    Applications of harmonic drive speed reducer bearings

    Harmonic drive speed reducer is also called strain wave drive, its main components including wave generator, flex gear, ring gear, and cross roller bearing. The wave generator also contains thin raced ball bearing(flexible bearing). It overturns the traditional power transmission mode, and has the characteristics of small size, light weight, high torque load, high rigidity, excellent positioning accuracy and rotation precision, and is widely used in the following fields:
    – Industrial robot / intelligent robot
    – Multi-axis robotic arm for home or industrial use
    – Precision processing machinery
    – Wind power fan blade control
    – Aerospace and marine science
