Heated plain calender rolls

Higher running accuracy at higher temperatures

By heating calender rolls with hot water, steam or very hot oil, a better surface finish is achieved. Machine components in this application operate in a hot environment at relatively high speed. High running accuracy is essential for good quality output.

Furthermore, like most applications in a paper machine, calender rolls are subject to misalignment and axial expansion of the shaft, and the bearings must accommodate this.

Often this is an area that has significant static electricity which can subject bearings to electrical etching.
