SKF rebuilt rocker housings raise ROI by 633%
The SKF solutionWorking closely with mill technicians, an SKF paper specialist determined that the machines' conventional self-aligning bearing system and rocker housing - which were designed to deal with shaft elongation - could not accommodate the significant changes in shaft behaviour caused by increasingly higher machine speeds.
SKF recommended incorporate a CARB toroidal roller bearing in a rebuilt rocker housing to accommodate misalignment and axial displacement. The rocker housing was also redesigned as a fixed housing.
The resultThis new arrangement resulted in a 663% return on investment, through reduced downtime and increased productivity.
