Harmonic reducer is mainly composed of the harmonic generator, fexible wheel, rigid wheel three basic components, in addition to rgid bearing (cross roller bearing) and fexible bearing (thin wall deep groove ball bearing).


The inner hole of the fiexible bearing is matched with the elliptical cam outer ring. The outer ring is elastically deformed by the ball to match the inner diameter of the opening of the fiex spline. The gear on the outer periphery of the opening of the fex spline meshes with the teeth of the rigid gear. The number of teeth of the rigid wheel is more than that of the fiexible wheel. The flexible wheel and the rigid wheel are meshed on the long axis and separated on the short axis. The bottom of the fexible wheel is fxed at the output end, and the rigid bearing is installed at the output end of the reducer to connect with the outside. 

This listing is for P5 precision bearings

This bearing can be adapted to HD harmonic reducer, the bearing model corresponds to the harmonic reducer model, this bearing can be adapted to HD harmonic reducer at all levels of reduction ratio and input speed, to buy this bearing, please check the dimensions of each parameter, cross-country transportation costs are high, do not accept returns and refunds because of purchase errors, thank you!
