For highly dynamic applications

“Our original gearbox on one of our processing lines failed often and prematurely due to overheating; actually boiling the oil inside. These gearboxes would cause downtime/stops on our line fairly often. After repairing oil leaks, fan kits and adding a water-cooled line to keep the gearbox cool we made the decision to invest in a STOBER gearbox. To this date, this gearbox has not had an issue since it was installed in 2016.”

Nicholas Richardson – Maintenance/Engineering, Large Baking Plant
