  • Rotary Bearings Design Guide

    Rotary bearings are mechanical components that bear a load — such as an electric motor’s output shaft — while minimizing friction to allow for the free turning of that axis in one (most common) or two planes. In most cases, they’re the support interface between rotating and stationary portions of the assembly.
