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 |
