Unheated plain calender rolls

Increase running accuracy and simplify mounting and dismounting

When it comes to calendering, it is important that the gap between the rolls is constant, to ensure an accurate press nip and good quality paper. Because calender bearings operate at high speeds, high running accuracy is critical in this process.

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

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