Harmonic reducers, also known as harmonic drive gears or strain wave gears, are precise mechanical devices used to reduce speed and increase torque in various applications. They rely on flexible elements and harmonic waves to achieve motion. Bearings are a critical component in harmonic reducers, supporting their smooth operation and long lifespan.
