The guide rollers guide and drive the wire and felt cloth in the wet end and dry section of the paper machine. The guide rollers in both areas use the same bearings. However, different lubrication and sealing are used depending on the application location. In old paper machines, the wet end section was often lubricated with grease and the dry section with oil. In modern paper machines, both sections are lubricated with oil circulation. Due to different working conditions, the wet end and dry section need to use their own oil circulation lubrication.
It is often seen that the larger the machine, the faster the speed. For this reason, the inner ring of the bearing is directly mounted on the tapered roll neck using a tapered hole.
1. Wet end section
The bearings are affected by temperature to different degrees at different locations in the paper machine. In particular, when the paper machine is undergoing high-pressure cleaning, it must be ensured that water cannot enter the bearing seat.
2. Drying section
The ambient temperature is about 95°C, which will lead to large length changes and therefore high lubrication requirements. The bearing operating temperature can reach 115°C
