Now, the rapid development of science and technology, also gave birth to the revolutionary leap of the printing industry. People on the printing plate offsctdruckereien version and the scroll version offsctdruckereien requirements are getting higher and higher. Many printing companies bought advanced imported presses. According to the design requirements and performance of the imported printing press as a key component, can be rotatable support on the bearing shaft to lift the shoulder press, imported printing press using a large number of imported bearings. Bearings can support the machine, can also be used to fix the shaft, also affect the transmission. Previously, bearings such as cylindrical roller bearings or roller bearings were integrated into a common bearing sleeve. Then it is precisely installed on the side wall of the frame, which is an important part of printer maintenance work. In the condition of high-speed operation and low cost, in order to achieve high efficiency and high printing quality requirements, due to the complex high-precision press bearing and roller bearing structure, this kind of bearing has been monopolized by foreign well-known manufacturers. INA bearing has been committed to improve the service life of printing presses, high quality, high efficiency, energy saving and environmental protection, good economy, so please correctly buy and use imported bearings
