Roadmap for eligibility criteria Procurement compliance procedure for technological bearings The knowledge and experience gained over the years, along with the close cooperation with international academic centers, have enabled RKB to establish the steps of the procurement compliance procedure for technological bearings. For reasons of responsibility and transparency, all customers are invited to read thoroughly and follow carefully the following roadmap: (1) Signing of non-disclosure agreement (where required). (2) Commercial evaluation (price, delivery terms and conditions). (3) Technical merit...

As a matter of responsibility, RKB has also developed a series of recommendations in order to help customers choose after due consideration and keep away from unpleasant surprises: Always follow the Roadmap for eligibility criteria in 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 (3) Scientific background and conformity to International As a matter of transparency, always request suppliers to show the scientific background...

BEARING INDUSTRIES PRODUCTION RANGE

Deep groove ball bearings Non-separable, for operations at high speeds, of simple design and little maintenance, RKB deep groove ball bearings are the most versatile and popular bearings in rolling applications. The internal designs are the Conrad assembly (the majority of the production) and the filling slot assembly (for special applications with cage or with full ball complement). The single row deep groove ball bearings can take radial and double direction axial loads. They have limited abilities to compensate for errors of misalignment. Because of the values, in order to avoid inadmissible...

The axial clearance is generally not standardized and depends on the values of the radial clearance, ball size The cage depends on the bearing series and size; RKB single row deep groove ball bearings are supplied with one of the following designs: ribbon type cage of steel or brass sheet, riveted type of steel or brass sheet and machined brass type centered on balls, inner ring or outer ring. Large size bearings are also available in special executions such as lubrication grooves in the guiding surfaces of machined brass cage (suffix MAS or MBS) and/or one notch in the outer ring side face to...

Single row angular contact ball bearings RKB single row angular contact ball bearings are designed to accommodate combined loads acting in radial and axial direction.They can take axial loads in one direction only. When radially loaded, in the bearing occurs an axially acting load which has to be compensated. For this reason one bearing or paired bearings are mounted on each shaft end. These bearings are not separable and their use at relatively high speed is allowed. Manufactured in various constructive versions, they can be with different contact angles, depending on the RKB produces two types...
