The printing unit is the heart of a sheet-fed offset printing press. The colour is transferred to the paper sheet by means of a plate cylinder, blanket cylinder, impression cylinder as well as ink and damping rollers. Transfer cylinders and transfer drums feed the paper sheets from one printing unit to the other. Many cylindrical bearings require a backlash and friction-free function, to ensure a smooth paper feeding and an uniform ink distribution, at printing speeds up to 18,000 sheets/hour. LUBCON bearing greases for the cylinder bearing lubrication in printing machines offer a high load carrying capacity and very good lubricity at high speeds. They reduce thus bearing forces, vibration, friction as well as wear and have positive effects on the printing image quality.
