3E907KAT2 Flexible Bearing for Harmonic drive

• The 3E907KAT2 is a thin-section flexible bearing dedicated to harmonic reducers. It serves as the core critical bearing for the harmonic drive system to achieve high reduction ratio and zero-backlash transmission, and has been maturely applied in high-end scenarios such as aerospace and industrial robots. When matched with a harmonic reducer, it can realize nearly zero-backlash transmission, deliver excellent repeat positioning accuracy, high torsional rigidity, and extremely small angular deformation under load. Its transmission efficiency reaches 80%-90%, and it can achieve a single-stage high reduction ratio ranging from 30:1 to 160:1 within a compact and lightweight structural space. This bearing model is widely adapted to high-end scenarios with strict requirements for transmission accuracy, volume and weight, including collaborative robot joints, semiconductor wafer handling equipment, aerospace satellite antenna pointing mechanisms, precision optical positioning platforms, and surgical robots.
