Bushing for Putzmeister machinery

The bushing 028550008 acts as a bearing surface for pins or shafts in heavy machinery. It is designed to manage rotational movement at articulation points, providing a interface that facilitates smooth operation between moving components. By maintaining the correct clearance at these joints, the part helps preserve the integrity of the surrounding structural elements.

This component is manufactured to the DU-B specification with dimensions of 90 mm by 95 mm by 60 mm. It is intended for use in various Putzmeister equipment, including concrete pumps and tunneling machinery, where it is installed in pivot points such as boom articulations or steering mechanisms. Proper sizing is required to ensure a correct fit within the housing and onto the mating pin.

Bushings are installed in mechanical systems to support rotating or oscillating shafts. They function by distributing the load across the surface area of the joint, which minimizes concentrated pressure on the pins and the structural frame. Regular inspection of these components is standard practice to prevent excessive play in the assembly, which can otherwise lead to accelerated wear of the primary structural bores.
