How a webinar works

All EASA private webinars are live events in which the audio and video are streamed to your computer over the Internet. Prior to the program, you will receive a web link to join the meeting.

The presentation portion of the webinar will last about 45 minutes, followed by about 15 minutes of questions and answers.

Requirements

Internet connection
Computer with audio input (microphone) and audio output (speakers) appropriate for your size group
TV or projector/screen

Zoom logo

The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Private Webinars

EASA's private webinars are an inexpensive way to bring an EASA engineer into your service center, place of business or group meeting without incurring travel expenses or lost production time.

Much of what will be discussed in this article applies to all rolling bearings, both ball and roller. Our focus, though, will be on issues that relate mostly to ball bearings used in electric motors. The intent is to address some of the fundamentals of rolling bearing enclosures, internal clearances and fits. We deal with rolling bearings every day, but we don’t always consider some of these fundamentals until there is a bearing related problem.

Note: Rolling bearings were previously referred to as antifriction bearings. The American Bearing Manufacturers Association (ABMA), formerly the Antifriction Bearing Manufacturers Association (AFBMA), now terms antifriction bearings as “rolling bearings.”
