Flexible rolling bearing utilizes controllable elastic deformation of the flexible components to transmit motion and power. It has characteristics of large transmission ratio, wide application range, high precision, small air return, large carrying capacity, high efficiency, small volume/size, light weight, smooth transmission, low noise, and can transfer motion to sealed space.

Harmonic drive transmission consists of three basic components: wave generator, flex spline, Circular Spline ａnd flexible bearing. Among them, the flexible bearing is the core component, and the transmission achieves the performance requirement of high deceleration ratio through the elastic deformation of the bearing.

When the flexible bearing is in operation, the inner ring is mounted/installed on the elliptical cam, which bears the cyclic stress load during the work; while the outer ring is mounted/installed on the flexible wheel, and elastically deforms with the rotation of the cam during the work, which not only bears the cyclic stress load, but also withstands the alternating stress load.
