A paper machine usually consists of the following parts: wet section, drying section and finishing section. The wet part is divided into forming part and pressing part. The paper passes through a large number of rolls, which are supported by rolling bearings. Spherical roller bearings are widely used in paper machines, especially medium and large bearings with an outer diameter greater than 320mm. Large cylindrical roller bearings are also often used in the design of rollers.GEMAN's spherical roller bearing has enlarged radial clearance design, and its raceway surface super finishing treatment can improve rotation accuracy.Its inner ring with surface carburizing treatment and the inner ring with lubricating oil holes and so on all can provide a comprehensive solution for papermaking machinery.
