to testing: how micropitting is currently evaluated, whether today’s tests truly reflect field failures, and what an ideal test might look like if designed from first principles. The episode closes with practical guidance for gearbox designers, common misconceptions still seen in industry, trusted rules of thumb, and a forward-looking question on whether micropitting is something we will ultimately engineer out—or simply continue to manage.  Our Guest: Benjamin Wainwright completed his studies in mechanical engineering at Imperial college London in 2017. During his undergraduate studies he was heavily involved in the maintenance of the 1902 Car mascot of the City and Guilds. This along with a keen interest in the fundamentals of engineering inspired Ben to take on a PhD in the Imperial College Tribology Group focusing on surface fatigue of gear and bearing applications. Ben was awarded his PhD in 2022 and shortly after continued his career within the R&D department of PCS Instruments. Here, together with his fellow R&D engineers, he has contributed to the development and release of a system to allow research of electrified contacts as well as high speed twin disc machine focusing on high speed EHL. Marc Ingram has over 10 years experience working in Tribology.  His masters degree in Chemistry and PhD in Engineering (Tribology) helps him easily bridge the gap that so often exists between lubricant formulator and field/test engineer.  He has worked with all major oil and additive companies after a successful career at Imperial College, PCS Instruments and Afton Chemical.  Marc has extensive knowledge of all tribology test methods inc For more information on STLE, please visit https://www.stle.org/ If you have an idea for our podcast, or interested in being a guest, please Email STLE Director of Professional Development Robert Morowczynski at [email protected] .   Also, we love your feedback, please take a minute to provide us with your thoughts at Perfecting Motion Podcast Feedback or Email us at [email protected].
