Always follow the Roadmap for eligibility criteria for the procurement process of technological bearings.

Always formally define representations and warranties to avoid incurring fraudulent cases, including misleading or deceiving conduct with regard to corporate consistency and reliability.

As a matter of transparency, always request suppliers to show the scientific background (quantitative and qualitative) and technical conformity to related International Standards of the data provided during the process of technical evaluation and compliance.

Never mix RKB rolling bearings with not eligible products on the same equipment or machine.

The manufacturing knowledge, technology, procedures and processes for big size (in particular heavy series and extra-thin series from 260 mm bore on) and technological bearings are extremely complex and critical compared to smaller sizes. In fact from designing and engineering to raw material selection, forging, heat-treatments, machinings, assembling and all related multilevel quality controls, it is state-of-the-art to manufacture a conventional qualified rolling bearing that meets performance requirements and International Standards. Once again RKB suggests, particularly in the procurement process of the above mentioned products, to strictly follow an efficient and reliable homologation roadmap.

Always investigate and formally define the level of integration (in-house operations) of bearing manufacturers to avoid the risk of selecting spurious sources.

Always refer to the Bearing Industry Matrix to better understand the actual positioning of a bearing manufacturer and, consequently, select the most appropriate bearing source according to your specific needs.
