Self-aligning cylindrical roller bearings


When drying cylinders are heated, heat expansion causes significant length changes for long cylinder. In addition, misalignment occurs between both bearing positions.

The solution:
Self-aligning cylindrical roller bearings. They are most often used in the dry end and frequently replace the previous solution that involved rocker block housings. Length changes are easily compensated between the rollers and the inner ring raceway in the bearing. The spherical sliding surface of a selfaligning plain bearing ring compensates potential alignment inaccuracies of the cylinders.

Mounted as floating bearings at the operator’s end of a dryer roll or M.G. cylinder.
