"Bearings For Iron and Steelworks", a new twelve page publication from NSK highlights the comprehensive and strategic role played by NSK's range of bearings in all areas of steel making, including casting, rolling, finishing, raw material handling and iron making(Plate 13).

Plate 13 NSK underlines strategic role of bearings in steel making with new, highly focused publication

NSK's production of the new publication is a response to the continuous pressures to reduce maintenance costs within the steel industry, and is also a recognition that the operating conditions of bearings used in the production of steel are among the toughest encountered anywhere. As a major supplier of rolling element bearings to the industry,

NSK has studied these operating conditions and through an extensive research programme has made improvements in bearing materials, lubrication and sealing technology.

The new publication outlines products which are the result of these improvements; technological advances that make failures in the continuous production cycle that much more unlikely. The products include NSK's new Extra Capacity Roll Neck Bearings, a new design that reportedly delivers up to 34 per cent extra load capacity and longer life under severe lubrication conditions, and the "next generation" EA Series spherical roller bearing. The design of the EA series, accommodating a greater number of larger rollers, means that these bearings have load capacities that are stated to exceed those of the conventional bearings by between 10 to 20 per cent. They also are said to have operational lives some 30 per cent to 80 per cent higher.

Roll neck bearings make use of NSK's innovative Super-TF material, a new steel that has been developed to greatly improve the life of bearings, even in the presence of contaminated lubricant – a common condition in steel making. NSK asserts that in comparison with bearings made of conventional carburised steel, Super-TF bearings offer up to 10 times the operating life under contaminated lubrication conditions and approximately 5.5 times operating under boundary lubrication condition.

The twelve pages of the new publication are presented in a particularly informative format, employing graphics almost exclusively, not only to highlight the features of bearing products, but also to provide cutaway sections of products and graphs of performance, service life and durability. The fold out, easy-to-use format also includes a full colour schematic of a continuous casting process. At each stage of the process the NSK bearing product or products, that have been developed to provide improved operation in that area, are depicted.

Free copies of the new Steel Publication are available via NSK's Freephone service on 0500 2326474. Callers should quote the catalogue reference, El 230 and also the title of the publication: Bearings For Iron and Steel Works.
