Axial and radial rigidity
The FAG bearing arrangement in machine tools is subjected to frequently changing requirements. In order to achieve the highest possible machining accuracy, the aim must be to achieve high basic rigidity values.
Increased radial rigidity
When FAG cylindrical roller bearings NN30 are used, this gives the arrangement with an axial angular contact ball bearing 2344 and the arrangement with axial bearings BAX a rigidity that is approx. 2,5 times higher than in the case of FAG four spindle bearings B70 of the same size.
