1. Bearing Maintenance and Lubrication

Topic 1 - BEARING MAINTENANCE AND LUBRICATION

INTRODUCTION

Bearing is a device to allow constrained relative motion between two or more parts, typically rotation or linear movement. Bearings may be classified broadly according to the motions they allow and according to their principle of operation as well as by the directions of applied loads they can handle. Poor bearing installation and lack of proper maintenance, results in major machinery breakdowns, which are losses business and customer services.

This course address every factor that impacts bearing service life. Emphasis is on understanding bearings and improving bearing performance, which in turn improves the reliability of equipment in which they are installed. By attending this training, participants will be able to do proper maintenance of equipment and prevent equipment breakdown.
