2021 Fall and 2022 Spring Program

Toronto Section Chair’s Welcome

On behalf of STLE Toronto Section, I would like to welcome you to our 2021-2022 program. Starting last year, STLE Toronto held several education webinars on-line and we will continue until we will have a safe environment for our attendees.

Our focus will be “cost savings” and / or “manufacturing cost reduction” based on better lubrication, better practices, and / or automated data gathering and processing. These helpful webinars will educate and empower attendees to contribute more to the company through these tough times.

I welcome you all on this program and hope to see you all there.

Our technical program over the last few years was based on half day in-person workshops featuring 5-6 speakers. This worked well but with the current concerns about the Covid 19, we are adapting. A short survey determined that the most popular was a talk 30-45 minutes long, on one topic, and held mid-morning. We are also going with live video audio webinars which allows our participants to attend from wherever they are working and there is no time lost for travel. Plus, questions can be submitted in advance or during the presentations. As before we are focusing on technologies that can help save your company resources. This can be better as it might help tribological products last longer, save energy, reduce waste, and/or increase productivity. Win, win, win!

The STLE Toronto Section uses events like this to help spread the word and also to raise funds. These funds are used to support the section activities and to provide donations and assistance to local universities and colleges. No money raised goes to salaries or expenses.

Webinar Notice May 10, 2022 – 1 to 2 PM EST Speaker; Rick Klassen -Klassen Advanced Filtration – Subject: Varnish



In-service lubricants suffer from various forms of contamination and degradation. Varnish, a sticky and somewhat transient contaminant, has become an increasing problem in turbine and hydraulic lube systems. Thermal stress, oxidation, solid particles, and moisture contamination all contribute to varnish formation. Left unchecked, varnish can cause many operational issues and premature wear of critical components.
We will discuss the causes, effects, and possible solutions for varnish.
1. Causes
2. Testing methods
3. Oil changes as a solution?
4. What is and isn’t varnish?
5. Case studies
