The Ultimate Guide to Babbitt Bearings: Superior Friction Control and Durability
Introduction
Babbitt bearings are indispensable components in countless industrial applications, renowned for their exceptional wear resistance, adaptability, and low friction performance. This comprehensive guide explores the fundamental principles, benefits, and practical considerations of babbitt bearings, empowering you to make informed decisions.
Understanding Babbitt Bearings
Babbitt bearings are plain bearings composed of a soft bearing metal known as babbitt, typically an alloy of tin, antimony, and copper. They are typically cast into a bearing housing and provide a low-friction sliding surface for rotating shafts.
