In an European steelworks, the back-up rollers of a competitor failed after a short time in the test phase. Initially, the project was awarded to the competition. After multiple failures, NSK engineers were consulted for technical support and proposed to use NSK cylindrical roller bearings with optimised innerring sideswasher for an increased life time. The estimated lifetime is now at over 1,5 years without any failures. This helps to reduce the machine downtime and the maintenance cost drastically.
