Introduction

The rod mill chocks in the plant of a steel manufacturer were fitted incorrectly with the incorrect spacers, causing failures and the need to source high cost urgent replacement bearings. Maintenance staff unaware of the spacer calculation, they work off a Standard Operating Procedure that was 20 years old. Correct fitting instructions presented and demonstrated. NSK engineers were present during replacement and trained the staff on fitting practices. 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.
