With the rapid development of technology, the printing press industry is also undergoing revolutionary leaps, and people have put forward increasingly high requirements for single sheet and roll plate offset presses. Under high-speed operation and low cost conditions, it is required to achieve high efficiency and high printing quality. As a crucial component of rotational support, bearings have shouldered the heavy burden of the development of printing machines. German SFL bearings have been widely used in the printing machinery industry due to their unique selection and design of retainers, precision, clearance, and other features.
