Vacuum rolls

Extending bearing service life and reducing maintenance costs

Vented steel rolls, sometimes known as through air dryers or PV, positive ventilation rolls, have replaced or complemented some of the drying cylinders in modern drying sections. Despite the presence of heat, the operating environment is not excessively demanding. However, like most applications in a paper machine, these rolls are subject to misalignment and axial expansion of the shaft, which the bearings must accommodate.
