BEARINX is designed to help users calculate the energy efficiency of different rolling bearing designs in any application. For example, after using the software, the user may decide to specify rolling bearings with reduced friction characteristics, or to downsize the bearings and/or other related system components. The software takes into account the internal load distribution of the bearing and contact pressures on the raceways and ribs, with the actual rolling element profiles. The new software module utilises a friction calculation theory based on physical algorithms confirmed by a series of tests on rolling bearings. Bearing life is calculated according to ISO/TS 16281. As well as load distribution and rating life, the software also enables users to calculate the frictional torque of rolling bearings and therefore the power loss of entire shafts or power transmission systems. The system is available online and free-of-charge to users and customers at http://BEARINX-online-easy-friction.schaeffler.com.
