A new version of the software for rolling bearing analysis according ISO/TS 16281 is available.

The main changes are the analysis of tolerances and the possibility for calculation of groups of bearings.

The bearing clearance can be defined according ISO 5753 C2-C5 in addition to a manual definition. Using the bearing tolerances PN to P2 according ISO 492, the tolerances of shaft and housing according ISO 286 and the temperatures the operating clearances can be defined. The extension of the inner ring because of centrufigal loads is considered too. With a simple selection the calculation can be done with minimal, maximal or medium clearance.

In addition to the calculation of a single bearing also groups of bearings can be calculated now. Especially angular contact bearings are often used in groups at a single shaft support. But also planetary gears are often supported by several bearings or an 8-point slewing ring can be calculated using two 4-point bearings. The load distribution between these bearings can now be calculated by the software.
