Lubrication & Lubricants

12 & 14 January 2021

Online via MS Teams

This seminar will give a general introduction to lubrication followed by talks on specific types of lubricants such as oils, greases and dry lubricants.

Lubrication is an important part of machine maintenance, such that lubricating oil alone can increase the life of a combustion engine from a few seconds to more than 5,000 hours. This is possible even though the oil film is sometimes less than one micron thick. In general, only few sliding contacts can run without lubrication due to high friction and wear.

Lubricant quality, however, often deteriorates over time. Condition monitoring is, therefore, in many cases crucial to ensure optimal production conditions. This raises another important question: How do we dispose of used lubricants? By burning or recycling? Recycling of traditional oil-based lubricants benefit from a lower carbon footprint and support a more sustainable circular economy.

But what if oils and greases are not suitable lubricants due to e.g. very high operating temperatures, operation in vacuum conditions or demands on cleanliness. In these cases dry lubricants or self-lubricating coatings may be part of the solution.

All these topics and more will be discussed as part of this seminar.

Target audience
The seminar is aimed at mechanical engineers, industrial and production technicians, tool makers, machine designers and constructors, etc.

Lubrication basics

Ion Sivebæk, Associate Professor, DTU Mechanical Engineering & Research Scientist, Novo Nordisk

Lubrication is basically a viscosity pump. If there is no pressure build-up, the lubricant will be squeezed out very rapidly. In a roller bearing the viscosity pump creates a very high pressure: Up to several GPa (1 GPa is equivalent to 10000 atm.) This pressure is so high that the metal surfaces are deformed elastically. Therefore it is called elasto-hydrodyamic lubrication. At the same time the film thickness is very small, down to below one micron. The presentation will review various cases on lubrication and explain the calculations behind.

Ion works 1/3 of his time as Associate Professor in NanoTribology at DTU Mechanical Engineering and 2/3 of his time as Research Scientist in Tribology at Novo Nordisk, Device R&D.

Maintaining ultra-thin oil lubrication films increases machine reliability

Steffen Dalsgaard Nyman, Corporate Trainer & Noria Partner, C.C. Jensen & CleanOilConsult

The lubrication oil film separating heavy loaded machine components is incredibly thin – often 1-3 micron, meaning below 3/1000 of a millimeter. Maintaining this oil film intact means life or death for the components, so machine reliability, efficiency and uptime depends heavily on this thin oil film. The presentation will focus on:

  • How lubrication and machine reliability are linked
  • Lubrication film thickness
  • Best practice in oil maintenance
  • Cases showing savings achieved by proper oil maintenance
Steffen Nyman earned his BSc degree in Mechanical Engineering in 1996 and joined technical sales for three and a half years. Since February 2000, he has been responsible for developing and conducting technical training and documentation for sales, service and technical staff. He is certified Machinery Lubrication Analyst I & Technician II as well as 4-MAT trainer in adult teaching skills. He has worked as Corporate Trainer for C.C.JENSEN since 2004, conducting hundreds of customized seminars in understanding oil maintenance including oil filtration technologies for the Marine, Mining, Power, Off-Shore and Wind industries. He has been representing Noria Corporation in Denmark since December 2012, through the company CleanOilConsult.

Fundamentals of synthetic lubricants (online from USA)

Jay Weikel, Engineering and Business Development Manager, Nye Lubricants

Fundamentals of Synthetic Lubricants will focus on synthetic grease technology and lubricant selection.  Since the base oil is vital to the performance of greases, the major chemical families will be reviewed for their fundamental properties.  There is a description of the fundamental lubrication related testing to make it easier to understand the data typically presented in technical bulletins.  Other factors that influence grease performance will be reviewed and finally, we will review case studies to see how the proper lubrication solutions are selected.

Jay Weikel has a Bachelor of Science in Chemical Engineering and a Master’s Degree in Business. He has over 28 years of experience in Lubricants and their applications. He is a member of the Society of Tribologists and Lubrication Engineers (STLE) where he is a Certified Lubrication Specialist and a Certified Grease Lubrication Specialist from the National Lubricating Grease Institute (NLGI).

Why put lubricants in friction materials?

Nicholas Ishii-Dodson, R&D Manager, Roulunds Braking

An introduction to dry friction and its application for brakes will be followed by some information about production of the brake pads. A friction formulation can consist of up to 25 ingredients which interact in many ways and at varying conditions of speed, pressure, and temperature.  The technical focus will include a review of the lubricants used and their roles within the formulations, thus providing the background for the use of the name “friction stabilizers”.

After studying Materials Science and Metallurgy, Nicholas started in the brake business by looking at transfer films on brake discs with the Scanning Electron Microscope in a university research programme. Following this he worked at TMD Friction in Research and Heavy Vehicle Brakes Development for 5 years in the early phase of air disc brake adoption, then as a friction and NVH specialist at Bosch in France, Japan and the USA. Currently he is Research and Development Manager at Roulunds Braking, a member of MAT Holdings Inc and is still fascinated by the endless possibilities of formulating friction materials.

DLC coatings for solid lubrication

Henrik Horup Reitz, Senior Consultant, Danish Technological Institute

PVD coatings from the self-lubricating DLC-family are becoming increasingly used for dry lubricating purposes, as well as a supplement for traditional liquid lubrication with oil and grease. Even water may often become a satisfying lubricant, if the “bearing” surfaces are manufactured with the right choice of material and combined with a suitable kind of DLC coating. A good example is the food and pharmaceutical industry, where some bearings and other moving parts are often “lubricated” by the product, followed by very intense cleaning procedures that remove the lubricating substances. In these cases, a DLC coating of one or both mating surfaces may often be a solution to avoid severe damage of the parts.

Henrik Horup Reitz, MSc in mechanical enginering. Henrik has 30 years' experience in tribological topics such as wear and lubrication. Since 1991 he has been employed at the Tribology Centre at DTI, working in the field of applying PVD coatings as solutions for a wide area of tribological problems.

What can testing of lubricants tell you about their status?

Ann Fenech-Andersen, Lead Specialist, Materials & Processes, Danfoss A/S

Condition monitoring of lubricants is essential in order for production to run smoothly. However, it relies on correct interpretation of the results and proactive action. In this presentation the common tests used for testing of lubricants will be presented, with a focus on water-based metalworking fluids. This will be supported with real-life troubleshooting cases to show how test results can help decision-making to stop potentially expensive or even dangerous changes from being made.

Ann Fenech-Andersen is a lead specialist at the Danfoss Technology Centre with a focus on lubricants, component cleanliness and surface treatments. Ann has a B.Sc (Hons) in Chemistry and Biology from the University of Malta and a PhD in materials science from University College London and is a member of the Society of Tribologists and Lubrication Engineers (STLE)

Used lube oil re-refining – an example of real life circular economy

Leon Sloth Skovbo, Managing Director, Avista Oil

Lubricants don’t mean much to most people, yet the world as we know it wouldn’t work without them. The vast majority of lubes is produced from crude oil as a by-product from fuel production. In contrast to fuels, lubricants can be re-refined and used again and again. This is what they do at Avista Oil. They collect used lubrication oil, re-refine it and sell it back into the market where lubricant blenders substitute virgin oils with re-refined base stocks. This cuts their carbon footprint significantly. This presentation will give insight into Avista oil’s niche industry and give ideas as to what you can do to support their efforts in the circular economy.

Leon Sloth Skovbo, BSc in business economics and MBA, has been with with AVISTA OIL Danmark A/S and now AVISTA Green for almost 11 years.
