2022 Fall and 2023 Spring Program

Toronto Section Chair’s Welcome

On behalf of STLE Toronto Section, I would like to welcome you to our 2022-2023 program. Starting two years ago, 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.

STLE Toronto Section Chair. 2022-2023



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.

Why Should You Attend?

It has been reported many times that the vast majority of rolling element bearings do not reach their design life. That life is based on subsurface initiation fatigue cracks propagating to the surface to form pits. This is the L10ha life. Consequently, it is very very important to know why a bearing failed or if replaced but had not failed as such, whether it was in distress. With this information you can take steps to get some or all of the following benefits; extend the life the bearings, reduce maintenance costs, increase uptime, reduce personal requirements, reduce infant mortality, reduce rework, reduce safety risks, etc.


Rolling bearings are among the most important components in the vast majority of machines. Exacting demands are made on their load carrying capability, running accuracy, noise levels, friction and frictional heat, life and reliability.           

Despite careful design and manufacture as well as testing the bearing in the application, it sometimes happens that a bearing does not attain its required service life. Failures will generally cause economic losses due to loss of production, consequential damage of adjacent parts, and the cost of repairs.

Premature bearing failure can occur for a variety of reasons. Each failure leaves its own special imprint on the bearing. Consequently, by examining a failed or damaged bearing, it is possible in the majority of cases to establish the root cause and define corrective actions to prevent a recurrence.
