Axel Springer commissioned PrintHouse Service, a subsidiary of KBA, to check, maintain and if necessary, replace the bearers and cylinder bearings on all 18 Colorman rotary presses at its Ahrensburg, Berlin and Essen plants. Predictive maintenance is an evolution of traditional maintenance strategies and a vital element of KBA 4.0, the company said. PHS will measure movement in the bearings to identify possible damage to cylinder bearings so that signs of wear can be detected before printing problems occur. PHS also performs checking and setting of the highly loaded bearers on the impression cylinders.
