MESYS Rolling Bearing Calculation Introduction This rolling bearing calculation (Version 04/2017, File version 3.0) calculates the load distribution, the reference life and the modified reference life according ISO/TS 16281 (DIN 26281) for the following types of bearings: 鈥 Deep groove radial ball bearings 鈥 Double row deep groove ball bearings 鈥 Axial deep groove ball bearings 鈥 Radial angular contact bearings 鈥 Axial angular contact bearings 鈥 Double row radial angular contact bearings 鈥 Double row axial angular contact bearings 鈥 Single row spherical ball bearings 鈥 Double row spherical ball bearings 鈥 Four-point ball bearings considered as radial bearings 鈥 Four-point ball bearings considered as axial bearings 鈥 Duplex ball bearings 鈥 Radial cylindrical roller bearings 鈥 Double row radial cylindrical roller bearings 鈥 Axial cylindrical roller bearings 鈥 Barrel roller bearings 鈥 Needle bearings 鈥 Tapered roller bearings 鈥 Double row tapered roller bearings 鈥 Axial tapered roller bearings 鈥 Radial spherical roller bearings 鈥 Axial spherical roller bearings 鈥 Cross roller bearings considered as radial bearings 鈥 Cross roller bearings considered as axial bearings 鈥 Angular roller bearings considered as radial bearings 鈥 Angular roller bearings considered as axial bearings Additional bearing types will be added in the future. The inner geometry of the bearings can be approximated by the software or provided by the user. The operating clearance can be specified. The influence of interference fits, temperature and centrifugal load on the clearance can be taken into account. Centrifugal loads and gyroscopic moments on the rolling elements can be considered for ball bearings only. In extension of ISO/TS 16281 the influence of reduced material hardness can be considered accordi
