Breaker stacks

Handling misalignment and expansion for improved reliability

The breaker stack is a single-nip press positioned in the dryer section. Its function is to achieve smoother paper than can be obtained by the machine calendering process alone.

Like most applications in a paper machine, breaker stack 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.
