An international steel manufacturer experienced regular failures on bearings in a continuous casting machine. This machine is used in the production of shaped sections and due to that, the bearings have to handle heavy loads. The problem was a short bearing life of the standard bearings due to wear and fatigue. The average bearing life was 124 weeks and they had experienced 3 failures to date. After an investigation, NSK suggested to apply a durability test with NSK’s SWR Spherical Roller Bearings. These bearings are made of specially developed bearing steel, which has a much better wear resistance and resistance against fatigue. With the NSK solution, the customer could achieve a significant cost saving.
|Before||Cost p.a.||NSK Solution||Cost p.a.|
|Production loss due to bearing failures||€ 100.000||No production loss||€ 0|
|Manpower costs for replacing the bearings||€ 40.000||No manpower costs||€ 0|
|Total Costs||€ 140 000||€ 0|
