SIC marking has three competence centres
in europe, America and Asia, enabling it to offer specific solutions, developed and studied locally. Thus, the team dedicated to the customer's needs is perfectly capable of adapting to the various contacts, whether they are multi-site, process, workshop or line managers. The particulars of the different sites are carefully studied whether it’s the surface area available, the technologies for conveying parts or the environmental constraints. This ability to provide multi-site support is highly appreciated by the eTIs and large international groups that place their trust in SIC marking. The laser marking specialist had the
opportunity to prove the qualities of its solutions by taking up the challenges proposed by a major Swedish ball bearing manufacturer with a presence in germany. The manufacturer wanted to mark an alphanumeric and Datamatrix code on steel bearings with diameters ranging from 150mm to 600mm. In addition to adapting to the different part sizes, the solution had to be integrated directly into the production line and be able to mark the bearings in two places at the same time, while ensuring that the Datamatrix was read back. With its many years of experience, SIC marking was able to offer a customised station, equipped with an IPg 50W laser, marking on the bearing face and an IPg 3D laser, automatically controlled on two axes, capable of marking on the part radius. A proofreading system was also integrated in order to proofread the marking directly, as well as a conveyor belt, allowing the machine to be integrated into the production line. In addition to a solution that perfectly met
the specifications, SIC marking was able to convince the customer thanks to its dedicated organisation, local support via its german subsidiary and a major marking test campaign that mobilised its laser experts.

bearing life, leading to costly production stoppages. As a result, the plant worked closely with the Technical Department at leading bearing specialist NSK to assess the application and propose and implement a solution based on high-performance spherical roller bearings. By adopting the recommendations set forward by NSK, the steel plant is now saving €69,803 per annum in reduced costs for downtime, maintenance, bearings and lubrication. When performing a technical root cause

failure analysis, NSK’s expert team closely analysed the working conditions, as well as the lubrication regime to optimise running conditions and prolong life. Furthermore, in support of the maintenance department’s request for process improvement, NSK undertook a review of the bearing fitting process and tolerances. Working in partnership with the steel
plant, the information from the analyses and reviews indicated that the high running temperature of the bearing was emanating from a combination of incorrect fitting and lubrication failure due to higher productivity (running speed) at the plant. Among the many recommendations was
the implementation of NSKHPS (High Performance Standard) spherical roller bearings with higher radial internal clearance to better suit the application conditions. Spherical roller bearings from NSK can withstand arduous operating conditions. These bearings resist seizure and wear in spite of constant vibration, misalignment and shock loads. As a result of the new measures, bearing consumption at the steel plant has reduced
or the past four years a hot rolling mill at a steel plant in Spain had been experiencing unexpectedly short
to one fifth of the previous level, with subsequent benefits in less production downtime and maintenance. NSKHPS spherical roller bearings not
only offer temperature stability up to 200°C, but a dynamic load rating some 25 per cent higher than the industry standard. The upshot is a bearing that provides twice the operating life of conventional alternatives. Aside from advanced motion technology,
NSK can offer customers extensive guidance on maximising the performance of bearings. In the case of the hot rolling mill application, the result of this advice was greater bearing life. However, the company can add value in many other ways, including the generation of higher productivity, the reduction of stock/inventory, enhanced customer skills through targeted training, delivering on-site inspection and/or installation services, the provision of technical reports or lubrication analyses. The steel plant was very pleased with
NSK’s recommendations and their subsequent benefits, as evidenced by a new order for NSKHPS spherical roller bearings when the market started to recover from the effects of the COVID-19 pandemic at the beginning of 2021.
