Couplings, Gears, Bearings, Seals & Lubrications

The most critical elements of any rotating piece of machinery will ultimately be the coupling, gear, bearings, and seals. They are the most common cause of equipment failure and can be the center of some of the most expensive break downs. Immense pressure is on repair companies these days to provide high quality repairs at low costs. Knowing how to both identify the root cause of bearing failure and repair the machine to a standard that is better than when it was originally made is the key to great service.

This training course explains the purpose of coupling, gear, bearings, & seals and demonstrates how bearings and lubrications reduce friction and maintain the alignment of operating equipment. It explains and demonstrates how to clean and disassemble bearing housings & gearbox and how to dismount, inspect, and mount common types. The importance of full fluid film lubrication and proper lubrication clearance is demonstrated. Additionally, indications of various premature bearing and gearbox failures are discussed with laser shaft alignment training.
