IntroductionThe rod mill chocks in the plant of a steel manufacturer were fitted incorrectly with the incorrect spacers, causingfailures and the need to source high cost urgent replacement bearings. Maintenance staff unaware of the spacercalculation, they work off a Standard Operating Procedure that was 20 years old. Correct fitting instructionspresented and demonstrated. NSK engineers were present during replacement and trained the staff on fittingpractices. Genuine NSK bearing replaced the current high cost bearings with significant savings at purchase.Customer standard operating procedure with spacer calculations updated and re issued.
