Duration 5 Days
Introduction:
This course is designed is to provide pertinent information and practical insight to the participants for improving the performance of rolling element bearings, which then enhances the reliability of rotating equipment.
The course is designed for participants to understand the functions of bearings in relation to rotating equipment, its installation, its performance and to know the major signals/symptoms of Bearing failure.A basic understanding of the principles and practices of predictive maintenance is also covered.
Participants can use the skills and knowledge gained in this course to: Minimize bearing failures in equipment thus reducing downtime and cost; Perform regular preventive maintenance on equipments; and Quickly respond to bearing-related equipment and system failures.
The course discusses the modes of failure of bearings in equipments, how to check root cause and what methods available to eliminate them for the future.
Who Should Attend
The course is ideally suited for Maintenance Engineers, Service Engineers, Operations staff, and Machine repair persons from any industry using rotating equipments. It is recommended for Managers and Engineers responsible for bearing performance and reliability. Rotating equipment engineers, reliability engineers, millwrights, mechanics, maintenance supervisors and anyone interested in rolling element bearing and rotating equipment performance will find it useful.
