transmission shaft

The transmission shaft component is a component set to reduce the axial and radial friction between the rotating body shells. The transmission components of the drilling tools produced by our company have different structures. The drive shaft component with a water eye pressure drop of 3.5 MPa adopts radial bearings at the top and bottom, and a thrust ball bearing in the middle. The drive shaft component with a water eye pressure drop of 7.0 MPa adopts cemented carbide radial bearings at the top and bottom, and a thrust ball bearing is installed in the middle. Group, improve the carrying capacity and service life of the drive shaft.
