Machinery Bearings, Lubrication & Reliability (Engineering Tribology)

Introduction

Bearing and Lubrication course is a comprehensive, highly practical and interactive course. This course is designed to provide participants with required working knowledge for better Selection, Installation, and Operation and made on Troubleshooting & Maintenance of Bearing and Lubrication Problems they may experience in their Plant Equipment.

Bearing and Lubrication plays a vital role in the performance and life of rolling element bearings. The most important task of the lubricant is to separate parts moving relative to one another (balls or rollers and raceways) in order to minimize friction and prevent wear. A lubricant that is designed for specific operating conditions will provide a load-bearing wear protective film. The ideal condition is when the friction surfaces are separated by this film. In addition to providing this load-bearing film, the lubricant should also allow for the dissipation of frictional heat thus preventing overheating of the bearing and deterioration of the lubricant and provide protection from corrosion, moisture, and the ingress of contaminants.

This course covers real-world bearing lubrication in a dynamic, skills-based learning approach. Upon course completion, students will have learned the skills needed to choose, apply and maintain lubricants, and lubricating procedures in bearing applications plant-wide. Case histories will be used to demonstrate concepts and stimulate discussion. The participant will be guided examples, and then apply concepts to arrive at practical solutions to their own in-plant situations.

Objectives

By the end of the training, participants will be able to:

• Understanding Bearings and Lubrication Technology
• Determine the types of Bearings and Methods of Lubrication for different equipment
• Know how to test and recognize the Lubricant Properties
• Understand the Lubrication in Different Machinery
• Learn to apply the Troubleshooting Techniques, Maintenance Tips, and Failure Analysis of Bearing
• Identify measure and install bearings commonly used in rotating equipment found in the industry
• Understand the Bearing Maintenance Strategies
• Understand the functionality of vibration protections that are widely used in industries 

Training Methodology

This is a highly interactive training course with opportunities to advance your opinions and ideas. Participation is encouraged in a supportive environment. To ensure the concepts introduced during the program are understood, they will be reinforced through a mix of learning methods, including lecture-style presentation, open discussion, case studies, simulations and group work.
