Bearings for rolling mills: new online training module added to NSK academy

The nature of processes such as steelmaking and ironmaking mean that heat, contamination, heavy loads, vibration and impact are just some of the issues facing bearings required for use in rolling mills. NSK’s latest online training module aims to explain how the effects of these problems can be minimised through optimised bearing specification.

Included within the course is an overview of metal manufacturing processes, in particular the many different types of rolling mill used to form the product. Characteristics such as rolling load flow are covered in detail as this is particularly relevant for bearing design and selection.

The module also encompasses a close look at the bearing technologies best suited to particular areas of the rolling mill, such as the work roll and back-up roll assemblies, and how their attributes match up to the operating conditions typically encountered.

Correctly specified bearings promote longevity and save costs by reducing maintenance, repairs and rolling mill downtime. With this thought in mind, another major factor addressed by the new course is TCO (total cost of ownership), which draws comparisons between sealed and open-type bearings.

Bearings for Sendzimir mills, or Z-mills as they are sometimes known, are also covered in NSK’s new online course.

The training module has been devised to help rolling mill OEMs and maintainers understand the fundamental principles behind bearing selection. Those involved in product sales, technical support, maintenance, engineering or R&D can all benefit.

All those participating at the NSK academy are able to grow the knowledge they use on a daily basis, and take advantage of the latest NSK bearing solutions to maximise machine life.
