Description
The CD74/XL75 Metering Roller Bolt is a critical component in the dampening system of Heidelberg offset printing machines. This bolt secures the metering roller, which precisely regulates the flow of dampening solution onto the printing plate. By maintaining the roller’s stable position, it ensures uniform water distribution, preventing issues such as over-inking or ghosting that can compromise print quality.
Designed for seamless integration with Heidelberg CD74 and XL75 models, this bolt carries the part number L2.030.308 and fits within the Water Rollers category of the dampening system. Its compatibility guarantees reliable performance without modifications, supporting the operational efficiency of these high-volume production presses.
In maintenance routines, the metering roller bolt plays a key role in sustaining system integrity. Regular inspection and timely replacement help avoid misalignment or wear that could disrupt dampening precision, thereby extending the lifespan of the roller assembly and minimizing downtime in demanding printing environments.
