A medium capacity Centri-Sifter centrifugal screener model MO from Kason features a cantilevered shaft with two, externally-mounted bearings between the screening chamber and motor drive, allowing internals to slide freely from the shaft end for cleaning, screen changes, or inspection. Wide spacing between the bearings, a large diameter shaft, and a flexible shaft coupling combine to prevent vibration, even at high speeds under heavy, imbalanced loads, according to the company.
