The cam bearing in a cycloidal concrete pump supports the eccentric cam shaft that drives the pumping pistons through their stroke cycle. It absorbs the continuous rotational and radial loads generated during pumping, keeping the cam centered and the piston timing accurate. When this bearing wears or fails, the cycloidal mechanism loses its smooth rotation, leading to uneven piston strokes, reduced output pressure, and accelerated wear on surrounding drive components — making timely replacement critical to pump performance.
