Introduction

A tyre manufacturer had some bearing issues on its wire manufacturing machine for the production of multi-material wires. After dismounting the machine for retrofit, some difficulties occured after the bearing re-assembly, resulting in some noise. An NSK engineer analysed the machine on site and the bearing condition. The design analysis revealed the complexity of the mounting situation compared to the application. Furthermore, the bearings were not appropriate for the load conditions. NSK made a report and recommendations for an easy, reliable mounting with standard bearing. After the modifications, the customers conducted some trials and no noise issue was detected. With the NSK solution, the reliability of bearing mounting was increased.
