Bearings: Introduction

This lecture covers the definitions, classification, assembly, and sizing of bearings, with illustrations from the SKF general catalog. It explains the advantages and disadvantages of rolling bearings compared to plain bearings, the building blocks and terminology of bearings, sources of friction, and the nature of materials in contact. The lecture also discusses hydrodynamic bearings, radial internal clearance, factors influencing radial play, and the importance of proper assembly and clearance. It concludes with a synthesis on the types of bearings, their load capacities, and friction levels.
